Answer:
25 minutes 42 seconds
Step-by-step explanation:
The tub will fill at the rate of ...
2.25 gal/min - 0.50 gal/min = 1.75 gal/min
It will take ...
45 gal/(1.75 gal/min) ≈ 25.714 min
for the tub to fill.
You can shower for about 25 minutes 42 seconds.
What given data? It’s just lines, what’s the data before?
Answer:
r = 4
General Formulas and Concepts:
<u>Pre-Alg</u>
- Order of Operations: BPEMDAS
- Equality Properties
Step-by-step explanation:
<u>Step 1: Define equation</u>
-5 + 22 = r - 4 + 3r + 5
<u>Step 2: Solve for </u><em><u>r</u></em>
- Combine like terms: 17 = 4r + 1
- Subtract 1 on both sides: 16 = 4r
- Divide 4 on both sides: 4 = r
- Rewrite: r = 4
<u>Step 3: Check</u>
<em>Plug in r to verify it's a solution.</em>
- Substitute: -5 + 22 = 4 - 4 + 3(4) + 5
- Add/Subtract: 17 = 3(4) + 5
- Multiply: 17 = 12 + 5
- Add: 17 = 17
the answer is C. because it is the only one that does not contain a common factor :)
