The best way to solve this is to put it into a proportion:
So you cross multiply to get:
(the 21 is from
•84)
Then multiply by
And you get $28, so the reduced price would be $28.
Answer:
volume = x(x+2)(2x+1) = 2x^3+5x^2+2x
a = 2
b = 3
c = 5
d = 2
e = 2
f = 1
That is the Identity Property of Multiplication
Divide the first one by the second and the answer will be B.
We have to add 8/15 to 2/5.
To add two fractions we have to make them have the same denominator, so we have to convert 2/5 to have a denominator of 15. To do this, we have to multiply 2/5 by 3 and then we can add the fractions:
Answer: 14/15
