20/30 or you can put it down as 6 2/3 or 6.6
We want to multiply
by
, and simplify.
The first thing we do in this type of problems, is factorize as much as possible, and see what cancels out.
can be factored into (r+2)(r+5) as 2 and 5 are two numbers whose sum is 7, and product is 10.
Similarly
can be factoredinto (r-10)(r+5) as -10 and 5 are two numbers whose sum is -5, and product is -50.
Last, (3r-30) can be factored as 3(r-10).
Thus the product is equal to:
,
so canceling all equal terms in the numerator and denominator we are left with
r+2.
Answer: A) r+2
Step-by-step explanation:
The answer needs to be in ounces so convert the pints and cups to ounces to solve. There are 16 ounces in a pint and 8 ounces in a cup. 2 pints would be 2 X 16 ounces and 3 cups would be 3 X 8 ounces.
