Step-by-step explanation:
We first need to find what is 72% of 25
<u>Therefore:</u>
72% of 25
=> 18
<u>Now, since we have the number of kids who are interested in math, we must do backwards equation:</u>
<u></u>
25 - 18
=> 7
Answer:
We can use the Pythagorean Theorem to help determine if a triangle is a right triangle, if it is acute, or if it is obtuse. ... Conversely, if \begin{align*}a^2 + b^2 < c^2\end{align*}, then lengths \begin{align*}a, \ b\end{align*}, and \begin{align*}c\end{align*} make up the sides of an obtuse triangle.

Answer:
(7, -4.5)
Step-by-step explanation:
25−x=−4y ---> x=25+4y
3x−2y=30
use x to substitute into the second equation
3 (25+4y)-2y = 30
75+12y-2y=30
75+10y=30
10y=-45
y=-4.5
3x-2(-4.5)=30
3x+9=30
3x=21
x=7
check:
25-7=-4*-4.5
18=18 (yes)
3*7-2*-4.5=30
21+9=30
30=30 (yes)
the answer is D. twenty-five seconds over one-fourth mile = 100 miles per hour.
