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.
If you mean 'she' wants to buy 2/4 of the candy bars at the store and there are 12 candy bars in the store then:
2/4 is the same as 1/2
Half of 12? 6
She would buy 6 candy bars.
Answer:
is there an equation for this or simple math?
To write an expression, we often have to interpret a written phrase. For example, the phrase “6 added to some number” can be written as the expression x + 6, where the variable x represents the unknown number.
