Answer: x = 10
Step-by-step explanation:
The sum of all interior angles in a polygon add up to 360°
Meaning to find X we grab those numbers/variables and make them equal to 360°. This will give us an equation.
106 + 94 + 135 + x + ( x + 5 ) = 360
335 + x + x + 5 = 360
340 + 2x = 360
subtract 340 from both sides
2x = 20
Divide by 2
x = 10
Now solve the angle equations to find their angle.
( 10 + 5 ) = 15
x = 10
Now to check if it's right add them together
106 + 94 + 15 + 10 + 135 = 360 ( ITS CORRECT )
Answer:
34 hours
Step-by-step explanation:
2:25 = x:425
25/2 = 12.5
425/12.5 = 34
so it is 34:425
She will need to read for 34 hours to read 425 pages
Answer:
x = 121.5
Step-by-step explanation:
- Write it out: 6x = 729
- Divide each side by 6 to cancel out the 6 next to x. It should now look like this: x = 121.5
