Answer:
109 took physics and 392 took Trigonometry
Step-by-step explanation:
Answer:
- 21 hours in May, 63 hours in June
Step-by-step explanation:
<h3>Set up equations</h3>
<h3>Solve by substitution, fin the value of j</h3>
- 1/3j + j = 84
- 4/3j = 84
- j = 84*3/4
- j = 63
<h3>Find m</h3>
- m + 63 = 84
- m = 84 - 63
- m = 21
Answer:
x = ±2√15
General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
- Equality Properties
<u>Algebra I</u>
Step-by-step explanation:
<u>Step 1: Define</u>
x² = 60
<u>Step 2: Solve for </u><em><u>x</u></em>
- Square root both sides: x = ±√60
- Simplify: x = ±2√15
<u>Step 3: Check</u>
<em>Plug in both solutions of x to verify it's a solution.</em>
x = 2√15
- Substitute: (2√15)² = 60
- Evaluate: 4 · 15 = 60
- Multiply: 60 = 60
x = -2√15
- Substitute: (-2√15)² = 60
- Evaluate: 4 · 15 = 60
- Multiply: 60 = 60
Here we see that both solutions do indeed work.
∴ x = ±2√15 are both solutions to the equation.
