Answer:
14.x=-2
21. x=-2
23. x=5
7.x=12
2.x=49
Step-by-step explanation:
I got your back bro:
14. Subtract 7 on both sides. Then divide -16 by 8. x=-2
21. Add 1 on both sides. Divide 18 by -9. x=-2
23. Subtract 24 on both sides, then divide -25 by -5. your answer is x=5.
7. Add 2/5 on both sides. then multiply 2 2/5 by the reciprocal of -1/5. Your answer is x=12
2. Subtract 5 on both sides. Multiply 14 by the reciprocal of 2/7, or 7/2. Your answer is 49.
Good luck!
Answer:92.4
Step-by-step explanation:
4x+7x=132
10x=132
x=132/10
x=13.2
4x=4×13.2
=52.8
5x=7×13.2
=92.4
46/287.5 = .16
.16x287.5 = 46
The answer is 16%
-4*3 1/4 would be and expression you can use
