Answer:
The ratio between two values A and B is just the quotient between these two values:
ratio = A/B
a) $280 in 7m
Here the ratio is:
$280/7m = $40/m
This also can be read as:
$40 per meter.
b) 105 miles in 2 hours
Here the ratio is:
105mi/2h = 52.5 mi/h
This also can be read as:
52.5 miles per hour
c) $33 for 5lb
The ratio is:
$33/5lb = $6.6/lb
This can be read as:
$6.6 per pound.
d) 50 pages in 2 hours
the ratio is:
(50 pages)/2h = 25 pages/h
this can be read as:
25 pages per hour.
P=98 m
l +9=4w
p=2l+2w
98=2(4w-9) +2w
98 = 8w-18+2w
116=10w
w=11,6 m
l = 4w-9 = 4*11,6 -9 = 46,4 -9 = 37,4 m
w=11,6 m
l= 37,4 m
The answer in 27 $$$$$$$$$$$$$$$$$$$$$$$$
