Substitution. (6 points) 3x + 2y = 11 y = 5x - 1 {show work}

nexus9112 [7]

3x+2y=11
y=5x-1

Substitute the y in the first equation:
3x+2(5x-1)=11
y=5x-1

3x+10x-2=11
y=5x-1

13x=13
y=5x-1

Now substitute the x to find the y:
x=1
y=5-1=4

How tall is the goal post if its shadow is 18ft. The height of the flagpole is 20 ft and its shadow is 8 ft.?

You can set up an inequality to solve this. You can either do big to small --> $\frac{x}{18} = \frac{20}{8}$ or small to big --> $\frac{x}{18} = \frac{8}{20}$ . I'm going to be using big to small because I think it's a little easier.
