Add them all together and there is your sum
Slope is 3/4

We can write a proportion for this problem
10,000drops of a liquid is 10 fluid ounces
100 drops of a liquid is x fluid ounces
x=100*10/10000 =1/10 = 0.1 fluid ounces
To simplify, you just need to multiply 9 by both 3t and 4b separately:
9(3t + 4b) = (9)(3t) + (9)(4b) = 27t + 36b
That what to simplify means. Hope this helps!
