I will give brainliest Answer two questions about equations A and B:

A. x/4+1=-3

B. x+4=-12

1) how can we get equation B from equation A?

choose 1

(Choice A) rewrite one side (or both) using the distributive property

(Choice B) rewrite one side (or both) by combining like terms

(Choice C) multiply/divide only one side by a non zero constant

(Choice D) multiply/divide both sides by the same non zero constant

2) based on the previous answer ,are the equations equivalent? in other words ,do they have the same solution?

choose 1

(Choice A) yes

(Choice B) no

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm

step-by-step explanation:

t hope this

:

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)
