Hello,
y=k/x
if x=6 then y=42==>42=k/6==>k=252
if x=9 then y=252/9=28
Answer:
a=7, b=14
Step-by-step explanation:
a. 2/6=x/21
cross multiply=
2×21=x×6
then solve
42=6x
divide both sides by 6
x=42/6=<u>7</u>
b. 150/84=25/x
cross multiply=
84×25=150×x
then solve
2100=150x
divide both sides by 150
x=2100/150=<u>1</u><u>4</u>

we are given
the median price of homes decreased in the United States
old price is $360,000
after 1 year
new price is $253,800
Decrease in price = old price - new price
Decrease in price =$360,000 -$253,800
Decrease in price =$106200
now, we can find percent in decrease
percent in decrease = (decrease in price)/(old price) *100
percent in decrease is 29.5%.....................Answer
Answer:
46
