Q:

PLEASE HELP WITH MATH!!!!!!! 60 points and brainliest!!!!!!1. Solve the inequality 5x < 16 + x.x < 1/4x > 1/4 x < 4x > 4 (not the answer)2. Solve the inequality 12x < 22 + x.x < 1/2x > 1/2 (not the answer)x < 2x > 23. Solve the inequality -8x - 10 > 7x + 20.x < - 30x > - 2x > - 30 (not the answer)x < - 24. Solve the inequality 13x - 4 < 12x - 1.x < 3x > 3x < 5 (not the answer)x > 55. Solve the inequality 3 - 5(2x + 1) 10.(picture below!!!) but it's not the answer I selected. 6. Solve the inequality 7(x - 2) < -5.x < 9/7x > 9/7x < -9/7x > -9/7

Accepted Solution

A:
1. subtract over the x on the right side of the inequality so you get 4x<16  divide 4 over to get x alone the inequality turns into x<4.
2. subtract over the x on the right side so you get 11x<22 divide over 11 to get x<2 
3. Add over 10 to get -8x>7x+30 subtract over 7x to get -15x>30 divide by -15 to get x<-2 make sure to flip over the sign since you're dividing by a negative 
4. Add over the 4 to get 13x<12x+3 subtract over 12 and get x<3
5. I can't solve five since their is no inequality sign, the answers show it both ways so i need a starting one to go off on but it is either A or B just flip over the original sign and that will be the answer .
6. Distribute the 7 to get 7x-14<-5 add over the 14 and get 7x<9 divide over the 7 and get x<9/7
