1.37x + 1.08y = 16.36
x + y = 13
x = 13 - y
1.37* (13-y) + 1.08y = 16.36
17.81 - 1.37y + 1.08y = 16.36
1.08y - 1.37y = 16.36 - 17.81
-0.29y = -1.45
y = 5
x + 5 = 13
x = 13-5
x = 8

Step-by-step explanation:
Answer:
where is figure by the way
Answer:
a.
Step-by-step explanation:
Volume of square = length³
64 = length ³
Taking cube root in both sides
We'll get
Length = 4
Now perimeter of square = 4×L
= 4×4
= 16
Nonmembers: $10 per hour = 10h
Members: $300 and $4 per hour = 300 + 4h
10h > 300 + 4h
6h > 300
h > 50
You'd need to use it for more than 50 hours.
