Answer:
6 ounces of water
Step-by-step explanation:
In this question, we are asked to calculate the amount in ounce that would be added to the recipe.
From the question, we can see that the recipe requires 3/4 cups of water.
From the question also, we can also see that one cup equals 8 ounces.
Now to know the amount of water that is to be added, what we need to do is to simply multiply the fraction of water in the recipe by 8 ounces
This is equal to 3/4 * 8 = 6 ounces
Hence, she needs to add a total of 6 ounces of water to the recipe
Answer:
x = 39
Step-by-step explanation:
Answer:
x = -5 or x = -12
Step-by-step explanation:
x^2+17x+72=12
Subtract 12 from both sides.
x^2+17x+72-12 = 12-12
x^2+17x+60=0
Then factor the left side of the equation
(x+5)(x+12) = 0
Then set the factors equal to 0
(x+5)=0 or (x+12)=0
Therefore x=-5 or -12
