Answer:
Step-by-step explanation:
=>
Cross Multiplying
=> x * 3 = 5 * 17
=> 3x = 85
Dividing both sides by 3
=> x = 85/3
=> x = 28.3 (To nearest tenth)
Answer:
Step-by-step explanation:
The proportion is given,
We need the x variable isolated on one side, so we can find the value of x that makes the proportion true.
Multiply both sides of the equation by 5.
Simplify the equation.
The value of x that makes the proportion true is 28.3 (rounded to nearest tenth place).
Answer: He should use 14 fluid ounces of soap.
Step-by-step explanation:
1. You need to make the conversion from cups to ounces.
You know that:
Then:
2. According to the information given in the exercise, Kevin must use 4 fluid ounces of concentrated soap for every 3 cups of water or 24 fluid ounces of water.
Then, knowing that he uses 84 fluid ounces of water to make an all-purpose cleaner, you can set up the following proportion:
Where "x" is the total fluid ounces of soap that Kevin should use.
3. Solving for "x", you get this result:
