Let's let "5x" represent the number of boys in the school play and "7x" represent the number of girls in the school play. 5x = boys 7x = girls If we know that the total number of students in the play equals 48, then that must be that both the number of boys and girls combined must equal 48: 5x + 7x = 48 12x = 48 x = 4 Now, take your x-value and plug it into both the boys' and girls' values to figure out how many boys and girls there are in the play: 5x = 5 (4) = 20 boys
7x = 7 (4) = 28 girls To find out how many more girls there are than boys in the play, just subtract the number of girls minus the number of boys: # girls - # boys = 28 - 20 = 8 This means that there are 8 more girls than boys in the school play
Answer:
The interpretation of that same problem is listed throughout the section below on explanation.
Step-by-step explanation:
Interpretation:
Researchers seem to be confident with 95% that the sample selection standard error seems to be + as well as - 4 percent respectively.
This same margin of sampling error would then decrease from either the mean or average value by four percentage points smaller or even larger, it describes the survey method.

Step-by-step explanation:
Earnings for mowing 2 lawns on Peach St
= 2 x $15.32
= $30.64
Earnings for mowing 4 lawns on Onion St

= $51.92
Total earnings
= $30.64 + $51.92
= $82.56
Answer:
Step-by-step explain
3n - 2 = n + 10. add 2
3n = n + 12 subtract n from both sides
2n = 12. divide by 2
N = 6
