First you need to find a common denominator, I'll use 72 so then it becomes:
52 32/72 + 8 63/72
Then I make them improper fractions so it becomes:
3776/72+639/72
Add them together and you have:
4415/72, this can be made into a mixed number:
61 23/72

Hope this helps :)

Ainat [17]

Answer:

Cost of each individual book = $10.5

Step-by-step explanation:

Given:

Cost of 3 book set = $24.81

Amount save = $6.69

Find:

Cost of each individual book

Computation:

Assume:

Cost of each individual book = a

Total cost = 3a

So,

Total cost = $24.81 + $6.69

Total cost = $31.5

So,

3a = $31.5

a = $10.5

Cost of each individual book = $10.5

How do I solve radicals??
Sav [38]
Your question is too general.  You might ask instead, "how do I simplify the radical sqrt(48)?"

sqrt(48) can b e simplified by rewriting 48 as the product of the perfect square 16 and the not-a-perfect-square 3:

sqrt(48) = sqrt(16)*sqrt(3) = 4*sqrt(3)    (answer)

In #76, rearrange the terms so that you have 3sqrt(7x+4)=15.  Then divide both sides by 3, obtaining sqrt(7x+4) =5.  Squaring both sides:  7x+4=25.
Solve this linear equation for x.
