For answer b the answer is 3d + 5w
For answer c the answer is 2a + 3b + 4c
It would be C . You can figure it out by seeing how many times -4 goes into -28, which is 7 times. If you're not sure whether it is negative or positive then you could either use a calculator to check or remember this rule a negative times a negative is a positive which means your answer would have been 28 not -28.
Answer:
27
Step-by-step explanation:
2h+11=65
2h= 65-11
2h=54
then divide both side by two to find h
You could use 10, 6 and 7.
Using ten would have them all equal 50, using 6 would have them all equal 30 and using 7 would have them all equal 35.
Hope this helps!
