Answer: 20 builders.

Step-by-step explanation: For 10 builders to build a house in 20 days, the ratio is 1:2. For builders to build a house in 10 days, the ratio is x:10. You then cross multiply 1:2 and x:10. Then x=20 so 20 builders.

City Cab charges a flat fee of $3 plus 0.50 per mile. Henry paid $10.50 for a cab ride across town. The equation 3 + 0.50m = 10.
Anton [14]

Answer:the number of miles that Henry traveled is 15

Step-by-step explanation:

Let m represent the number of miles travelled.

City Cab charges a flat fee of $3 plus 0.50 per mile. This means that the total amount that city Cab charges for m miles would be

3 + 0.5m

Henry paid $10.50 for a cab ride across town.

The equation representing Henry's cab ride would be

3 + 0.50m = 10.50

Subtracting 3 from both sides of the equation, it becomes

3 - 3 + 0.50m = 10.50 - 3

0.5m = 7.5

m = 7.5/0.5 = 15 miles
