- Pythagorean Theorem: a² + b² = c²
Step-by-step explanation:
<u>Step 1: Define</u>
Leg <em>a</em> = <em>x</em>
Leg <em>b</em> = 64
Hypotenuse <em>c</em> = 80
<u>Step 2: Solve for </u><em><u>x</u></em>
- Substitute: x² + 64² = 80²
- Isolate <em>x</em> term: x² = 80² - 64²
- Exponents: x² = 6400 - 4096
- Subtract: x² = 2304
- Isolate <em>x</em>: x = √2304
- Evaluate: x = 48
Answer:
infinite solutions
Step-by-step explanation:
4x=4x
Divide each side by x
4x/x = 4x/x
4 =4
This is always true,no matter what value we put in for x. So there are infinitely many solutions to the equation.
Choice A has the lowest unit rate.
Choice A: 0.298 per oz.
Choice B: 0.2991 per oz.
You want to know how much each individual ounce costs, so you divide the price by the ounces to see how much each ounce costs.
1.49 divided by 5 is 0.298
3.59 divided by 12 is 0.29166...
