Answer:
6 hours
Step-by-step explanation:
The equation for this would be
c=3h+12
It costs $3 per hour, and there is a $12 cost no matter how many hours the bike is rented for
We know,c, or the cost is $30, so we can substitute that in
30=3h+12
Solve, by isolating the variable,h
First, subtract 12 on both sides
30=3h+12
18=3h
Divide by 3 on both sides
h=6
So, she rented the bike for 6 hours
48 is 80% of 60
48 of 60 can be written as 48/60
Multiply both the numerator and the denominator by 100
48/60 · 100/100 = 80/100 = .8 = 80%
If you are using a calculator, simply enter 48 ÷ 60 · 100 which will give you 80 as the answer.
Answer:
84
Step-by-step explanation:
140% of 60 = 60 times 140% = 60 × 1.4 = 84

Answer:
Step-by-step explanation:
∠ABC = ∠BCD { AB // CD; BC TRAVERSAL, alternate angles are equal}
∠ABC = 20
∠BCA = ∠BAC {angles opposite to equal sides are equal}
∠BCA = ∠BAC = x
x + x + 20 = 180
2x = 180 - 20
2x = 160
x = 160/2
x = 80
