Which speed is fastest? A.) 18ft in 20min
B.) 90ft in 2.5 hrs
C.) 20 yds in 1.5 hrs
D.) 3 2/3 yds in 15min

C

Step-by-step explanation:

the answer is "C" because 20 yards is equal to 20⋅3=60 feet.

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4

-362

step-by-step explanation:

(12)(4)+2(12)-34(12)+2(12)-3

  \/         \/         \/         \/

  48 +   24 -   408 + 24 - 3
