One pound of grapes costs $1.55. Which equation correctly shows a pair of equivalent ratios that can be used to find the cost of 3.5 pounds of grapes? StartFraction 1.55 over 1 EndFraction = StartFraction x over 3.5 EndFraction StartFraction 1.55 over 1 EndFraction = StartFraction 3.5 over x EndFraction StartFraction 1 over 1.55 EndFraction = StartFraction x over 3.5 EndFraction StartFraction x over 1.55 EndFraction = StartFraction 1 over 3.5 EndFraction

the answer is d

a) 0,0; 1,1; and 2,2

step-by-step explanation:

these have the exact same coordinates, thus they are the correct function.

cross multiplying, we get :

⇒ (3) × (5) = (9) × (x)

⇒ 15 = 9x

45.36 feet per second

step-by-step explanation:

tyrone travels 30 miles in 58.2 minutes.  

1 mile = 5280 feet; this means he travels

30(5280) = 158400 feet in 58.2 minutes.

1 minute = 60 seconds; this means he travels 158400 feet in

58.2(60) = 3492 seconds.

this gives us the unit rate of

158400/3492 = 45.36 feet per second.
