<u>Direct Variation:</u> 

when y = 7: 
14 = 15x

<u>Inverse variation:</u> y*x = k
15 * 2 = k
30 = k
when y = 7: 7 * x = 30

Answer:
100,000,0
Step-by-step explanation
To solve this problem you need to start with 100, since 100 has 2 zero's you want to add 2 zero's 2 times in a row, like this-- 100+00=10,000+00=100,000,0.
Thus your answer: 100,000,0

(120 miles)/(7/4 hours) = 480/7 miles/hour = 68 4/7 miles/hour
Answer:
4.4%
Step-by-step explanation:
solution:
principal (p) = $300
time(t) = 3 years
interest (I ) =$40
rate (r) = ?
we know that,
I = (PTR)/100*
OR, 40 = (300 *3 * R)/100
or, 40 = (900R)/100
or, 40 = 9R
or, 40/9 = R
or, R = 4.4%
Rate(r) =4.4%
