Answer:
The second set of equations is the one you want.
Step-by-step explanation:
If s is the cost of a shirt and you buy 3 of them, you represent that as 3s. Likewise with all the other numbers of articles of clothing you are given. The first situation then is 3s + 5t = 60. The second situation is 2s + 3t = 39.
It's choice two. When you are putting the equation into y=mx+b form you have to subtract the 3x and put it onto the same side as 10. Then you would have 2y=-3x+10 then divide everything by 2 to have y be alone. Then it would be y=-3/2x+5 giving you the slope of the line being -3/2
Well, the diameter doesn't matter in this problem because we allready know how fast, and how much the pool is filling. So, 6 inches is half of a foot, because 1 foot = 12 inches, and six is half of 12. If it take 1 hour for the pool to fill 1/2 of an foot, than it takes 2 hours for a full foot. Next, we multiply 2 hours, by 1 foot, and convert the 1 foot, to 4 feet. Which means to figure out the number of hours, we have to times 2 hours by 4 feet. And that is 8.
So the answer is: 8 feet.

The correct answer is option C: 8
Step-by-step explanation:
We will use the mid-segment theorem of triangle to solve this problem.
We can see that the line which is represented by 2x-9 is the mid-segment of the triangle as it passes from mid-points of two sides of the triangle
The mid-segment theorem states that "Any line that passes through the mid-points of two sides of triangle is parallel to the third side and in length, it is half the length of the third side
In the given figure,
The length of line represented by 2x-9 will be half of 14
So,
Adding 9 on both sides
Dividing both sides by 2
Hence,
The correct answer is option C: 8
