Answer:
x could be anything. you have to have a equation to solve for x.
Step-by-step explanation:
<span>This problem is an
example of ratio and proportion. A ratio is a comparison between two different
things. For 3:8, it does not coincide with the ratio 40:15. If we try to
multiply 3 by 13, it would not reach 40. Same thing goes for 8 multiplied by
13. For 8:3, if we try to multiply 8 by 5 we would get 40. If we also multiply
3 by 5 we would get 15. Therefore b. is proportional to 40:15. For 90:240, if
we multiply 40 by 2, we would not get 90, also in 15, we would ot get 240. For 120:45,
if we multiply 40 by 3 we get 120. Also, if we multiply 15 by 3 we would get
45. Therefore, d is also proportional to 40:15.</span>
Answer:
in six hours it would be $34.25
Step-by-step explanation:
The computation of the total cost for 6 hours is shown below:
For one hour it would be $8.50
For two hours
= $13.65 - $8.50
= $5.15
For three hours
= $18.80 - $13.65
= $5.15
For four hours
= $23.95 - $18.80
= $5.15
For five hours
= $23.95 + $5.15
= $29.10
For six hours
= $29.10 + $5.15
= $34.25
Hence, in six hours it would be $34.25
Answer:
The other endpoint of the line segment = (-1, -3)
Step-by-step explanation:
A segment has:
Let (x, y) be the other endpoint of the line segment
Therefore, the other endpoint of the line segment = (-1, -3)
Answer:
length = 13 inches
Step-by-step explanation:
let the length be x
hence, the width = x-9
perimeter = 2(x+x-9) = 34
2(2x-9) = 34
4x- 18 = 34
4x = 52
x = 13
