Which value of x makes the equation 3+0.75(x-2)=0.5(x+20)
Answer:
x = 34
Step-by-step explanation:
We need to find the value of x in the given equation :
3+0.75(x-2)=0.5(x+20)
Solving as follows:
3+0.75x-1.5=0.5x+10
Taking like terms together,
3-1.5-10=0.5x-0.75x
-8.5=-0.25x
[tex]x=\dfrac{8.5}{0.25}[/tex]
x = 34
So, the value of x is 34.
Carlos travelled a certain distance from home to the campgrounds on his dirt bike at a speed of 50 km/h and returned at a speed of 60 km/h. How can carlos find the distance between his home and the campgrounds if the total time traveling was 11 hours.
Answer:
110kmStep-by-step explanation:
"Carlos travelled a certain distance from home to the campgrounds on his dirt bike at a speed of 50 km/h and returned at a speed of 60 km/h. How can carlos find the distance between his home and the campgrounds if the total time traveling was 11 hours"
Given data
initial speed u=50km/h
final speed v=60km/h
time taken t=11hours
change in speed= 60-50
=10km/h
we know that the expression for speed is given as
speed= distance/time
let the distance be x
10=x/11
x= 10x11
x=110km
Therefore the distance is 110km

In the diagram shown, what is the measure of angle BAC?
Answer:
Option (B)
Step-by-step explanation:
By exterior angle theorem,
Exterior angle of a triangle is equal to the sum of two opposite interior angles.
By the given theorem,
8x - 30 = (4x + 8) + (2x + 2)
8x - 30 = 6x + 10
8x - 6x = 40
2x = 40
x = 20
m∠BAC = (2x + 2) = (2×20) + 2
= 42°
Therefore, Option (B) will be the answer.

kid just put them in y=mx+b form by isolating the y
Step-by-step explanation:
i'll do #19 for ya
y-4 = 3(x-2)
3(x-2) turns into 3x-6 when u distribute it
y-4 = 3x-6
isolate the y by adding 4 on both sides
y=3x-2
there ~ it's in slope intercept form
Answer:
19. Y = 3x - 2
20. Y = -x - 6
21. Y = -2x + 2
22. Y = -5x + 14
23. Y = 6x - 3
24. Y = 3x + 23
25. Y = 1/2x + 5
26. Y = 1/3x + 2
27. Y = x + 1

a type of green paint is made by mixing 2 cups of yellow with 3.5
find a mixture that will make the same shade of green but a smaller amount
find a mixture that will make the same shade of green but a larger amount
find a mixture that will make the different shade of green that is bluer
find a mixture that will make the different shade of green that is more yellow
Answer:
Anything with 2 Yellow and more than 3.5 Blue
Step-by-step explanation:
The answer is pretty obvious, but I will give a more mathimatical explanation that is easy to understand. The ratio is saying that for every 2 units of yellow, there are 3.5 units of blue. You can find ratios that are the same but use more/ less amounts. So if you use 4 units of yellow and 7 of blue it is the same ratio.
If you multiply both parts of the ratio (or divide) by the same number you will always get the same ratio. So if you want something more blue (or yellow) you just have to keep one the same while increasing the one you want to have more effect.

A bank has a savings rate of 6% simple interest per year. If a customer deposited $4,000 in a new account and does not add or withdraw any money to the account, how much simple interest will the customer make in 4 months?
Answer: The customer will make $80 as interest in 4 months.
Step-by-step explanation:
Given: Deposited amount : P = $4000
Rate of interest per year : r= 6% =0.06
Rate of interest monthly = [tex]\dfrac{r}{12}=\dfrac{0.06}{12}=0.005[/tex]
Time = 4 months
Simple interest = principal x rate of interest x time
[tex]=4000\times 0.005\times 4=80[/tex]
hence, the customer will make $80 as interest in 4 months.
Can someone show me how to do it step by step solving for x,y and z
Step-by-step explanation:
X+106=180 [(being cointerial angle]
or, X=180-106
or,X=74
therefore,X=74
2y=X=74[being corresponding angle]
X+(4z+6)=180[being exterior cointerior angle]
or, 74+6+4z=180
or,4z=180-80
or,4z=100
or,z=100/4
or,z=25

-6x + 5(-2x - 11) = 137
What is x equal to?
Answer:
x=−12
Step-by-step explanation:
−6x+5(−2x−11)=137
Step 1: Simplify both sides of the equation.
−6x+5(−2x−11)=137
−6x+(5)(−2x)+(5)(−11)=137(Distribute)
−6x+−10x+−55=137
(−6x+−10x)+(−55)=137(Combine Like Terms)
−16x+−55=137
−16x−55=137
Step 2: Add 55 to both sides.
−16x−55+55=137+55
−16x=192
Step 3: Divide both sides by -16.
−16x/−16=192/−16
Answer:
-6x-10x-55=137
-16x-55=137
-16x=137+55
-16x=192
X=192/16
X=12

