1. 2m = 24

2. y – 9 = 30

3. X = 12
4

4. k + 12.5 = 30

5. 3r = 15.3

see below

Step-by-step explanation:

1. 2m = 24

Divide each side by 2

2m/2 = 24/2

m = 12

2. y – 9 = 30

Add 9 to each side

y-9+9 = 30+9

y = 39

3. X/4 = 12

Multiply each side by 4

x/4*4 = 12*4

x = 48

4. k + 12.5 = 30

Subtract 12.5 from each side

k+12.5-12.5 = 30-12.5

k =17.5

5. 3r = 15.3

Divide by 3

3r/3 = 15.3/3

r =5.1

Hey

Here's your answer:

1. 2m=24

or,m=24/2

m=12

2. y-9=30

or,y=30+9

y=39

3. 3x=12

or,X=12/3

x=4

4. k+12.5=30

or,k=30-12.5

k=17.5

5. 3r=15.3

or,r=15.3/3

r=5.1

Good luck on your assignment

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

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40

the answer would be 150 books

step-by-step explanation:

if you divide 300 by 2 you will get 150
