Answer:

7 ft 9 inches

Step-by-step explanation:

3 ft 9 in + 4 ft = 7 ft 9 inches

All you have to do is add the feet with the feet and add the inches with the inches. They want you to add 3 ft + 4 ft, which is 7 ft. There are no inches to add to 9 in, so that just remains 9 in.

Therefore, your answer is 7 ft 9 in.

I hope this helps! Have a lovely day!! :)

A) 2x-5y=10
r-ruslan [8.4K]

Answer:

Step-by-step explanation:So to find it you need to eliminate either x or y. 2x-5y=10 over 4x-10y=20. In order to get y to eliminate you need one equation to have a positive 10y and a negetive 10y. So you multiply both sides of the first equation by negetive 2 so it is now, -4x+10y=-20. Notice how all the numbers in both equations are opposite this gives us ims infinitaly many sollutions. So it is not A. Or b it will do the same thing. The answer is either D or C hope this helps
