Students in a dance class filled out a survey. There were 25 girls and some boys whoparticipated in the survey. The results showed that 20% of the students prefer tap dance to
ballroom dance. There are 9 students who prefer tap dance. Which equation can be used to
find the number of boys ( x) who participated in the survey?
A. 0.2 x + 25 = 9
B. 0.2( x + 25) = 9
C. 0.2(25 – 9) = x
D. 25 + x = 0.2 × 9

Answers

Answer 1

Answer: Given:
Girls = 25
Boys = ?
Number of students who prefer tap dance = 9
percentage of students who prefer tap dance = 20%

We need to divide 9 by 20% to get the total number of students who filled out a survey.

9 ÷ 20% = 45 total number of students

Girls + Boys = 45
25 + Boys = 45
boys = 45 - 25
boys = 20

The correct equation is: B. 0.2(x + 25) = 9

0.2x + 5 = 9
0.2x = 9 - 5
0.2x = 4
x = 4 / 0.2
x = 20

Answer 2

Answer: B . Because it explains their was 25 girls and some boys so you add x to the 25
(X+25)0.2= 9

1. You would add 5 to -14, getting -9, which leaves you with 3x=-9. You would then divide -9 by 3, leaving you with x=-3.
2. First, subtract 22 from 10, getting -12=-2c. Next divide -12 by -2, leaving you with 6=c.
3. Add 17 to 18 to get 35=-5b. Then divide 35 by -5, leaving you with -7=b.
4. Subtract 12 from -12, giving you -24=-8x. Then divide 24 by 8, giving you 3=x.
5. Add .03 to -9, giving you 1.3n= -8.97. Divide-8.97 by 1.3 to get n=-6.9.
6. Subtract 7/9 from 2/9 leaving you with -5/9=-5/11h. Divide and get h=1 and 2/9.
