Answer:
84mm^3
Step-by-step explanation:
multiply 12 by 7
Answer:
It might be -10:9 or 9: -10 Hope this helps :)
The ratio given says this - 3 puppies : 2 adults = 5 total dogs
You are given (?) puppies : (?) adults = 80 total dogs
In this case, you are trying to find the number of puppies, so you do not need to care about the number of adults. You need to compare the ratio with the actual amount.
Total/puppies = total/puppies
5/3 = 80/(?)
Now, cross multiply.
5(?) = 240
Divide both sides by 5 and you get your answer.
(?) = 48
The answer is D. Solve for the first variable in one of the equations, then substitute the result into the other equation.
