Plan A = 9 +0.17x
Plan B = 21 +0.12x
9+0.17x = 21+0.12x
X=240
9+0.17(240)=49.8
21+0.12 (240)=49.8
240 minutes and cost $49.80 each
Whole numbers cannot have fractional components and 2/15 is a proper fraction; therefore, it cannot be made into a mixed number either

- All angles in a triangle add up to 180°
Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify and set up</em>
m∠A = 31°
m∠B = θ
m∠C = 45°
θ + 31° + 45° = 180°
<u>Step 2: Find θ</u>
- Add: θ + 76° = 180°
- [Subtraction Property of Equality] Subtract 76° on both sides: θ = 104°
