176.3- 15.75

I have that same question on my extra credit!

Step-by-step explanation:

I know the answer its 160.55 but I don't know what i should do for the problem. This is my questions:

Mina asked four friends to explain how each one solved the expression . Here are their explanations Please comment if these are the same:

Ivy’s explanation: I lined up the numbers to subtract.

 176.3

- 15.75

 18.8

Hannah’s explanation: I lined up the two decimals according to place value. I put a 0 in the hundredths place to make it easier for me to subtract.

 176.30

- 15.75_

 161.45

Jose’s explanation: I lined up the two decimals according to place value.

176.3

- 15.75

 161.45

An’s explanation: I counted up from 15.75 to 176.3 to find the difference. I underlined each number I added on each line.

15.75 + 0.25 = 16

16 + 4 = 20

20 + 150 = 170

170 + 6 = 176

176 + 0.3 = 176.3

I rearranged the underlined numbers to make them easier to add: .

150 + 6 + 3 + 0.25 = 163.25

Explain each student’s mistake and solve the problem correctly.

Show your work.

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

6/20
