Translate the sentence into an inequality.
The sum of 3 and c is less than -29.

3+c < -29 or c+3 < -29 because of communitive property

Step-by-step explanation:

First, the sum means addition, you could write 3+c or c+3 because addition is communitive property.

Then the sum is less than -29 so we need to use the less than symbol which is this symbol: <  

Now write the inequality! 3+c < -29

3 + c < -29

Step-by-step explanation:

3 + c < -29 from "The sum of 3 and c is less than -29."

3 + c < -29 from "The sum of 3 and c is less than -29."

3 + c < -29 from "The sum of 3 and c is less than -29."

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

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.
