"15 cookies to 40 brownies"
An hourglass is turned over with the top part filled with
sand. after 3 minutes, there are 855 ml of sand in the top half. after 10
minutes, there are 750 ml of sand in the top half. This can be represents a two
points ( 3, 855) and (10, 750) . using this to solve the slope m =
(750-855)/(10-3) = -15. And using one point the equation is y = -15x + 900.
Answer:
In order to find x, you will have to use the operation of equality to isolate the x.

<em>Now, use the division property of equality and divide by 15 on both sides. This will cancel out the 15 on the left side of the equation and isolate the x completely.</em>

<em>Thus, this is your answer:</em>

Answer:
ye
Step-by-step explanation:
First, let's write down this inequality:
<span>There are at least 245 students enrolled in the school.
y≥245
This inequality says what the sentence says!
now, the number of teachers must be:
x≥2*(y/25)
(two times the number of groups of students of 25!)
so those two inequalities, taken together will be the answer!
