I'd really appreciate the on this question! i'll give the brainliest! mike and beth are saving money to go to disney world. they need at least $1975 in order to go. mike mows yards and beth will wash cars to raise money. mike charges $25 each time he mows a yard and beth charges $15 for each car she washes. the number of cars that beth wash is no more than four times the number of lawns mike has scheduled to mow. beth will wash at least 50 cars. write a set of constraints to model the problem, with x representing the number of lawns mowed and y representing the number of dogs walked.

We will first define variables

Let Mike be M and Beth be B.

First inequality is 25M + 15B ≥ 1975 an the second is  B≤ 4M

When we replace B in the first inequality we get

25M + 15*4M ≥ 1975 => 25M + 60M ≥ 1975 => 85M ≥ 1975 =>

M ≥ 1975/85 => M ≥ 23.23 => M= 24

When we replace value for M in the second inequality we get

B ≤ 4*24 => B ≤ 96

We will check   25 * 24 + 15 * 96 = 600 + 1440 = 2040$ ≥ 1975$

That is correct!

If we accept M= 23 then B≤ 92

We will check again 25*23 + 15*92 = 575 + 1380 = 1955$ ≤ 1975$

That is incorrect!

Good luck!!!

3x + 18 = 147°

step-by-step explanation:

3x + 18 = 147°, because the value of the central angle is equal to the value of the arc formed by it.
