Answer:

Both, the methods will give the correct answer.

Step-by-step explanation:

We are given the following information in the question:

178 - 135 = 43

If Carmine adds 5 to each number, then,

(178 + 5) - ( 135 + 5) = 183 - 140 = 43

If Karen adds 2 to each number than the subtraction problem will look like:

(178 + 2) - ( 135 + 2) = 180 - 137 = 43

Adding 5 to each number or adding 2 to each number won't change the answer.

One must make sure that equal amount of quantity should be added to both the components. Sometimes this technique helps us to simplify the problem and it could be solved easily.

Answer:

Yes

Step-by-step explanation:

Since the same value, x, is being added to both numbers they are subtracting the answer won't be changed.

178-135=43

183-140=43

180-137=43

20 POINTS PLEASE HELP ME!!!
Minchanka [31]

Answer:

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
