Answer is 150/x see photo for solution
Answer:
63in
Step-by-step explanation:
You add 5in plus 4in since they are both on the same side which would equal 9, then you go to the bottom and add 5in plus 2in which equals 7in, then you use the formula for area which is length times width and you get 63in.
Answer:
171 degrees
Step-by-step explanation:
x + 9 = 180
x = 171
Solving:
-7 + y = 3 + 2y
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Add '-2y' to each side of the equation.
-7 + y + -2y = 3 + 2y + -2y
Combine like terms: y + -2y = -1y
-7 + -1y = 3 + 2y + -2y
Combine like terms: 2y + -2y = 0
-7 + -1y = 3 + 0
-7 + -1y = 3
Add '7' to each side of the equation.
-7 + 7 + -1y = 3 + 7
Combine like terms: -7 + 7 = 0
0 + -1y = 3 + 7
-1y = 3 + 7
Combine like terms: 3 + 7 = 10
-1y = 10
Divide each side by '-1'.
y = -10
Hope it helps. (:
