34kurt

Answer:

D. The graphs of the equations intersect each other at two places.

Step-by-step explanation:

The definition of a solution of a system of two equations in two variables is a point where the graphs intersect. A system of equations having graphs that intersect each other will have as many solutions as there are intersection points. If the graphs intersect in two places, there will be two solutions.

In a chemistry lab, you have 2 vinegars. One is 5% acetic acid, and one is 6.5% acetic acid. You want to make 200 ml of a vinega

Iteru [2.4K]

We have 5% and 6.5% acetic acid solutions and we need 200 ml of 6% acetic acid.
Set up two equations:
f means 5% and s means 6.5%
A) f + s = 200
B) .05f + .065s = (.06 * 200)
Multiplying equation A by -.05
A) -.05f -.05s = -10
B) .05f + .065s = 12 then adding both equations:
.015s = 2
 we need 133.33 ml of 6.5% acetic acid and
66.67 ml of 5% acetic acid solution.

36 students have traveled outside of the United States, when there are total 120 sixth graders.

Explanation

The number of students traveled outside of the United States is 9 when there is total 30 sixth graders. So, the ratio of the student traveled to the total students will be $9: 30 = 3: 10$

Now there are total of 120 sixth graders in the school and lets assume the number of students traveled outside the United states is $x$ . That means the ratio...
