Lets say we represent the amount of time she could ski.
So it would be x = the amount of time she skis
And 5x would represent how long it took her to climb
and she took 9 minutes to climb.
So what we would do first is put it in a equation like this
x + 5x = 9
Now we have 6x = 9
Divide 9 by 6x, and we get x = 15
So multiply 1.5 by 5 and the answer would be 7.5
Hopefully this helped. :)
2x+3=13
2x+1=x+4
x-5=x.0.5
3x+4=4x-3
Answer:
C. 14%
Step-by-step explanation:
We know that Dallas's wage increased from $9 to $10.25.
Let's say the percent increase is x. Then we write the expression:
9 + x * 9 = 10.25
Divide by 9 from both sides:
1 + x = 10.25 / 9 ≈ 1.14
Subtract 1 from both sides:
x = 1.14 - 1 = 0.14
Since x is a percent, that means x = k/100, where k is an integer. So we have:
x = k/100 = 0.14
Multiply both sides by 100:
k = 0.14 * 100 = 14%
The answer is thus C.
