5y
Another solution is to solve one equation for one variable, and plug that into the other equation.
x + y = 66
x = 66 - y
(66 - y) - y = 18
66 - 2y = 18
-2y = 18 - 66
-2y = -42
-2y/-2 = -42/-2
y = 24
Now that you have y, plug that into the first equation and solve for x.
x + 24 = 66
x = 66 - 24
x = 42
Then plug your two answers into both original equations to verify.
x + y = 66
42 + 24 = 66
66 = 66 check
x - y = 18
42 - 24 = 18
18 = 18 check

Hope this helps.
Step-by-step explanation:
The chosen topic is not meant for use with this type of problem. Try the examples below.
6x2+3y2=126x2+3y2=12 , x+y=2x+y=2
x+2y=4x+2y=4 , x−y=−3x-y=-3
x2−y=2x2-y=2 , 2x−y=−12x-y=-1
-5y + 87 = -18
-5y = -18 - 87
-5y = -180
y = -180 / -5
y = +36
X:
( 5 x 36 ) + 2x = 58
180 + 2x = 58
2x = 58 - 180
2x = -122
x = -122 / 2
x = -61

Deanna knows that the floor in her kitchen is a square with an area of 169 ft2. The perimeter of her kitchen floor is found by adding the lengths of all its sides. What is the perimeter of her kitchen floor? Explain how you found your answer.
Answers
Answer:
52 ft
Step-by-step explanation:
area of a square is l x w. all sides are equal so the l = w
A = 169 ft^2 so each side is the square root of 169 which is 13 ft
perimeter of the floor would be all four sides added or length of 1 side multiplied by 4 since they are all equal
Perimeter = 13ft × 4 = 52 ft
so:
Answer:
52m
Step-by-step explanation:
Area of the square floor = 169 m²
For a square with each side 's' , area will be s². Similarly , for a square with area 'a' , length of each side will be √a.So,
Length of each side of floor = √169 = 13m
For a square with each side 's' , its perimeter will be 4s.Hence ,
Perimeter of the kitchen = 13 × 4 = 52m

Looking at the options , the correct one is C because it shows that the number of pink paints made.
For instance, if we're to make 1 pink paint , we'll need 7 of white paint and 3 cups of red paint.
If we're to make 2 pink paints, we'll need 14 cups of white paint and 6 cups of red paint
if we're to make 3 pink paints, we'll need 21 cups of white paint and 9 cups of red paint and so forth
