Sladkaya [172]

No, because then she would have to pay 21 dollars as a total and she only has 20.

Add adult plus Child,

5.75 + 11.25 = 17

add that to the book's price,

17+3.99= 2.99

it will exceed the budget by 99 cents.

The rectangles shown are similar. What is the value of x?

drek231 [11]

Since the rectangles are similar. The ratio of their sides will be the same.

So, we can write:

$x:18 = 4:6 \\ \\ 
 \frac{x}{18}= \frac{4}{6} \\ \\ 
x = \frac{4}{6} * 18 = 12$

Therefore, the left side of the bigger rectangle will be 12 units in length.
