If anyone knows how to do this pls i could really use it

The perimeter of the triangle, namely the sum of all its 3 sides, is 110.

now, the three sides are in a 6:7:9 ratio, namely, if we divide 110 by (6+7+9), it will give us hmmm 110/22, a quotient of 22 equal pieces, namely how many times 22 would go into 110.

now, the small side, takes 6 of those pieces, the medium side takes 7 of them and the largest takes 9 of those pieces.

110/22 = 5

the small side is then 6(5).

the medium side is 7(5).

and the largest side is 9(5).

add them up, and you'd get the perimeter, 110 inches.

step 3 is wrong and the correct answer is -1/3<x (imagine the line under what ever you call the side v)

Step-by-step explanation:

4-6x>-15x+1

minus one over to the other side

3-6x>-15x

add the 6x over

3>-9x

divde

by -9 and flip the side v the other way. Anytime you mulitpluy or divide by a negative number.

-1/3<x
