Question

Can you help me with 7&8?

Answer 1

Q 7. First=33 Second=35 Third=37

Q 8. First=46 Second=48 Third=50

Explanation:

Question 7. Find three consecutive odd integers whose sum if 105.

Let x=the first number (the smallest number）

Then, x+2=the second number, x+4=the third number

x+(x+2)+(x+4)=105

x+x+2+x+4=105

3x+6=105

3x=99

x=33

First=33 Second=35 Third=37

---------------------------------------------------------------------------

Question 8. The sum of three consecutive even integers is 144. Find the numbers (I think so since you didn't took the whole picture)

Let x=the first number (the smallest number)

Then, x+2=the second number, x+4=the third number

x+(x+2)+(x+4)=144

x+x+2+x+4=144

3x+6=144

3x=138

x=46

First=46 Second=48 Third=50

Hope this helps!! :)
