Answer:

  72 +13n = 163

  7 nights

Step-by-step explanation:

At 13 pages per night, Mario will read 13n pages in n nights. That plus the pages already read will total 163:

  equation: 13n +72 = 163

__

To solve this, we can subtract 72, then divide by the coefficient of n.

  13n = 91 . . . . . . subtract 72 from both sides

  n = 7 . . . . . . . . divide both sides by n

Mario read 7 nights.

What is 27.35 expressed as a mixed number?
zheka24 [161]
Firstly, you know you have 27 (35/100)

Make this an improper fraction.   2735/100

Simplify this as much as you can.  547/20

Find how many times 20 will go into 540, and use the 7/20 as the fraction part of your mixed number.

Now, make as many whole as you can and states your remaining. 27 7/20

Solve the inequality.
marysya [2.9K]

Answer:

\huge x >  \frac{7}{3}  \\

Step-by-step explanation:

8( \frac{1}{2} x -  \frac{1}{4} ) > 12 - 2x \\

<u>Expand the terms in the bracket</u>

That's

8( \frac{1}{2} x) - 8( \frac{1}{4} ) > 12 - 2x \\ 4x - 2 > 12 - 2x

Move -2x to the other side of the inequality

4x + 2x - 2 > 12 \\ 6x - 2  > 12

<u>Move - 2 to the other side of the inequality</u>

6x > 12 + 2 \\ 6x > 14

Divide both sides by 6

\frac{6x}{6}  >  \frac{14}{6}  \\

We have the final answer as

x >  \frac{7}{3}  \\

Hope this helps you
