Modeling with Linear Equations
In this section, you will use algebra to solve problems that occur in real-life situations. The process of translating phrases or sentences into algebraic expressions or equations is called
Average in 1 day is 7.1 pounds
So for a week about
49.7 pounds of garbage thrown away for each person
Answer:
try using the point (1,13)
Step-by-step explanation: I pulled up and online graph to help and the distance from A to B is 7/2. So then you would do B, plus 7/2. If that's wrong, I'm sorry, but i tried.
If 3/10 cup is 2/5 full, then the bowl holds:
(3/10) / (2/5)
(3/10)/(2/5) = 3/10 * 5/2 = 15/20 = 3/4
The bowl holds 3/4 of a cup
Answer:
90 and 30 liters
Step-by-step explanation:
1) if solution of 20% is 'x' and of 60% is 'y' liters, then
2) the pure chlorine is: for solution of 20% - 0.2x, for solution of 60% - 0.6y and
3) the mix of the two solutions is 120=x+y.
4) using these items it is possible to make up the system of two equations:
5) finally, x=90 liters of 20%; y=30 liters of 60% solution.
