Answer:
From the above we can roughly for an equation which is:
58.50 = Bill - (10% x Bill)
58.5 = Bill - (1/10 x Bill)
58.5 = 9/10 x Bill (Divide both sides by 9/10)
We get:
Bill = 58.5 / (9/10)
Bill = 65
Original bill is $65.
Me : 4 x + 8 y = 64
My friend: 8 x + 16 y = 128
A ) 4 * 4 + 8 y = 64
16 + 8 y = 64
8 y = 64 - 16
8 y = 48
y = 48 : 8
y = 6 ( me and my friend work 6 hours at the second job )
B ) The number of hours we each work at the first job are also the same.
The value of y varies directly with x, so
We have:
Answer A)
Answer:
I believe the answer would be C.
Step-by-step explanation:
This is because after plugging in the numbers (2 in replace of x) (-9 in replace of y) for the problem -2y- 6x =6... the statement was determined true.... so, therefore, I believe the correct answer is C
