1. suzette ran and bikes for a total of 110 mi in 7 h. her average running speed was 5 mph and her average biking speed was 20 mph.

let x = total hours suzette ran.
let y = total hours suzette biked.

use substitution to solve for x and y. show your work. check your solution.

note: i genuinely appreciate the . i will be sure to mark brainliest as well. you in advance to all that can !

Finding x.

Suzette ran = x

Suzette biked = 4x

7 = x + 4x --) 7 = 5x --)  1.4 = x

Suzette ran for 1.4 hours

Finding y.

Quickest way is to use Suzette biked = 4x and substitute the x for 1.4 to find how much she biked.

4 x 1.4 = 5.6

1.4 + 5.6 = 7 hours the total time exercising

And the mileage adds up to.

5(1.4) + 20(5.6) = 119

step-by-step explanation:

option: d is the correct answer.

d) none of the above.

step-by-step explanation:

clearly from the figure attached to the question we could see that there is no shape given. hence without any shape given in the figure and after rotation we can't obtained a square pyramid.

since, to obtain a image we need a proper figure of the pre-image so that it can be transformed.

hence, the correct answer is:

d) none of the above.
