If you would like to find a step that can be used to find the solution to the set of equations, you can do this using the following steps:

c = 2d + 1
c = 3d + 5
__________
c = c
2d + 1 = 3d + 5
2d - 3d = 5 - 1
- d = 4
d = -4

The correct result would be <span>2d + 1 = 3d + 5.</span>

The answer is C, but I don't understand why- can anyone tell me?

finlep [7]

Answer:

It's C because we are adding a number on the x but here we skip 5 so it's 6, and on y we add 4 up but since we skipped 5 we add 8 and we get 24. 6, 24. You may say "but SpiritBear, 17 plus eight is 25" and that is true, but if you notice the lowest dot actually starts on 5, not 4 making C right.

Hope this helped and wasn't too confusing

If you can answer any of these please do and put the question number by the answer

Free_Kalibri [48]

Answer:

16. a = 13

Step-by-step explanation:

Equation: y = -4(-2) + 5

1) Multiply -4 with -2. Whenever you multiply two negatives, the product turn into a positive number; therefore, -4(-2) = 8

2) Then, add 8 and 5 which is 13.

Hope this helps!

Austin began a repiping job with 26 yards, 2 feet, 5 inches of pipe. When he finished the job, he had 13 yards, 2 feet, 7 inches

My name is Ann [436]

Answer:

<em>He used 12.944... yards of pipe for the repiping job.</em>

Step-by-step explanation:

We know that, 1 yard = 3 feet and 1 feet = 12 inches.

That means, 1 yard = (3×12) inches = 36 inches.

So, 1 feet = $\frac{1}{3}$ yard and 1 inch = $\frac{1}{36}$ yard.

Thus, 26 yards, 2 feet and 5 inches $=(26+\frac{2}{3}+\frac{5}{36}) yards = 26.805... yards$

and 13 yards, 2 feet and 7 inches $=(13+\frac{2}{3}+\frac{7}{36}) yards = 13.861... yards$

So Austin began a repiping job with 26.805... yards of pipe and when he finshed the job, he had 13.861... yards.

So, the length of the pipe he used for the repiping job will be: $(26.805...-13.861...) yards = 12.944... yards$
