To find equivalent numbers you multiply the top and bottom by the same number. Examples are: 2/10 (by 2), 3/15 (by 3), 4/20 (by 4), etc.
1 * 9 = 9
------------
5 * 9 = 45
So another is 9/45
hope it helps!
I'm guessing it is C because after you solve for n (you need to multiply the five over to isolate n), you get 20.
I entered the equation into a graphing calculator. clicked table and then scrolled down to the profit of $3,563. 55 skateboards
you could also try this equation. B=the number attached to x so 10, a=the number attached to x^2(or in other equation x^3 etc) so 1 and c is the number, so -12.
The rate of Car A is x
The rate of Car B is x - 5
They travel the same distance. So we can make an equation:
4(x) = 4.5(x-5)
Solve for x.
4(x) = 4.5(x-5)
4x = 4.5x - 22.5
Subtract 4.5x on both sides
-0.5x = -22.5
Divide by -0.5 on both sides
x = 45
But we want the speed of Car B which is x - 5
So Car B's speed is 45 - 5 = 40
Your answer is 40
Answer: The slope is 3
Step-by-step explanation:
For each unit of run in the x-values, there is an increase of 3 in the y-values. Slope is Rise over Run so 3/1 = 3
