Plug in for x.
7(2y - 4) + 5y = -66
14y - 28 + 5y = -66
19y - 28 = -66
19y = -38
y = -2
Put it back into the equation.
2(-2) - 4 = -8
x = -8
The x-value is x = -8
Answer:
x = 50
GI = 72
ET = 56
Step-by-step explanation:
Corresponding sides of similar triangles PIG and LET are proportional.
__
GI/PI = ET/LT . . . . . . . . . corresponding sides are proportional
(x +22)/9 = (x +6)/7 . . . . . using the given values in the proportion
7(x +22) = 9(x +6) . . . . . . . cross multiply
7x +154 = 9x +54 . . . . eliminate parentheses
100 = 2x . . . . . . . . . subtract 7x+54
50 = x . . . . . . . . divide by 2
GI = x +22 = 50 +22 = 72
ET = x +6 = 50 +6 = 56
1/4= 2/8
3/8 + 2/8 = 5/8
Therefore, 3/8 of the playground is left for the swings and play equipment
Answer:
54
Step-by-step explanation:
2x+2=3x-52
-2x -2x
2=x-52
+52 +52
54=x
