In last Saturdays parade Tom counted a total of 76 bicycles and tricycles, for a total of 227 wheels. How many tricycles were in the parade?

i got a
73 x 3 =219 wheels in tricycle
3 x 2 = 6 wheels in bicycle
for a total of only 225 wheels im short by 2 wheels

i go 75 tricyles x 3 = 225 wheels

1 bike x 2 = 2 2wheels
total of 227 wheels
75 tricyles 1 bicyles

bikes - x

trikes - 76-x

solve:
2x + 3(76-x) = 227
2x + 228 - 3x = 227
-x = -1
x = 1

so 1 bike and 75 trikes

check: 1(2) + 75(3) = 227

To find the number of tricycles in the parade, let's assume there were "x" tricycles and "y" bicycles.

We know that the total number of bicycles and tricycles in the parade is 76, so we can write the equation:

x + y = 76 (equation 1)

We also know that the total number of wheels is 227. Since each tricycle has 3 wheels and each bicycle has 2 wheels, we can write another equation:

3x + 2y = 227 (equation 2)

Now we have a system of equations. To solve for the number of tricycles, we can use the method of substitution or elimination.

Using the substitution method, we can solve equation 1 for y:

y = 76 - x

Substituting this value of y into equation 2, we get:

3x + 2(76 - x) = 227

Simplifying the equation gives:

3x + 152 - 2x = 227

Combining like terms:

x + 152 = 227

Subtracting 152 from both sides:

x = 75

Now that we know the value of x, we can substitute it back into equation 1 to find the value of y:

75 + y = 76

Subtracting 75 from both sides:

y = 1

Therefore, there was only 1 tricycle in the parade.
