Three consecutive integers have a sum of 87. Find the integers.
elena-s [515]

Answer:

28, 29, and 30

Step-by-step explanation:

There's probably better ways but you can estimate by knowing 30*3=90 so it should be somewhere pretty close to 30. Guess and check with basic calculations to get 28, 29, and 30.

Solve for x (30+x)+30+9x=360
UkoKoshka [18]

Answer:

x=30

Step-by-step explanation:

(30+x)+30+9x=360

We move all terms to the left:

(30+x)+30+9x-(360)=0

We add all the numbers together, and all the variables

(x+30)+9x+30-360=0

We add all the numbers together, and all the variables

9x+(x+30)-330=0

We get rid of parentheses

9x+x+30-330=0

We add all the numbers together, and all the variables

10x-300=0

We move all terms containing x to the left, all other terms to the right

10x=300

x=300/10

x=30
