Remember, you can do anything to an equation as long as you do it to both sides
but, for inequalities, if you multiply or divide both sides by a negative, you flip the sign


70+5x<30+15x
minus 5x both sides
70<30+10x
minus 30 both sides
40<10x
divide both sides by 10
4<x

x>4 is the solution set

a real world problem could be


company A charges a flat rate of $70 dollars to rent their car and also charge a rate of $5 per mile driven

company B charges a flat rate of $30 dollars to rent the car and also charge $15 per mile

how many miles do you have to drive for you to pay more for company B than A?

An angle measures 148° more than the measure of its supplementary angle. What is the measure of each angle? AND DONT PLAGERISE!!
Usimov [2.4K]

Answer:

Step-by-step explanation:

Supplementary angles add up to 180°.

“θ is 148° more than its supplement”

Supplement of θ = 180°-θ

θ = (180°-θ) + 148°

2θ = 328°

θ = 164°

Supplement of θ = 180°-164° = 16°

Which of the following theorems proves that abc~def?
GaryK [48]

Answer:

D but read below.

Step-by-step explanation:

I take it that the symbol ~ stands for similar. If that is so, then the answer you want is AA, because if 2 angles in a triangle are equal, then all 3 are. So if any 2 equal angles in one triangle are equal to 2 angles in another, then the two triangles are similar.
