there are 40 jump ropes in the gym class. there are 4 times more red jump ropes than blue ropes. how many of each color are there?
i can't seem to write the equation. help!!!!!!!!
x+ 4x=40
5x=40
x=8
To solve this problem, let's break it down step by step.
First, let's assign variables to represent the number of blue and red jump ropes. Let's say "x" represents the number of blue jump ropes.
According to the problem, there are 4 times more red jump ropes than blue jump ropes. So, the number of red jump ropes would be 4 times the number of blue jump ropes, which can be represented by 4x.
Now, we can set up an equation to represent the total number of jump ropes in the gym class. The total number of jump ropes is given as 40.
So, our equation becomes: x + 4x = 40.
Combining like terms on the left side of the equation, we get 5x = 40.
To solve for x, we divide both sides of the equation by 5. This gives us x = 40/5, which simplifies to x = 8.
Therefore, there are 8 blue jump ropes and 4 times that amount, or 32, red jump ropes in the gym class.
