To compare the values,you must first calculate each given situation. The area of any given rectangle is length times width.
a) if w=6 and l=8
A= l*w = 8*6 = 48
b) if w=7 and l=7
A= l*w = 7*7 = 49
Therefore, the second case would yield a larger area. The answer would be w=7 and l=7. Total area would be 49 square units.
You said there were 40 yellow carsso 40×9 is 360
S+d=209
d=209-s
6.5s+2d=836.5
6.5s+2(209-s)=836.5
6.5s+418-2s=836.5
4.5s+418=836.5
4.5s=418.5
s=93
There were 93 salads sold that day.
Car normally has 4 wheeles
motorcycles normall have 2 wheels
c=cars
m=motorcycles
4c+2m=98
c+m=30
multiply second equation by -2 and add to the original equaiton
-2c-2m=-60
4c+2m=98 +
2c+0m=38
2c=38
divide 2
c=19
sub
c+m=30
19+m=30
m=11
11 motorcycles
19 cars
