the equation 2x-4-1+x would be the answer
Because 2x+x = 3x and -4-1 = 5, the result would be 3x-5
The expression we need to solve is:

To solve this problem, we need to not that we can simplify the fraction 2/10 by dividing both number by 2:
Question 5, x could be either 6 or -1.
Answer:
200 mL
Step-by-step explanation:
If x is the volume of solution B:
0.06 (500) + 0.20 x = 0.10 (500 + x)
30 + 0.20 x = 50 + 0.10 x
0.10 x = 20
x = 200
Answer:
1/15
