Question

Please help! i’m struggling in math so much!

Answer 1

Question 2 ⇒ 95 calories

Question 3 ⇒ 40,933 logins

Explanation:

Question 2.

Given:

The given equation is

`y=30x+5`-----------------------(1)

Where x = number of laps

And y = calories burned

The student walked 3 laps.

The calories would be burn after they walked 3 laps, so we substitute
`x = 3` in equation 1.

`y=30* 3+5`

`y=90+5`

`y=95`

Therefore 95 calories would be burn if walked 3 laps.

Question 3.

The given equation is

`y=-1067x+58005`---------------------(1)

Where x = temperature

And y = number of logins

temperature is given, so we put x = 16 in equation 1.

`y=-1067* 16+58005`

`y=-17072+58005`

`y=40933`

Therefore the outside temperature is 16° after 40,933 logins.
