A high school choir had a car wash to raise money. The number of trucks washed was 5 fewer than twice the number of cars washed. If they washed a total of 34 trucks and
cars, how many trucks did they wash?
Please help

They washed 13 trucks.

Step-by-step explanation:

This question is solved using a system of equations.

I am going to say that

x is the number of trucks washed

y is the number of cars washed.

The number of trucks washed was 5 fewer than twice the number of cars washed.

This means that

They washed a total of 34 trucks and cars

This means that

How many trucks did they wash?

This is y.

Since

They washed 13 trucks.

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !

answer:

step-by-step explanation:

here, the total dishes = 10

dishes having meat = 3 ( chicken, meatloaf and hamburger )

thus, the probability of having meat on the chosen dishes = number of dishes having meat / total dishes

=

therefore, the probability of not having meat = 1- the probability of having meat on the chosen dishes

=

=

=

⇒ option b is correct.
