Answer:
20 grams
Step-by-step explanation:
Let g represent the grams of solution that were replaced. Then the amount of alcohol in the mix is ...
16%·(120 -g) +100%·g = 30%·120
19.2 +0.84g = 36.0 . . . . simplify
0.84g = 16.8 . . . . . . . . . .subtract 19.2
g = 20 . . . . . . . . . . . . . . .divide by 0.84
20 grams of solution were taken out and replaced.
This the equation you will need to use (the Pythagorean Theorem)

when you put the numbers in for the variables given it will look like this

3 squared equals 9 and 4 squared equals 16:

so side c is 25 units

Answer:
( 10 x + 10 ) = 110
Step-by-step explanation:
As you can see this following diagram shown a vertical angles which are angles that are opposite of each other when two lines cross. You can also see it kind of look like a "x". Vertical angles also means that they have the same angle measure. A example is if this angle is "110" then the other sides equal to "110''.
Hence, the equation we can be used to solve for x in the following diagram is:
( 10 x + 10 ) = 110

The answer will be 2,900 HOPES this helps. :)
If it is delayed by a month, a possible adjustment to the equation could look something like this:
S = 2(t-1)^2 + 100
These type of transformations are called horizontal shifts, aka "shift along the x-axis". So the answer is A.
