The number of books the library holds before it received the grant is 17,312 books

Let the original number of books in the library be x

If the State Library received a three-year grant to add 69,678 books to their collection, the total number of books will be x + 69,678

If during a used book sale, the library sold 430 books, the remaining books will be (x+69,678) - 430 = x + 69,248

If the collection now is five times more than the original number of books, then;

x + 69,248 = 5x

5x - x = 69,248

4x = 69,248

x = 69,248 /4

x = 17,312

Hence the number of books the library holds before it received the grant is 17,312 books

Casi drove 135 miles in 3 hours. Use a proportion to find how long it would take her to drive 360 miles at the same speed.

galina1969 [7]

Answer:

8 hours

Step-by-step explanation:

We are given that

Casi traveled distance in 3 hours=135 miles

We have to find the time taken by Casi to drive 360 miles at the same speed using proportion .

Let time taken by Casi to drive 360 miles=x

We know that

Speed= $\frac{Distance}{time}$

Using proportion

$\frac{a}{b}=\frac{c}{d}$

$\frac{135}{3}=\frac{36}{x}$

$x=\frac{360\times 3}{135}$

$x=8$

Hence, the time taken by Casi to drive 360 miles=8 hours

If you take the 30% and divide from the 50% you get .6 multiply that by a 100 you get 60.

30/50=.60
.60x100=60
