Answer:
a) 4(x - 2) = 100
4x - 8 = 100
4x = 92
x = 23
b) 2(x - 2) = 50
2x - 4 = 50
2x = 46
x = 23
Step-by-step explanation:
When solving for x in both equations, we get the same value of x which makes that statement true.
Answer:
A = 1, B = 2, C = 4, D = 8, E = 16, F = 32, G = 64, H = 128 pennies.
Step-by-step explanation:
Each column has double the previous one.
We're gonna call x the length of the shortest side. The medium side is 3 longer than the shorter side, and the longest side is 14 longer than the shortest (11 + 3 = 14):
Perimeter = shortest side + medium side + longest side
59 = (x) + (x + 3) + (x + 14)
59 = 3x + 17
3x = 42
x = 14
Shortest side = 14
Medium side = 17
Longest side = 28
