Answer:
Step-by-step explanation:
5*50 + 10y = 800
250+10y=800
10y=550
y=55
The soccer team collected $800 at a car wash fundraiser. They charged $5.00 for small vehicles and $10.00 for larger vehicles. The amount collected can be modeled by the equation 5x + 10y = 800, where x represents the number of small vehicles and y represents the number of larger vehicles. If the number of larger vehicles washed was 50, how many small vehicles were washed in total? 60. The soccer team collected $800 at a car wash fundraiser.

~~~~~~~~~~~~~~~~~~~~~~
5x + 10y = 800 and y = 50 ====>
5x + 10*50 = 800 ====> 5x + 500 = 800 ====> 5x = 800-500 = 300 ====> x = 300%2F5 = 60
Answer:
Step-by-step explanation:
<u>We know that:</u>
<u>Solution:</u>
- 30 kilometers = 1 hour
- => 30 x 21/2 kilometers = 21/2 hours
- => 15 x 21 kilometers = 21/2 hours
- => 315 kilometers = 21/2 hours
Hence, in 21/2 hours, the cyclist rides 315 kilometers.
