Answer:

There are 13 motorcycles and 22 cars

Step-by-step explanation:

Let x represent the number of motorcycles, and let y represent the number of cars.  We can set up a system of equations to solve this...

x + y = 35          (there are a total of 35 vehicles)

2x + 4y = 114      (the total number of tires)

Solve the first equation for either variable...

y = 35 - x

Now substitute that value into the other equation and solve...

2x + 4(35 - x) = 114              (y becomes 35 - x)

Now solve...

2x + 140 - 4x = 114

     -2x = -26

            x = 13               (there are 13 motorcycles)

Now plug that value into either original equation to solve for y...

13 + y = 35

   y = 22    (there are 22 cars(

A set of equations is given below
Alex_Xolod [135]

Answer:

No solution

Step-by-step explanation:

This is no solution due to the fact that the slope of both of the equation are the same. So they are parallel. If the b value is the same then it is infinitely many solutions. Due to the fact that the b value is not the same they are a set of parallel line. Parallel line do not touch or intersect ever so there for this is a no solution set.

A school group wants to rent part of a bowling alley to have a party. The bowling alley costs $500 to rent, plus an additional c
Firlakuza [10]

Answer:

If there are N students, the total cost will be:

C(N) = $500 + $5*N.

And we want the amount that each student pays to be equal or less than $15.

then:

C(N)/N ≤ $15.

Then the inequality that represents this situation is:

($500 + $5*N)/N ≤ $15.

Now, let's solve this:

($500 + $5*N) ≤ $15*N

$500 ≤ $15*N - $5*N

$500 ≤ $10*N

$500/$10 ≤ N

50 ≤ N

So the minimum number of students needed is 50.

A square painting painting is surrounded by a frame. the outside edges of the frame are 3 inches in length, and the frame is 3 i
sdas [7]

Answer:

Area = 36 inches ^ 2

Step-by-step explanation:

There must be an error with the statement, because it is strange that the length of the frame is equal to its thickness.

Assuming that the data supplied is correct, we can do the following procedure.

Let's call L the length of the frame.

We know how much each side of the square measures.

L = 3 inches

We also know that the thickness (s) is:

s = 3 inches.

Then the area of ​​the frame is equal to:

Area = Perimeter * thickness

Area = 4L*s

Area = 3*4*3

Area = 36 inches ^ 2
