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!

Multiples of 4: 4, 8, 12, 16, 20, 24, 28, 32

A weather station on the top of a mountain reports that the temperature is currently 0°C and has been falling at a constant rate
stich3 [128]

Answer:

-6°C

-15°C

 -1.5°C

Step-by-step explanation:

The computation is shown below:

in one hour the temperature falls by 3°C i.e.

= 0 - 3

= -3°C

In  two hours

= 2 ×  - 3°C

= -6°C

In  five hours

= 5 × -3°C

= -15°C

in half an hour

= 0.5 × -3°C

= -1.5°C
