Answer:
Equation: 139 + 3x + (5x - 10) + (10x - 9) + 3x = 540 (not simplified, see below for simplified)
x = 20
Step-by-step explanation:
If the sum of the angles is 540°, then that means you add them up to get 540°.
139 + 3x + (5x - 10) + (10x - 9) + 3x = 540
129 + 8x + (10x - 9) + 3x = 540
120 + 18x + 3x = 540
120 + 21x = 540
21x = 420
x = 20
(n+1)x 2=10
2n+2=10
2n=8
n=4
You need to create common denominators and then add and then subtract to get 22/48
Given that t<span>he
average commute time to work (one way) is 25 minutes according to the
2005 american community survey. if we assume that commute times are
normally distributed and that the standard deviation is 6.1 minutes,
what is the probability that a randomly selected commuter spends less
than 18 minutes commuting one way
The probability that a randomly selected number from a normally distributed dataset with a mean of μ and a standard deviation of σ is less than a value, x, is given by:

This shows the multiplication between 3 and 23. So your word problem will have to show that. Jean buys three packs of gum. Each pack has 23 pieces. How many pieces of gum does Jean have in total? :)
