that's the solution of the system
Zack would receive $200. You have to make 60% as a decimal= 0.60 then multiply $500*0.60= $300 then you subtract $500-$300=$200
(Hope this works!!)
Answer:
A
Step-by-step explanation:
First, we are already given the sides adjacent and opposite to ∠x. Therefore, we can use the tangent function. Recall that:

The opposite side is 20 while the adjacent side is 14.
Plug in the numbers. Use a calculator:

Answer:
Step-by-step explanation:
1) x-y=18
2) 2x/7-y/4=6
from 1) x=18+y substituting in 2)
2(18+y)/7-y/4=6
36/7+y(2/7-1/4)=6
y=(6-36/7)/(2/7-1/4)
y=(6/7)/(1/28)
y=24
x=18+y=18+24
x=42
