6+3n≤40
Use inverse operations i.e.
4x+2<10
-2 -2
4x<8
4*x/4<8/4
x<2
It's m. All you have to do is distribute
3/4 Of X(Capacity) = 18 Gallons
X = 18*4/3
= 6*4
= 24 Gallons
Capacity of Tank = 24Gallons
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 :)
