- 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:
19 nickel = .95
5 dimes = .50
Step-by-step explanation:
.95 + .50 = 1.45
Answer:
y=x+a/-2b

Step-by-step explanation:
x
Answer:
5/6
Step-by-step explanation:
Suppose x = 0.83 (3 repeating).
Multiply both sides by 10:
10x = 8.3 (repeating 3)
Now, multiply both sides by 10 again:
100x = 83.3 (repeating 3)
So, we have:
100x = 83.3 (repeating 3)
10x = 8.3 (repeating 3)
We see that if we subtract these two equations, the repeating 3s cancel out, and we're left with:
100x - 10x = 83 - 8
90x = 75
x = 75/90 = 5/6
Thus, the answer is 5/6.
Hope this helps!
