Phil is riding his bike. he rides 23 miles in 2 hours, 34.5 miles in 3 hours, and 46 miles in 4 hours. find the constant of proportionality and write an equation to describe the situation. let x represent the number of hours.

the equation that describes the relationship is y =
i need

Constant = 11.5

y = 11.5x.

Step-by-step explanation:

This is direct variation so the equation of proportionality is

y = kx where y = miles, x = hours and  k is a constant.

23 =  2k

k = 11.5

34.5 = 3k

k = 11.5

46 = 4k

k = 11.5

The equation is my= 11.5x.

after 1 year: 221 deer

step-by-step explanation:

30% of 170 is 51. 170+51=221

we can't see all full 4 options, but if this is the full option, than the very left one is correct:

-2/5 * -3 3/4

remake the question, adding a picture of all the question, or write down the full left and right answers.
