On a test matilda answered 12 out of the first 15 correctly. if this rate continues how many of the next 25 problems will she answer correctly?

The correct answer is 20.

Step-by-step explanation:

First let's set the facts:

A) Total answers: 15    C) Correct answers: 12

B) Problems to solve: 25   D)  Next correct answers: x

Now we have three known values and an unknown one, and what we are going to do is a cross multiplication.

A/B = C/D

We multiply the numerator of each side by the denominator of the other side, crossing the terms over.

AxD = BxC

15 x X = 25x12

15X = 300

X= 300/15

X=20

step-by-step explanation:

. your answer will contain x - and y -terms. (1 point) x ( ¿¿ 2 − 7 ) 2 +( y 2 − 9 ) 2 √ ¿ 12. what is the distance from the directrix (the crocodile river) to the point ( x , y )? write this equation. your answer will contain a y -term.
