Answer:
11 cm, 19 cm, 27 cm
Step-by-step explanation:
Triangles have 3 sides and perimeter is the sum of all side lengths. So the equation is x + (2x-3) + (2x+5) = 57.
x + (2x-3) + (2x+5) = 57
x + 2x - 3 + 2x + 5 = 57
x + 2x + 2x - 3 + 5 = 57
5x + 2 = 57
5x = 57 -2
5x = 55
x = 11
Now that we know the value of x, we can figure out the side lengths. The first side (x) is 11 cm long, the second side (2x - 3) is 19 cm, and the third side (2x + 5) is 27 cm long.
15.50 x 20 = $310
31 x 8 = $248
310 + 248 = $558
Her total pay for the week is $558.
