If brian is 8 and his brother is twice his age, his brother is 16. His brother is 8 years older so when Brian is 11 he will be 19
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
The answer to 3/4x2/5 is 3/10
66 2/3% of 22= 14.6666667 is the answer.
