Answer:
161 seniors
Step-by-step explanation:
According to the problem, given data are as follows:
Total number of sophomores = 300
Sophomores to junior ratio = 5:4
So, Number of Juniors = 300 × (4 ÷ 5)
= 240
Now, Juniors to senior ratio = 3:2
So, we can calculate the number of seniors by using following method:
Number of seniors = 240 × ( 2 ÷ 3)
= 240 × 0.67
= 160.8 or 161
Answer:
y = 0.9x
Step-by-step explanation:
A movie theater sends out a coupon for 10% off the price of a ticket, so the price of the ticket with the coupon is 100% - 10% = 90% of the original price.
Let
x = original price
y = price of the ticket with the coupon
Then
x - 100%
y - 90%
Write a proportion:
Cross multiply:
Since the original price and final price are always greater than 0, then the graph of this equation is in the first quadrant (see attached diagram)

Answer:
A.
Step-by-step explanation:
Use the distributive property.
(2<em>x</em> − 2<em>y</em>)(2<em>y</em> + 8)
= 2<em>x</em>(2<em>y</em> + 8) − 2<em>y</em>(2<em>y</em> + 8)
= 4<em>xy</em> + 16<em>x</em> − 4<em>y</em>^2 − 16<em>y</em>
