Graham drove 42 1/3 miles in 1 1/3 hours. A. How many miles did he drive in one hour?
Nonamiya [84]

change to  improper fractions

42 1/3

(3* 42 +1) /3 = 127/3

1 1/3 = (3*1 +1) /3 = 4/3

127/3 divided by 4/3

copy dot flip

127/3 * 3/4

127/4

31 3/4 miles per hour

He drove 31  3/4 miles in one hour

31 3/4 miles  1 mile

------------     = ------------

1 hours             x hour

using cross products

31 3/4 * x =1*1

x = 1/  127/4 (copy dot flip)

x = 1 * 4/127

x = 4/127

it takes 4/127 of 1 hour (approx .03 hours)

Rainbow [258]

Answer: (5, 12)

-3x-3=2x+2

-x-3=2

-x=5

x=5

Plug x=5 to any equation

y=2(5)+2

y=12
