Answer:
x = -2.585
Step-by-step explanation:
You will have to plug this into your graphing calculator.
In y=, type 5(1/2)^x in the Y1 and type 30 in Y2.
When you hit 2nd trace and hit find intersections, you will get (-2.585, 30).
The answer is x = -2.585
I think the answer is 32x
They added it wrong. They added it like this:

When it shouldve been this:

They just added a place marker in all numbers below 100.
1. S= squash
Z= zucchini
5s + 2z = 1.32
3s + 1z = 0.75. -2 ( 3s + 1z = 0.75)
5s + 2z = 1.32
-6s - 2z = -1.50
-s = -0.12
Squash = 0.12
5s + 2z = 1.32
5(.12) + 2z = 1.32
.60 + 2z = 1.32
2z = 1.32-.60
2z/2 =.72/2
Z= 0.36
