Can someone substitute the problem in the picture?

Next time, write down the problem.

y = 5x - 7 -3x - 2y = -12

Creative box:

(5x - 7) - (3x - 2y) = -12

5x - 3x = 2x

(2x - 7) - (2y)

y = -12

2 x -12 = -24

(2x - 7)  (-24) = answer (i'm not sure if its right, because I don't know if that is how the answer was supposed to be written)

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.

a

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
