16). 15

17). 50

18). 50

19). 53.6

20). 1512

Step-by-step explanation:

9). 45/9 = 5

10). 2 *14² = 2* 196 = 392

11). 5 * 12 * 7 = 60 * 7 = 420

12). 1/2 * 9 * 12 = 54

13).1/2(24)(9 + 21) = 12 * 30 = 360

14). 14 * 13 = 182

15). 16 * 8 * 5 = 640

16). 75/5 = 15

17). 2(5²) = 2 * 25 = 50

18). 8(2.5 + 4.2) = 8 * 6.7 = 53.6

19). 1/2(3)(5 + 6) = 33/2 = 16.5

20). 3.14(6²) = 3.14 * 36 = 113.04

A plumber had a pipe that was 2 yards long he cut 18 inches off the end of the pipe

balandron [24]

To convert yards to feet, you would multiply it by 3. So, since there the pipe is 2 yards long, you could multiply 2*3 to get 6 feet. Then you can convert feet to inches by multiplying it by 12. 6*12 is equal to 72, so 2 yards is equal to 72 inches. Lastly, you can subtract 18 from 72, to get 54, and 54 inches would be your final answer.

-26 times a number minus 22 is equal to 90 less than the number.

IgorLugansk [536]

Answer:

$x = \frac{68}{27}$

Step-by-step explanation:

Let x be the number

Write it out: -26x - 22 = x - 90
Combine like terms: -27x + 68 = 0
Subtract 68 from each side, so it now looks like this: -27x = -68
Divide each side by -27 to cancel out the -27 next to x. It should now look like this: $x = \frac{68}{27}$

I hope this helps!
