Answer:
x = 91.5
Step-by-step explanation:
for 30.5 miles travelled gas used is 1 gallon ← unit rate
To calculate distance travelled multiply gas used by 30.5
For 3 gallons used
distance travelled = 3 × 30.5 = 91.5 miles
⇒ x = 91.5
Answer:
132 bicycles
Step-by-step explanation:
The ratio of bicycles to cars is 15:60. Before anything, we need to simplify this ratio. 15/15 = 1, and 60/15 = 4. So, now we have 1:4. Since the question asks for 33 bicycles, we multiply the number of bicycles, 1, by 33. Since we are multiplying the bicycles, we also need to multiply the cars. 4 x 33 = 132.
33:132. We need 132 cars.
