Answer:
20 ounces of cleaner
Step-by-step explanation:
Water 48 oz is 60% of unknown total. 60% = 3/5. Create equation and solve
48= 3x/5. 240= 3x. 80 = x
Total of water, bleach and cleaner is 80 ounces
60% + 15% = 75%
100% - 75%= 25% cleaner
.25 × 80 = 20 ounces
You are told the ages of Karen and David in terms of Michelle's age.
Let m = Michelle's age.
Michelle's age = m
Karen's age = m + 6
Michelle is two years younger than David, so David is two years older than Michelle.
David's age = m + 2
Add the ages and get 62.
m + m + 6 + m + 2 = 62
3m + 8 = 62
3m = 54
m = 18
Michelle is 18 years old
Karen is 6 years older, so she is 24 years old.
David is 2 years older than Michelle, so he is 20 years old.
So...the diameter is increasing at a rate if 2cm/minute, therefore the radius (1/2 the diameter) is increasing at half the rate. You will learn how to calculate the rate of change at a specific point in time in calculus.

Answer:
the answer is 50
Step-by-step explanation:
first you plug in the x and y in the equation, making it 6(7)=-4(-2) then, you multiply the numbers together, making the equation 42+8. finally, you add those numbers together, giving you the answer 50
