Answer:
1. B
2. A
Step-by-step explanation:
I've done this before, very easy.
The cost of each of the 15 tubes given a total cost of tubes to be $277.50 is $18.50
Given:
Total cost of rubes = $277.50
Total number of tubes = 15
<em>Cost of each tube = Total cost of rubes / Total number of tubes</em>
= $277.50 / 15
= $18.50
Therefore, the cost of each of the 15 tubes given a total cost of tubes to be $277.50 is $18.50

If u multiply the first equation by -4, u get -2x - y = -20
and when u add the 2 equations..
-2x - y = -20
2x + 3/8y = 5
-----------------
0 - 5/8y = -15.....u notice that the x terms r eliminated.
The circumference is 72.22. The formula for circumference is the diameter times pi, which in this case multiplies to about 72.22
So in order to determine the factors of the given expression above, here is the step by step process.
Firstly, we need to know the factors of -8 that when multiplied together will result it -8. So after, I have listed it, I found out that it is -2 and +4.
So let us check. So the factors for this would be (3x-2)(x+4). When you multiply these factors, the result would be <span>3x2 + 10x - 8. Hope this answer helps.</span>
