If you give me answers i can give you the right one
Answer:
Given:
f(x) = 3x + 2
g(x) = 2x – 5
f(2)+g(1)
----------------------------------------------------------------
Above we have three clues that we got from the question.
First, substitute the value of f(2) for f(x)
3(2)+2
6+2
8
Second, substitute the value of g(1) for g(x)
2(1)-5
2-5
-3
Now we have to add the f(x) value which is 8 and the g(x) value which is -3.
8+-3
5
Your final answer would be 5.
Answer:
Step-by-step explanation:
not really the answer but there’s an app called photo math. perfect for math equations it didn’t let me put it, but download it it’s free and it’s tell you what to do. only works for math.
Let A be the amount of 100% acid.
100A+20*(6)=40*(A+6)
100A+120=40A+240
60A=120
A=2 gallons
