Answer:
20
Step-by-step explanation:
"Nine out of ten students prefer math class over lunch. How many students would not prefer math class if 200 students were asked about their preferences, if they followed the same percentage?"
Nine out of ten
Change total (ten) to 200
Ratio: 9/10 = x/200
180/200 = x/200
x = 180 prefer math
200 - 180 = 20 do not prefer math
Given:
Francis earns a weekly salary of $475 plus a 5.5% commission on sales at a girt shop.
To find:
How much would he earn in a week if he sold $700 in goods?
Solution:
We have,
Fixed weekly salary = $475
Commission percentage = 5.5% on sales.
Total sales of goods = $700
Total commission = 5.5% of 700
Now,
Total weekly salary = Fixed weekly salary + Commission
Therefore, the total weekly salary is $513.5.

That line that is made out of angles 1 and 2 is straight. What we know about straight lines is that they're 180°. This means that ∠1 and ∠2 are supplementary, adding up to 180°.
∠1 + ∠2 = 180
∠1 = (x + 81)
∠2 = (2x)
(x + 81) + 2x = 180
3x + 81 = 180
3x = 99
x = 33
The answer is x = 33.
