Austin wants to make twelve gallons of 46% acid solution by mixing together 65% acid solution and a
1 answer:
Answer:
Austin should use 8.2 gallons of 65% acid solution and 3.8 gallons 5% acid solution
Step-by-step explanation:
Let
x ----> the gallons of 65% acid solution needed
y ----> the gallons of 5% acid solution needed
Remember that
we know that
-----> equation A
-----> equation B
Solve the system by graphing
The solution is the intersection point both graphs
using a graphing tool
The solution is (8.2,3.8)
therefore
Austin should use 8.2 gallons of 65% acid solution and 3.8 gallons 5% acid solution

Step-by-step explanation:
This is a vocabulary problem, identifying the names of things on a diagram.
Angles are "interior" when they are between the "parallel" lines. They are "exterior" when they are outside those lines. They are "alternate" if they are on opposite sides of the transversal, and "same side" if they are not.
They are "vertical" if they share a vertex and have opposite rays for sides, and they are "corresponding" if they are in the same quadrant of the intersection of crossing lines. (1, 5, 9, 13 are "corresponding", for example.)
