Answer:
20 miles
Step-by-step explanation:
If Maria has been riding for 2 1/2 hours and Aiden only for 2. That means that the first 4 miles she rode alone was for 1/2 hour. So that is the rate.
1/2 hour for every 4 miles
Maria rode for 2 1/2 hours divided by 1/2 hours is 5. So 5 x 4mi = 20 miles
Plugging into the Given Formula the value of y:

Multiply the left side:

Add 14 to both sides to get:

Divide both sides by 8 and we get:

Therefore, x=7 and the proof is complete
<span>If Hunter raises beetles in a square of compost with a size of 6 ft by 6 ft and having 500 beetles, and then you are to find the number of beetles with a side length that is four times longer, then you can solve this by ratio and proportion.
A = s</span>²
A = 6²
A = 36 ft²
if s = 4*the original length, then the new area is
A = 24²
A = 576 ft²
500 beetles/36 ft² = x number of beetles/576 ft²
x = 8,000 beetles
