Which represents the solution set of 5(x+5)< 85?

x< 12
x> 12
x< 16
x> 16

The answer is: x<12

Steps by steps

5(x+5)<85

Divide each term by 5 and simplify.

5(x+5)÷5<85÷5

Reduce the expression by cancelling the common factors.

x+5<85÷5

Divide 85 by 5.

x+5<17

Move all terms NOT containing "x" to the right side of the inequality.

Subtract 5 from both sides of the inequality.

x<-5+17

Add -5 and 17.

=x<12

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)
