John sells candy bars for 2$ each. How much will he make if he sells 10 bars
Each Candy Bar is $2, so if he sells 10, you just need to multiply,
10 * $2 = 20
So He'll make $20, selling 10 bars.
If he sells 50 bars then just multiply,
50 * $2 = 100
So He'll make $100 selling 50 bars.
Answer:
he will make $20 dallors
10×$2=20

Determine whether the sequence is arithmetic. If it is, determine the common difference.
--12, 10, 32, 54,...
Answer:
The sequence is arithmetic
Step-by-step explanation:
Here we want to determine the sequence is arithmetic
If the sequence was arithmetic, the difference between the terms would be constant
We have this as;
10-(-12) = 22
32-10 = 22
54-32 = 22
As we can see, the difference is constant and so we have it that the sequence is arithmetic

Answer:
exact form:
-111/8
Decimal form:
-13.875
Mixed Number Form:
-13 7/8
Answer:
-5.875
Step-by-step explanation:

y se multiplica por el -6
0.25x-6= -1.5
luego se resuelve el otro lado
primero dividimos
5/8=0.625
y se multiplica por -7
0.625x-7= -4.375
y para finalizar se suman los dos lados
-4.375 + -1.5
= -5.875

b=2x^2(x-5) divided by 10x solve b if x=10
Answer:
answer is 10
Step-by-step explanation:
2x^2(x-5) /10x
x=10
so,
=2*10^2 (10-5) / 10*10
=2*100(10-5) /100
=200*5 / 100
=1000/100
=10

What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
b = 2x² (x - 5) ÷ 10x
When x = 10 find b.
Now,
b = (2x² (x - 5))/ 10x
Substitute x = 10
b = 2 x 10² ( 10 - 5) / 10 x 10
b = 200 x 5 / 100
b = 10
Thus,
The value of b when x = 10 is 10.

Graph the equations
Y=400+50x
Y=300+25x
1.) from the graph at what time will the they have the same height
I’ll give u brainlist pls help
Answer:
We conclude that, at 4 minutes, both will have the same height which is 200 feet.
Step-by-step explanation:
Given the system of equations
[tex]y=400+50x[/tex]
[tex]y=300+25x[/tex]
Important Tip:
The point of intersection of the two lines would give us the point at which both have the same height.Graphing the system of equations
The graph of the equation y = 400 + 50x
First, determine the y-intercept of the equation y = 400 + 50x by substituting x = 0
[tex]y = 400 + 50x[/tex]
[tex]y = 400 + 50(0)[/tex]
[tex]y = 400 + 0[/tex]
[tex]y = 400[/tex]
Thus, we determine that the ordered pair (0, 400) represents the y-intercept of the equation y = 400 + 50x.
Next, determine the x-intercept of the graph of the equation y = 400 + 50x by substituting y = 0
[tex]y = 400 + 50x[/tex]
[tex]0=400+50x[/tex]
switch sides
[tex]400+50x=0[/tex]
Subtract 400 from both sides
[tex]400+50x-400=0-400[/tex]
Simplify
[tex]50x=-400[/tex]
Divide both sides by 50
[tex]\frac{50x}{50}=\frac{-400}{50}[/tex]
Simplify
[tex]x=-8[/tex]
Thus, we determine that the ordered pair (-8, 0) represents the x-intercept of the equation y = 400 + 50x.
Important Tip:
The point at which the graph crosses the y-axis is called the y-intercept. The point at which the graph crosses the x-axis is called the x-intercept.The red graph on the diagram represents the equation y = 400 + 50x having the y-intercept (0, 400) and x-intercept (-8, 0)
Please check the attached diagram.
The graph of the equation y = 300 + 25x
Now, determine the y-intercept of the equation y = 300 + 25x by substituting x = 0
[tex]y = 300 + 25x[/tex]
[tex]y = 300 + 25(0)[/tex]
[tex]y = 300 + 0[/tex]
[tex]y = 300[/tex]
Thus, we determine that the ordered pair (0, 300) represents the y-intercept of the equation y = 300 + 25x.
Next, determine the x-intercept of the graph of the equation y = 300 + 25x by substituting y = 0
[tex]y=300+25x[/tex]
[tex]0 = 300 + 25x[/tex]
switch sides
[tex]300+25x=0[/tex]
Subtract 300 from both sides
[tex]300+25x-300=0-300[/tex]
Simplify
[tex]25x=-300[/tex]
Divide both sides by 25
[tex]\frac{25x}{25}=\frac{-300}{25}[/tex]
Simplify
[tex]x=-12[/tex]
Thus, we determine that the ordered pair (-12, 0) represents the x-intercept of the equation y = 300 + 25x.
The blue graph on the diagram represents the equation y = 300 + 25x having the y-intercept (0, 300) and x-intercept (-12, 0)
Please check the attached diagram.
Analyze the POINT OF INTERSECTION:
As we already know that the point of intersection of the two lines would give us the point at which both have the same height.
The diagram indicates that:
at x = -4, the value of y = 200.
It is the point where both lines meet.
Thus, the point of intersection of the two lines is:
(x, y) = (-4, 200)
Conclusion:
As x represents the time in minutes and y represents the height in feet.
Thus, we conclude that at x = 4 minutes, both will have the same height i.e. y = 200 feet
Therefore, we conclude that, at 4 minutes, both will have the same height which is 200 feet.
What expression is equivalent to 9(3x + 8)? *
Step-by-step explanation:
This is what it is equal to:
9×3x=27x
9×8=72
Therefore it will be:
[tex]27x + 72[/tex]
hope it helps!
Answer:
27x+72
Step-by-step explanation:
You have to use the distributive property to simplify the expression. Therefore, you have to multiply both terms inside the parentheses.
1. 9*3x=27x
2. 9*8=72
They could not be added together, as they are not like-terms. So, you just write it down as 27x+72.

What's the number that is halfway between numbers 0 and 121?
Halfway Between 0 and 121
Halfway Between
When you ask "What number is halfway between 0 and 121?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=0 and Y=121.
Halfway Between Line
To find the number halfway between 0 and 121, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 0 and 121 into our formula, we get:
(0 + 121)/2 = 60.5
Thus, the number halfway between 0 and 121 is 60.5
Answer:
solution given;
half way between 0 and 121=?
let a=0
and
b=121
we have
halfway =[a+b]/2=[0+121]/2=60.5
half way between 0 and 121 is 60.5