5x - 32x - 9
Answer:
x = -2 :)
Step-by-step explanation:
5x - 3 = 2x - 9
3x = -6
-6/3 = -2
Answer:
x = -2
Step-by-step explanation:
I dunno which one to answer so I'll do both. (the question you posted or the picture??)
5x - 32x - 9
First we can combine the like terms 5x and -32x. Which is -27x
We can't combine -9 with anything so it stays the same.
-27x - 9
________________________________
5x - 3 = 2x - 9
-2x -2x
3x - 3 = -9
Here I subtracted -2 from both sides.
3x - 3 = -9
+3 +3
3x = -6
Divide both sides by 3 to isolate the variable.
x = -2

A tree in Sam's backyard was approximately 14 ft tall. The height of the tree is increasing at an average rate of .003 ft per month. Which function can be used to find the height of the tree in x months since it was measured?
Answer:
[tex]f(x)=0.003x+14[/tex]
Step-by-step explanation:
Let the linear function to represent the height of tree be:
[tex]f(x) =mx+c[/tex]
Where [tex]x[/tex] is the time in months
[tex]m[/tex] is the rate of change in the height of tree each month.
[tex]c[/tex] is the initial height of the tree.
Here, we are given that:
The initial height of the tree is 14 ft.
Increase in the height = 0.003 ft per month
Putting the values in the equation of function:
[tex]f(x)=0.003x+14[/tex]
So, the function [tex]f(x)=0.003x+14[/tex] can be used to find the height of tree in [tex]x[/tex] months since it was measured.
Prove: ∠JNM ≅ ∠NMI
According to the given information in the image, segment JK is parallel to segment HI while ∠JNM and ∠LNK are vertical angles. ∠JNM and ∠LNK are congruent by the Vertical Angles Theorem. Because ∠LNK and ∠NMI are corresponding angles, they are congruent according to the Corresponding Angles Theorem. Finally, ∠JNM is congruent to ∠NMI by the Transitive Property of Equality.
Alternate Interior Angles Theorem
Corresponding Angles Theorem
Vertical Angles Theorem
Same-Side Interior Angles Theorem
Answer:
Alternate Interior Angles Theorem
Step-by-step explanation:
To put it simply; they are both internal angles. N is the internal line and as both JNM and NMI are angles that use the line N both are interior angles. They are clearly on oppisite sides of the line N, making them "Alternate Interior Angles".
Just took the test. :)
The answer is the Alternate Interior Angles Theorem option first is correct.
What are vertically opposite angles?It is defined as the angles when two lines intersect each other and at the intersecting point, some pair of angles are formed which we call vertically opposite angles, as the name describes that they have vertically opposite angles.
The missing figure is attached in the picture please refer to the picture.
We have:
Segment JK is parallel to segment HI while ∠JNM and ∠LNK are vertical angles. ∠JNM and ∠LNK are congruent by the Vertical Angles Theorem
As we know, both angles have internal angles. Since JNM and NMI are angles that both employ the internal line N, they are both interior angles. N is the internal line.
Thus, the answer is the Alternate Interior Angles Theorem option first is correct.

Answer:
?
Step-by-step explanation:
At the end of a card game, James scored −16 points, and Alexis scored −10 points. Enter an inequality in the box to compare the points James and Alexis scored.
Answer:
-16 < -10
-10 > -16
Step-by-step explanation:
James = -16
Alexis = -10
-16 < -10
This means, James scored less than Alexis at the end of the card game
-10 > -16
This means Alexis scored more than James at the end of the card game
The inequality that compares the points Alexis and James scored could either be any of the following:
-16 < -10
-10 > -16
(01.01 MC)Why is 3 + (−5) equal to −2? Because it is 5 units to the left of 0 on a horizontal number line Because it is 5 units to the right of 3 on a horizontal number line Because it is 5 units to the left of 3 on a horizontal number line Because it is 5 units to the right of 0 on a horizontal number line
Answer:
C. Because it is 5 units to the left of 3 on a horizontal number line
Step-by-step explanation:
Directed numbers are numbers which has direction i.e either a negative or positive sign before it. This implies that all numbers are directed, since a number without a sign is taken to be positive.
Thus from the given expression,
3 + (-5) = 3 - 5
= -2
So that,
3 + (-5) = -2
Expressing this on the number line, -2 is 5 units to the left of 3. Thus option C is appropriate.
