Sue needed to place freshly baked cookies into boxes. Each box can hold one dozen cookies. She wanted to ESTIMATE how many packages she would need to use so that she could get the packages from the storage shelf. She had 249 cookies to package. She used the equation 240 divided by 12 and found that she needed about 20 boxes. What estimation strategy did Sue use? (A) Rounding Strategy (B) Compatible Numbers Strategy (C) Compensation Strategy

The answer is

B. Compatible Numbers Strategy

Step-by-step explanation:

According to learnalberta "The compatible numbers strategy is a method of estimating computations by using "friendly" or "nice" numbers that can be easily calculated mentally. Compatible numbers can be used in estimating sums, differences, products and quotients."

So the closest number to 249 that can be divided by 12 is 240

240/12= 20

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10

f(x)=2/3x+4/3 is the answer because is whose power in the senate is equal to the power of the speaker of the house?
