Answer:
$80
Step-by-step explanation:
10x + 30 = y
He wants to rent it for 5 hours, so we replace x with 5.
10(5) + 30 = 80
He should expect to pay $80 for the rental.
Answer:
X=2
Step-by-step explanation:
y= 2x- 3
1/2x= 2x-3
1/2x-2x= -3
x-4x= 2*-3
-3x=-6
x=2
Well how much money does he get from mowing a lawn? Divide 190 by that amount.
Answer: X = kuv/ (u+v)
that means that x(u+v)/(uv) = k, a constant. so you want x such that,
x(3+3)/(3*3) = 3(3+1)/(3*1)
x=6
