Let x be a number of skateboards and y be the number of bicycles in Eddie's repair shop.
Eddie asks the girls to order 54 new wheels for 21 skateboards and bicycles, then
x+y=21.
One scateboard has 4 wheels, then x scateboards have 4x wheels, one bicycle has 2 wheels, then y bicycles have 2y wheels. In total there should be ordered 54 wheels, so
4x+2y=54.
Solve the system of equations:
From the first equation Substitute it into the second equation:
Then
Answer: 6 scateboards and 15 bicycles.
Answer:
Parallel
Step-by-step explanation:
The graph equation of g(x) could be represented as a function of f(x)
As we can observe
f(x) and g(x) have the same slope=
The difference is that g(x) is 6 units down of f(x) measured on y-axis
as slopes are equal
both graphs are parallel

Your answer would be (60x + 240)/(8x² + 32x).
When multiplying fractions, you are able to just multiply the numbers across like you do usually, which gives us the expression 5(12)(x + 4) as the numerator, and 4(x)(2x + 8) as the denominator. Then all we need to do is expand and simplify:
5 × 12 = 60
60(x + 4)
= 60x + 240
4 × x = 4x
4x(2x + 8)
= 8x² + 32x
So your final expression is (60x + 240)/(8x² + 32x).
I hope this helps!
