Answer:
$8.30
Step-by-step explanation:
7.99 + 4% = 8.30
You will have to follow PEMDAS. Which means you will do what's in the parentheses first. 1+4=5
5^2+3*5 is your new equations.
Next you will do the exponents.
5 Squared is 25.
25+4+5
Then you will do multiplications
25+(3*5)= ?
25+15= ?
25+15= 40.
Answer:
x = 52
General Formulas and Concepts:
Order of Operations: BPEMDAS
Step-by-step explanation:
<u>Step 1: Define equation</u>
3x - 17 = 2x + 35
<u>Step 2: Solve for </u><em><u>x</u></em>
- Subtract 2x on both sides: x - 17 = 35
- Add 17 to both sides: x = 52
<u>Step 3: Check</u>
<em>Plug in x to verify it's a solution.</em>
- Substitute: 3(52) - 17 = 2(52) + 35
- Multiply: 156 - 17 = 104 + 35
- Subtract/Add: 139 = 139
Well, there's many equations that represent real world situations. These equations we use a lot in engineering. For example, something fundamental is that we can calculate the velocity of something by knowing it's acceleration by taking the integral of the acceleration.
