3(2x + 2) - 1x - 2 = 39

x=7

Step-by-step explanation:

6x+6-x-2=39

5x+4=39

-4   -4

5x=35/5

x = 7

Step-by-step explanation:

1. Distribute 3 to the what is inside the parenthesis

6x + 6 - x -2 = 39

2. Combine like terms

5x +4 = 39

3. Move the 4 to the same side as the 39

5x = 35

4. Divide both sides by 5

x = 7

she gotta workk that a 2

step-by-step explanation:

delaney would like to make a 5lb nut mixture that is 60% peanuts and 40% almonds.

she has several pounds of peanuts and several pounds of a mixture that is 20% peanuts and 80% almonds.

let 'p' represent the number of pounds of peanuts needed to make the new mixture, and  

let 'm' represent the number of pounds of the 80% almond-20% peanut mixture.

:

p + m = 5

therefore

m = (5-p)

write an equation based on the percent of peanuts

1p + .2m = .6(5)

replace m with (5-p)

p + .2(5-p) = .6(5)

p + 1 - .2p = 3

p - .2p = 3 - 1

.8p = 2

p = 2/.8

p = 2.5 lbs of peanuts required

then

5 - 2.5 = 2.5 lbs of the peanut/almond mixture required

:

a) what is the system that models this situation?

p + m = 5

1p + .2m = .6(5)
