Quickly ! solve for x. x+23=−22
enter your answer in the box.
x = _?

x=-45

Step-by-step explanation:

x+23=−22

To get x alone, we need to solve for x

To isolate x  , remove the number attached with x

To remove any number we do opposite operation

Here +23 is with x, to remove +23 we subtract 23 on both sides

x+ 23 = -22

  - 23     -23

x = -22 - 23 = -45

So the value of x= -45

answer: this is not a question

step-by-step explanation: this is a answer

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)
