Step-by-step explanation:
<u>Step 1: Set Up</u>
Let's let our number be set by variable <em>n</em>.
We add 7 to it: n + 7
We then double that entire expression: 2(n + 7)
That expression is equal to 82.8: 2(n + 7) = 82.8
<u>Step 2: Solve for </u><em><u>n</u></em>
- [Division Property of Equality] Divide 2 on both sides: n + 7 = 41.4
- [Subtraction Property of Equality] Subtract 7 on both sides: n = 34.4
∴ Caroline's original number is 34.4.
Answer:
n = 17°
Step-by-step explanation:
The two angles are split by a 90° angle on a 180° line. This means that 44 and 3n - 5 must add up to 90.
3n - 5 + 44 = 90
Solve out left side
3n + 39 = 90
Subtract 39 from both sides
3n = 51
Divide both sides by 3
n = 17
