Answer:
$4.86
Step-by-step explanation:
we must found cost of 1 slice of cheese first.
11 slices of cheese are $2.97
1 slice of cheese is $2.97÷11
18 slices of cheese are $2.97÷11×18 = $4.86
or you can calculated 1 slice of cheese
2.97÷11 = $0.27 and 0.27×18 = $4.86
both methods are correct

Step-by-step explanation:
Answer:
x = infinite amount of solutions
General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
- Equality Properties
Step-by-step explanation:
<u>Step 1: Define equation</u>
3(x + 10) + 6 = 3(x + 12)
<u>Step 2: Solve for </u><em><u>x</u></em>
- Distribute 3: 3x + 30 + 6 = 3x + 36
- Combine like terms: 3x + 36 = 3x + 36
- Subtract 36 on both sides: 3x = 3x
- Divide 3 on both sides: x = x
Here we see that <em>x</em> does indeed equal <em>x</em>. We can plug in any number <em>x</em> and it would render the equation true.
∴ x = infinite amount of solutions
