Answer:
The answer for this problem is 14.825
Step-by-step explanation:
There are about three steps for this problem
The first is finding out what is 45% of 3.5 yds. You do this by multiplying 3.5 and .45 and you get 1.575
The second step is finding the second carpets length. All you have to do is add the number we got from multiplication which is 1.575 to 3.5 and you get 5.075. The reason we added those numbers is because the problem says the second carpet is 45% "longer" than the first carpet.
The third and final step is to add up all three values and you get 14.825!
Answer:
-2 1/2
Step-by-step explanation:
The first thing to do here is turn 8 3/4 and -3 1/2 into fractions(we will convert to mixed number at the end). So you get: 35/4 and -7/2.
That gives you (35/4)/(-7/2).
Then you use keep change flip to simplify this.
(35/4) * -2/7 = 2.5
2.5 as a mixed number is:
-2 1/2
