your number was 12.
let x be the number:
(x * 2) + 50 = 74
To solve for x, we need to reverse what was done to get the answer of 74.
Since 50 was added to arrive at 74, we deduct 50 from 74.
74 - 50 = 24
We then divide 24 by 2 to get the original number.
24/2 = 12.
Your number was 12.
To check:
(12 * 2) + 50 = 74
24 + 50 = 74
74 = 74
Answer:
113.1
Step-by-step explanation:
Write down the equations on the top of your paper; it could help you throughout your homework.
The equation for circumference is 2 times pi, times the radius.
The Radius is the diameter times two.
2 times 9=18, so therefore the radius is 18.
Once you have that done, just put in your calculator 2 times pi times 18.
X=5, if that’s what you’re solving for

Answer:
214°
Step-by-step explanation:
The arc subtending an angle at the centre are equal, that is
arc ED = 90° and
arc DF = 360° - (90 + 146)° = 360° - 236° = 124°
Thus
arc EDF = arc ED + arc DF = 90° + 124° = 214°
