(1.5,0) ? I'm not sure...
The answer, I believe, is tuition like how people say this this and this is the amount of my college tuition
<span>2x-3y=12 -
4x+6y=5
You want to get rid of y first so multiply the first equation by 2:
4x - 6y = 24
-4x + 6y = 5
now add the 2 equations together:
but as you can see, you cant solve this and if you add the equations together you get 0 = 29
so in result the answer is No Solution</span>
Answer:
b = 24
explanation:
you use the Pythagorean theorem.
a^2 + b^2 =c^2
so we do 32^2 + x^2 = 40^2 then solve
32 squared is 1024 and 40 square is 1600 so you minus the 2 and get 576 then you square root 576 and you finally answer is 24
Answer: 20 liters
<u>Step-by-step explanation:</u>
The mixture is 60 liters. The ratio is 2 : 1 (2 parts to one part)
60 ÷ (2 + 1) = one part
60 ÷ 3 = 20
Therefore, the ratio of 2 : 1 means 2(20) liters milk to 1(20) liters water
If we change it to a ratio of 1 : 2, then we have 1(20) liters milk to 2(20) liters water.
2:1 ratio has 20 liters water
1:2 ratio has 40 liters water
The amount of water added is 40 - 20 = 20 liters
