I believe it is neither
For one if you plug in either of them the first one is going to be negative 3. But if you use the second one then your answer would be -3+12= -10 but -3+12 is 9 so I would go with neither because I don't see how it's both
Answer:
x - 10 = 75, or the second one
Step-by-step explanation:
The first, third, and fourth one is all equations that can help determine the measure of angle C, not D.
Hope this helps!!
Plz let me know if I'm wrong...
Answer:
Step-by-step explanation:
20%. 53.17 times .8 is 42.54 meaning there's a 20% decrease
Answer:
r = 1
Step-by-step explanation:
Step 1: Write equation
-3r + 18 = 15r
Step 2: Solve for <em>r</em>
- Add 3r to both sides: 18 = 18r
- Divide both sides by 18: 1 = r
- Rewrite: r = 1
Step 3: Check
<em>Plug in r to verify it's a solution.</em>
-3(1) + 18 = 15(1)
-3 + 18 = 15
15 = 15
