Answer:
Third bar graph.
Step-by-step explanation:
Given : 5x + 7.5 = 15.
To find : Which bar diagram represents the equation.
Solution : We have given 5x + 7.5 = 15
In the equation we can see sum of 5x and 7.5 is 15 .
By the bar graph combination box of 5x and box of 7.5 is equal to the box of 15.
Then Third bar graph represent the equation .
Two pink boxes of 5x and 7.5 and one blue box of 15.
Therefore, Third bar graph.
Answer:
x = 17 $20 bills
y = 30 $5 bills
General Formulas and Concepts:
- Order of Operations: BPEMDAS
- Multivariable Systems
Step-by-step explanation:
<u>Step 1: Define variables</u>
x = # of $20 bills
y = # of $5 bills
<u>Step 2: Set up systems of equations</u>
<u />
<u />
<u />
<u>Step 3: Solve for </u><em><u>x</u></em>
- Rewrite:

- Substitute:

- Distribute 5:

- Combine like terms:

- Subtract 235 on both sides:

- Divide both sides by 15:

By solving for <em>x</em>, we now know that we have 17 $20 bills.
<u>Step 4: Solve for </u><em><u>y</u></em>
- Define: x + y = 47
- Substitute: 17 + y = 47
- Subtract 17 on both sides: y = 30
Now we know that we have 30 $5 bills.
