Kevin is making a picture frame. He has a piece of trim that is 4 feet long.How many 14−inch-long pieces can Kevin cut from the trim?How much of a foot will he have left over?

Answers

First, convert 4 feet into inches - 48 inches. Then, divide 48 by 14 to get 3.43, so he can have 3 14-inch long pieces. To get the left over out of a foot, take 14 x 3 to get 42, then subtract 42 from your original 48 inches to get 6 inches left, which is half of a foot.

Answer:

3 pieces and 1/2 of a foot

Step-by-step explanation:

1. 4 feet converts to 48 inches. (4 X 12)

2. 48 inches divided by 14 can make three pieces

14+14+14=42 inches.

3. You will have 6 inches left over, and 6/12 is half of a foot :)

explain how to solve for the missing side from the similar figures given and solve. (do not just give the answer)

Answers

Answer:

x=14

Step-by-step explanation:

Since the triangles are similar, you first line up the sides. Then, because the 16 and the 24 line up together, you divide them to find out how much bigger the first triangle is, which is 3/2 or 1.5. After that, you can see that the 21 and the x are on the same side, so you would divide 21 by 1.5 or 3/2 to get x. 21÷1.5=14.

x=14

Answer: X= 14

Step-by-step explanation: line AC equals 21 and line BC equals 24, i put 24 over 21 like a fraction then i look at the smaller triangle now EF is proportionate too BC so next to the 24 i put 16 and line DF is X so you put X underneath 16 and next too 21. now you cross multiply and divide leaving you with 14 so line DF or X is 14

I think we need more information on what topic you are on in algebra at the moment. But my best guess would be to solve for x, and then place your answers on the x-axis. This would be questionable though, because you would get many 0=(some number), which would be answered as untrue. Question numbers 4, 6, and 9 would all be untrue. Other than that,
1) x = 1
2) x = -2
3) x = 0
4) 0 = -3 (untrue)
5) x = -1
6) 0 = -8 (untrue)
7) x = -3/2
8) x = 0
9) 0 = -1 (untrue)
