Answer:
Q 7. First=33 Second=35 Third=37
Q 8. First=46 Second=48 Third=50
Step-by-step 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!! :)
