Look at the figure. Find the value of x.
30
90
45
15

15

Step-by-step explanation:

It's an Isosceles triangle meaning both sides are congruent (same)

So with that in mind we can make an equation making them equal to each other to find X.

3x = 5x - 30

Subtract 5x from both sides

-2x = -30

We can't have a negative x so we divide x by a negative

x = 15

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.
