15 ÷ 5 = 3
20 ÷ 5 = 4
15/20 = 3/4
- Bicycles: 1 seat and 2 wheels
- Tricycles: 1 seat and 3 wheels
So with this, we will be making a system of equations. One representing the amount of seats and one representing the amount of wheels. Let x = bicycles and y = tricycles:

With this, I will be using the substitution method. Firstly, subtract y on both sides of the first equation:

Next, substitute x in the second equation for (32 - y) and solve for y:

<u>In short, there are 13 tricycles.</u>
Answer:
x = 2, HJ = JK = 11
Step-by-step explanation:
Given that H is the midpoint of JK , then
HJ = JK = 6x - 1 and
HJ + JK = JK , that is
6x - 1 + 6x - 1 = 3x + 16 ← simplify left side
12x - 2 = 3x + 16 ( subtract 3x from both sides )
9x - 2 = 16 ( add 2 to both sides )
9x = 18 ( divide both sides by 9 )
x = 2
Then
HJ = JK = 6x - 1 = 6(2) - 1 = 12 - 1 = 11
