Answer:
x = 4
Step-by-step explanation:
Isolate the x:
13x + 7 = 8x + 27
subtract 7 from both sides:
13x = 8x + 20
subtract 8x from both sides:
5x = 20
divide both sides by 5:
x = 4
I believe the shadow is 2 ft taller form my understanding
2x + By = 15
We solve for y to put the equationj in the y = mx + b form in which b is the y-intercept.
By = -2x + 15
y = -2/Bx + 15/B
The y-intercept is 15/B, and we are told the y-intercept is 5.
15/B = 5
15 = 5B
B = 3
