(CL) Perform the operation and simplify the resulting fraction:
c
3/4 c− 7/12 + 7/24 c+ 2/3 − 1 /6 c

Answers

Answer:

Step-by-step explanation:

This is just a algebra problem. That means that we need to combine like terms. Variable on one side, number on the other side.

[tex]\frac{3}{4} c-\frac{7}{12} +\frac{7}{24}c+\frac{2}{3} -\frac{1}{6} c[/tex]

Reformat :)

Then we want to make it so that all the fractions have the same denominator.

[tex]\frac{18}{24} c-\frac{14}{24} +\frac{7}{24} c+\frac{16}{24} -\frac{4}{24} c[/tex]

Then combine like terms and solve.

Hope this helps!

Enola spent $48 at a used book store where hardback books sell for $12 each and paperback books sell for $8 each.

A. Write an equation in standard form where x represents the number of hardback books and y represents the number of paperback books she bought that day:




B. If she bought 2 hardback books how many paperback books did she buy?

Answers

Answer:

A. 48= 12x + 8y

B.  3 paper back books

Step-by-step explanation:

A. If x represents hardback book, and they are $12 each then that is 12x. y = the paperback books that are $8 each, so 8y. and 48 is the amount that Enola spent.

B. 2 hardback books would equal $24.  If you had 3 paperback books that would equal $24. And the two together to get the total amount of $48.

Yes.
