20 points ! solve each equation or inequality (show your work) first problem: 4(3p + 6 ) = 12 second problem: -5(x -4) = -30 third problem: -3m + 15 > -6

p = -1

x=10

m < 7

Step-by-step explanation:

4(3p + 6 ) = 12

Distribute the 4

12p +24 = 12

Subtract 24 from each side

12p+24-24 = 12-24

12p = -12

Divide by 12

12p/12 = -12/12

p = -1

-5(x -4) = -30

Distribute the -5

-5x+20 = -30

Subtract 20 from each side

-5x+20-20 = -30-20

-5x=-50

Divide by -5

-5x/-5 = -50/-5

x=10

-3m + 15 > -6

Subtract 15 from each side

-3m + 15-15 > -6-15

-3m >-21

Divide by -3   remember to flip the inequality

-3m/-3 < -21/-3

m < 7

step-by-step explanation:

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls
