1 ft = 12 inches......1 yd = 36 inches
carol has 54 inches
Tino has 7.5 ft......7.5 * 12 = 90 inches
baxter has 3.5 yds......3.5 * 36 = 126 inches
for a total of : (54 + 90 + 126) = 270 inches total <===
1 ft = 12 inches....so 270 inches = 270/12 = 22.5 ft <==
1 yd = 36 inches..so 270 inches = 270/36 = 7.5 yds <==
Answer:
The mean is 28.3 or 28
I added it all and then divided it by how many different numbers there were.
A very simple example is:

What you need to is just distribute x into the parenthesis, so once x times the first term (a) and once x times the second term (b)
I hope you got
the idea
Answer:
2(4b-1)
Step-by-step explanation:
1. You would have to distribute first. So basically you just multiply 4 · 2b which gives you 8b and then 4 · 2
Answer to first step: -10+8b+8
2. Add the numbers. It should be -10 + 8 which would give you -2
Answer to second step: -2 + 8b
3. Rearranging the terms. So, instead of doing -2 + 8b you would have to do 8b - 2
Answer to third step: 8b - 2
4. 2(4b - 1) Find what times what gives you 8 (not 1 times 8) and the same for -2
Hope this helped!
