Answer:
x = 132°
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
A hexagon has 6 sides, thus n = 6
sum = 180° × 4 = 720°
Sum the given interior angles and equate to 720
x + 108 + 113 + 132 + 75 + 160 = 720, that is
x + 588 = 720 ( subtract 588 from both sides )
x = 132°
Answer: ( 1.26 x 10 ^ 5 ) / ( 2.8 x 10 ^ 4 )
= 4.5 times bigger
Answer:
1/3 is the y intercept
Step-by-step explanation:
f(x) = -2/9x + 1/3
This is written in slope intercept form
y = mx+b where m is the slope and b is the y intercept
-2/9 is the slope and 1/3 is the y intercept
498-53=445
445/2=222.5
222.5+53=275.5
so there were 222.5 student tickets sold
to check: 275.5 + 222.5+498
The error was on step 3, and she found the error on step 4.
Explanation: on step 3, the 12 was supposed to be a negative, but it wasn’t. So she solved it on step 4, and added the negative sign.
