Step-by-step explanation:
1. you can write an equation to represent the word problem
20-(2.10+0.9x)
20-(2.10+0.9(13)
20-(2.10+11.7)
20-(13.8)
6.2
Answer:
Equation is
0.125 gallons of the 35% acid solution Eli should add.
Step-by-step explanation:
Given : Eli wants to combine 0.5 gallon of a 10% acid solution with some 35% acid solution to make a 15% acid solution.
To find : Equation can you use to determine how many gallons of the 35% acid solution Eli should add?
Solution :
Let x be the gallons of the 35% acid solution.
According to question,
For 0.5 gallon of a 10% acid solution =
For x gallon of a 35% acid solution =
For (0.5+x) gallon of a 15% acid solution =
The equation form is
Solving the above equation,
Therefore, 0.125 gallons of the 35% acid solution Eli should add.
The equation is
The expression would be (5*6)+(5*6)=x
or you could shorten it and do (10*6)=x
