PLEASE HELP ME!!!!! I'LL MARK YOU BRAINLIEST IF YOU ANSWER THIS CORRECTLY!
Lubov Fominskaja [6]

Answer:

x = 5

Step-by-step explanation:

The sum of interior angles in a triangle is 180°

91° + 10x - 4° + 8x + 3° = 180° add the like terms

90° + 18x = 180°

18x = 180° - 90

18x = 90° divide both sides by 18

x = 5

Which of the following inequalities are correct?
Natali5045456 [20]

Answer:

A and B

Step-by-step explanation:

- 3/5 is less than -1/5 because it is farther away from 0 on a number line (also, when it comes to figure out which inequality is true with negative number, the smaller one is going to be greater because it is closer to 0 on a number line)

3/5 is greater than 1/5 because they are both positive and 3/5 is the bigger number

-1/5 is not less than -3/5 because if A is true, than this cannot be true because it is saying the exact opposite.
