Answer:
$104 For 8 Hours
Step-by-step explanation:
First figure out the rate for one hour. To figure this out divide $39 by 3. This equals $13. Which means it costs $13 to rent the surfboard for one hour. Finally multiply $13 by 8. This equals $104. Meaning it costs $104 to rent the surfboard for 8 hours.
Answer:
A = 9/100
B = -[1/100]
C = -[39/100]
Step-by-step explanation:
Given:
0.09x - 0.01y = 0.39
Find:
A,B,C
Computation:
Linear equation;
Ax + By + C = 0
So,
0.09x - 0.01y = 0.39
9x/100 - 1y/100 = 39/100
9x/100 - 1y/100 - 39/100= 0
So,
A = 9/100
B = -[1/100]
C = -[39/100]
