Let x inch be the width
x×2+(x+7)×2=34
2x+2x+14=34
4x=20
x=5
the length=5+7 i.e.12 inches
the width=5 inches
Area=5×12=60 inches
P=2 (l+w)
we know P=284
we also know that l= w+50
so replace l in the equation with w+50
284=2 (w+50+w)
284=2 (2w+50)
divide both sides by 2
142=2w+50
subtract 50 on both sides
98=2w
divide both sides by 2
49=w
so width is 49, and we need to add 50 to it to find the length
l= 49 +50
l=99
K - Kitchen
b - Bedroom
l - Library
k = 4b
l = 14b
k + b + l = 817 pounds
4b + b +14b = 817 pounds
19b = 817 lbs
b = 817/19 pounds
b = 43 pounds
Since k = 4b
k = 4 * 43 pounds
k = 172 pounds
Answer:
Mean = 30.3
Median = 30
They scored 30 or more points on 11 games.
Step-by-step explanation:
Mean = all the numbers added together divided by 21
636/21 = 30.3
Median is the middle number (the 11th) = 30
After 20% reduction the price is $48 which means $48 is only 80% of the original price...so let x= original price
<span>48=.8x </span>
<span>60=x </span>
<span>it was $60
</span>
