Answer:
38 or 38.33 cups of water.
Step-by-step explanation:
You need 5 cups of water for every 3 ounces of medication. We can set up a proportion: #oz of medication/#cups of water= #oz of medication/# cups of water. We can plug in some numbers from the problem.
3/5=23/n. You can use any variable, but I'm using n for how many cups of water Jim will need for 23 ounces of medication.
We can cross multiply: 3*n=5*23.
3n=115
We divide both sides by 3.
n=38.3333333.......
Rounding to the nearest whole number, Jim will need 38 cups of water, or 38.33 cups if you're rounding to the nearest hundredth.
Hope this helps :)

Step-by-step explanation:
I converted the numbers to decimals: 3.4 and 7.5. 3.4+a=7.5. 7.5-3.4= 4.1
X^2 + y^2 = r^2
15^2 + (-8)^2 = [sqrt(17)]^2
r= 17
cos(theta) = x/r = 15/17
