Answer:
Step-by-step explanation:
Let
w------> the weight in pounds
we know that
A delivery company charges an extra fee for a package that weighs more than 100 pounds
so
For
-----> the company charges an extra fee
therefore
For
----> the company not charge an extra fee
So the three numbers can be turned into fractions.
1/5, 1/4, and 4/20.
fractions can be turned into decimals by dividing the denominator into the numerator.
now we have 0.2 , 0.25 , and 0.2
greatest to least, the numbers are 0.25 , 0.2 , and 0.2
(both 0.2s are equal, so order of those doesn't matter)
Answer:
No solution
Step-by-step explanation:
10x + 30 +16 x +24 = 26 x + 57
26x + 56 = 26x + 57
56 ≠ 57
Inverse variation means y=k/x (direct variation is y=kx) so we can use the info given to find the constant k
y=k/x
6=k/900
k=6(900)
k=5400 so the equation is:
y=5400/x or more accurately for this problem
t(v)=5400/v then:
t(800)=5400/800
t(800)=6.75 hours
