Three times the sum of nine and a number is at most -9

Step-by-step explanation:

I assume the question is "what is x"

Let x be the number.

At most means less than or equal to.

3(9+x)<-9

Distribute: 3*9+3*x<-9

27+3x< -9

Subtract 27

3x< -36

Divide by 3

x< -12

x=17

step-by-step explanation:

solve 3x-24=x+10

then that makes it 2x=34 because you subtract an x from both sides to get rid of the one on the right, and then you add 24 to both sides to get rid of the 24 on the left

divide by both sides by 2 to get your answer so that you can get your answer

step-by-step explanation:

square root means have of a number so have of 3 is 1.5 then multiply it by 8 and you get your answer!
