Answer:
The number of pizzas sold during A-
lunch is 64
Step-by-step explanation:
Let us solve the question using the ratio method
∵ The ratio of pizza to nachos sold during A-lunch is 4 to 3
∵ There were 48 nachos sold
→ By using the ratio method
→ Pizza : Nachos
→ 4 : 3
→ x : 48
→ use the cross multiplication
∵ x × 3 = 4 × 48
∴ 3x = 192
→ Divide both sides by 3
∵ 
= 
∴ x = 64
∴ The number of pizzas sold during A-
lunch is 64
3x5=$15
15+10=$25 total to spend
He spends 12.75+8.5= $21.25
25-21.25=$3.75 left

Answer:
x = 41/3
General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
- Equality Properties
Step-by-step explanation:
<u>Step 1: Define equation</u>
7(1x - 3) = 4(x + 5)
<u>Step 2: Solve for </u><em><u>x</u></em>
- Simplify: 7(x - 3) = 4(x + 5)
- Distribute: 7x - 21 = 4x + 20
- Subtract 4x on both sides: 3x - 21 = 20
- Add 21 on both sides: 3x = 41
- Divide 3 on both sides: x = 41/3
<u>Step 3: Check</u>
<em>Plug in x to verify it's a solution.</em>
- Substitute: 7(1(41/3) - 3) = 4(41/3 + 5)
- Multiply: 7(41/3 - 3) = 4(41/3 + 5)
- Subtract/Add: 7(32/3) = 4(56/3)
- Multiply: 224/3 = 224/3
Here, we see that 224/3 is indeed equivalent to 224/3. ∴ x = 41/3 is a solution to the equation.
And we have our final answer!
