Marla bought 12 books at a garage sale. Some of them were hardback and the rest were paperback. She paid $0.50 for each paperbac

olga nikolaevna [1]

Answer: The number of books bought were 9 paperbacks and 3 hardbacks

Step-by-step explanation: We shall start by assigning letters to the unknown variables, hence let the hardback be called h, while the paperback shall be called p.

If Marla bought 12 books at the garage sale, that means she bought

h + p = 12 ------(1)

Then she paid 0.5 dollars for paperback and 0.75 dollars for hardback and the total spent was 6.75 dollars for all of them, then we can express these as follows;

0.5p + 0.75h = 6.75 ------(2)

We now have a pair of simultaneous equations which are

h + p = 12 ------(1)

0.5p + 0.75h = 6.75 ------(2)

From equation (1), make h the subject of the equation,

h = 12- p

Substitute for h into equation (2)

0.5p + 0.75(12 - p) = 6.75

0.5p + 9 - 0.75p = 6.75

0.5p - 0.75p = 6.75 - 9

-0.25p = -2.25

Divide both sides of the equation by -0.25

p = 9

Now, substitute for p into equation (1)

h + p = 12

h + 9 = 12

Subtract 9 from both sides of the equation

h = 3

Therefore Marla bought 9 paperbacks and 3 hardbacks

Solve the equation.

Dafna1 [17]

Hi there!

Here are all the steps into solving this equation :

$\frac{9z+4}{5}$ - 8 = 5.4

Add 8 on each side of the equation → 5.4 + 8 = 13.4

$\frac{9z+4}{5}$ = 13.4

Multiply each side of the equation by 5 → 13.4 × 5 = 67

9z + 4 = 67

Subtract 4 from each side of the equation → 67 - 4 = 63

9z = 63

Divide each side of the equation by 9 → 63 ÷ 9 = 7

z = 7

There you go! I really hope this helped, if there's anything just let me know! :)
