Answer:
width=4
length=18
Step-by-step explanation:
length-6=3width
length=3width+6
also:
perimeter of the rectangle=2(length+width)
44/2=width+length
22=width+length
now put the length we found in the 1st equation, in 22=width+length
=>22=width+3width+6
22-6=4width
width=4
now do the exact same thing with one of these equations:
22=width+length
length=3width+6
I'd do it with the 1st one:
22=4+length
22-4= length
length=18
Answer:
1/7
Step-by-step explanation:
because for the simple reason look at the question
The total distance is given as 18 miles
she traveled at 45 miles per hour for 20 minutes
20 minutes = 20 / 60 = 1/3 of an hour
45 miles per hour x 1/3 of an hour = 15 miles driven
18 total miles - 15 miles driven = 3 miles left
she then drove at 20 miles per hour
20 miles per hour / 60 minutes per hour = 1/3 mile per minute = 1 mile every 3 minutes
3 miles x 3 minutes = 9 minutes to drive the final 3 miles
20 minutes + 9 minutes = 29 total minutes to drive to work
she left at 7:15
7:15 + 20 minutes = 7:35 am she arrived at work
I think I did the second one for you earlier.
First one:
216*(2/3) = (\sqrt[3]{216})^2 = 6^2 = 36
