Answer:
is the fraction of 8th graders who are boys.
Step-by-step explanation:
Let total number of 8th graders = 
Given that,
of 8th graders play sports
8th graders who play sports = 
Also, Given that,
of 8th graders that play sports are boys
Number of 8th graders that play sports, and are boys = 
Hence, the answer is:
is the fraction of 8th graders who are boys.
7 miles per hour you can find this answer by doing 28 divided by 4.
Taking 2x is power of 3.
So it will be like 3^(2*1/2) + 1
You are replacing 'x' with 1/2
and the equation becomes 3^1+1
So, f(1/2) = 4
Answer is 4.
If its like
<span>3^(2x+1)
Then its like 3^[(2*1/2) +1]
It becomes 3^(1+1) = 3^2 = 9
So, the answer is 9

<h3>Given :-</h3>
- Pranav ran 20.3 km more than Branda

To find :
- No. of kilometers did Brenda run.

<h3>Let :</h3>
- No. of kilometers ran by Brenda be x.

<h3>Solution:</h3>

Equation formed:-

Total distance covered by Pravan = More distance covered by Pravan + distance covered by Brenda.
Therefore:-


Write the equation


When we transfer 20.3 to left side the positive sign (+) will change into negative sign (–)


Arrange the equation because x is always represented at left side.


After subtracting 38.6 with 20.3 we will get result as 18.3 .


It is 45 because angle EBC is congruent to CDE (x) because of a rule called alternate angles. so x= 45°
