x+y=14
2x+3y=30
How do I determine which method is used for this and what is it? (Thorough explanation please)
Answer:
x = -18
y = 4
Step-by-step explanation:
x + y = 4
2x + 3y = 30
You can do any math operation to each side of the equal sign as long as you do the same operation to both sides.
change x + y = 4 to x = 4 - y
Now substitute (4 - y) into the second equation, in place of x.
2(4-y) + 3y = 30
multiply the 2(4-y) part:
8 -2y + 3y = 30
simplify:
8 + y = 30
subtract 8 from each side:
y = 22
now substitute the value of y back into the first equation to solve for x:
x + 22 = 4
subtract 22 from both sides:
x = -18
Check:
x + y = 4
22 -18 = 4
4 = 4 (this checks)
2(-18) + 3(22) = 30
-36 + 66 = 30
30 =30 (this checks also)
PS: you could have solved for y first if you had wanted to. The results would be the same.

Step-by-step explanation:
The function is f of x
Substitute 0 for x
the equations hould now be
f(0) = (0 + 5)(0 - 1)
Combine like terms: f(0) = (5)(-1)
Multiply 5 and -1 to get -5

Find the circumference and the area of a circle with radius 6 km.
Write your answers in terms of it, and be sure to include the correct units in your answers.
Answer:
Circumference: 12pi or 37.7
Area: 36pi or 113.1
Step-by-step explanation:
C = 2(pi)r
C = 2 * pi * 6
C = 12pi or 37.7
A = (pi)r^2
A = pi * 6^2
A = 36pi or 113.1
what the answer please
Answer:

How many square inches are in 60 square feet?
5 square inches
72 square inches
720 square inches
8,640 square inches
Answer:
8,640
Step-by-step explanation:
One foot is 12 inches, so a square foot would be 144 inches (12×12 -> l×w) So, you would multiply 60 by 144, and you would get 8,640 square inches.

Help me please I am
so confused
Answer:
Step-by-step explanation:
The midpoint between two points is the average of the coordinates.
mp=((x2+x1)/2, (y2+y1)/2)
In this case we are given one end point and the midpoint.
Just look at the x coordinate first.
If the mid x is 8 and the x from j is 10 we have
(10+x)/2=8
10+x=16
x=6, now for the y for j when y=6 and mid y of 5
(6+y)/2=5
6+y=10
y=4
So the coordinates of K are (6,4)
a fraction equivalent to 0.5

if x^3 = 216, what is the value of x?
3
4
6
9
Answer:
6
Step-by-step explanation:
i just cubed all of the numbers given and gotten that 6^3=216
Answer:
x=6
Step-by-step explanation:
If you would like to know the value of x, you can calculate this using the following steps:
x^3 = 216
x = sqrt3(216)
x = 6
The correct result would be 6.
(x + 3)^2-1=35
Create a list of steps
Answer:
Step-by-step explanation:
(X + 3) ( x + 3) is x^2 + 3x + 9
-1 is now 8
X^2 + 3x + 8 = 35
Subtract 8 from both sides so it now equals 27
Divide everything by 3 so its now
X^2 + x = 9 use quadratic formula and get x = -3.541 and 2.541

NEED HELP THIS IS MY LAST QUESTION (WRONG ANSWERS GET BLOCKED)
The greatest number of bags she can make without having any stickers or pencils left over is 18 bags.
Step-by-step explanation:
The best way to go about this is by dividing the total number of pencils and stickers by the answer choices given and starting with the highest number (27). We already know that 27 goes into 54 twice without anything left over, but can only go into 36 once while having 9 leftover. This would eliminate 27 as an answer choice as it does not meet the criteria.
Repeat the same process with 18, so 54 divided by 18 is 3, and 36 divided by 18 is 2. There is nothing left over, every bag will have an equal number of pencils and stickers. With this answer, the question criteria is true, making this the correct answer choice.
