Answer:
30 boxes
Step-by-step explanation:
1 box = 1 pound
x = 30 pound
30 Cross multiplied with 1
= 1 *30 =30
therefore: Julie can fill 30 boxes

Answer:
B. 1/2
Step-by-step explanation:

If we plug in 0 for z, we get 0/0. Apply l'Hopital's rule.

Now when we plug in 0 for z, we get:

- Solving systems of equations by graphing
Step-by-step explanation:
<u>Step 1: Define Systems</u>
16x + 14y = 8
-63x - 14y = 133
<u>Step 2: Solve for </u><em><u>x</u></em>
<em>Elimination</em>
- Combine 2 equations: -47x = 141
- Divide -47 on both sides: x = -3
<u>Step 3: Solve for </u><em><u>y</u></em>
- Define original equation: 16x + 14y = 8
- Substitute in <em>x</em>: 16(-3) + 14y = 8
- Evaluate multiplication: -48 + 14y = 8
- Add 48 on both sides: 14y = 56
- Divide 14 on both sides: y = 4
<u>Step 4: Graph Systems</u>
<em>Check the solution set.</em>
A graph is a way to represent a lot of data in such a visual format. The graph for the given situation can be drawn as shown below.
<h3>What is a graph?</h3>
A graph is a way to represent a lot of data in such a visual format that it is easy for the user to understand the complete information in one go. Usually, the line of the graph is a function that follows the graph.
The graph for the given situation can be drawn as shown below, where the x-axis represents the number of pounds of rice scooped and purchased from a bulk bin at the grocery store and the y-axis represents the total cost of the rice.
