Mathematics
1 answer:
Kamila [148]3 years ago
8 0

Answer:

5x^5

y^4

Step-by-step explanation:

-40 ÷ -8 = 5. Then subtract x to the 2nd from x to the 7th, which is x to the 5th. And once you do the same with y, you get y to -4. But since there can't be any negative exponents, you bring that down, giving you the final answer.

Tju [1.3M]

The time take for the cyclist to travel from Fort Worth to Fresno is 90 \ hours

Explanation:

It is given that the distance from Fort Worth to Fresno is 1,530 miles.

The average speed of the cyclist is 17 miles per hour.

The time travelled by the cyclist can be determined using the formula,

Distance=Speed \times Time

Substituting the value of distance and speed, we get,

1530=17\times Time

Dividing both sides by 17, we get,

90 =Time

Thus, the time take for the cyclist to travel from Fort Worth to Fresno is 90 \ hours
