Find the number of boxes needed, x, for 42 granola bars. ​
serg [7]

The question is incomplete:

Find the number of boxes needed, x, for 42 granola bars. ​

The table with the information is attached.

Answer:

The number of boxes needed for 42 granola bars is 7.

Step-by-step explanation:

Since the table shows that for 12 granola bars 2 boxes are needed, you can use a rule of three with this information to find the number of boxes needed for 42 granola bars:

12 granola bars  → 2 boxes

42 granola bars →      x

x=(42*2)/12

x=84/12

x=7

According to this, the answer is that the number of boxes needed for 42 granola bars is 7.

Solve the system of linear equations by graphing <br> y=1/3x+5<br> y=2/3x+5<br> What is the solution
Tamiku [17]

Answer:

We have the system of equations:

y=1/3x+5

y=2/3x+5

To solve it graphically, we need to graph both lines and see in which point the lines intersect.

You can see the graph below, and you can see that the lines intersect in the point (0, 5)

Now, we can also solve this analytically.

We can use the fact that for the solution, we need y = y.

Then we can write:

(1/3)*x + 5 = (2/3)*x + 5

First, we can subtract 5 in both equations to get:

(1/3)*x = (2/3)*x

This only has a solution when x = 0.

Replacing x = 0 in one of the equations, we get:

y = (1/3)*0 + 5 = 5

Then the solution is x = 0, and y = 5, as we already could see in the graph.
