Answer:
16 = x
Step-by-step explanation:
A triangle has 180 degrees. Use this to solve for x
180=(9x-8)+(x+2)+(x+10)
180 = 9x + x + x - 8 + 2 +10
180 + 8 -2 - 10 = 11 x
176 = 11x
176/11 = x
16 = x
Answer:
12
Step-by-step explanation:
To find the mean of a set of numbers, add all the numbers together. Then, divide the sum by how many numbers you had to begin with.
Add the numbers together:
10 + 12 + 15 + 11
= 48 This is the sum of the data
Count how many numbers you had:
10, 12, 15 and 11 are FOUR numbers (amount of data).
Divide the sum of the data by the amount of data.
48 ÷ 4 = 12 This is the mean
The mean of 10, 12, 15, 11 is 12.
Basically you just have to do either $18/4 or $27/6 which gets you to 4.5 which is the unit rate
Answer:
{ x | -3 <= x < +1 }
Step-by-step explanation:
We note that the graph occupies from x=-3 to x=+1, while -3 is a value included (endpoint is solid), and +1 is excluded (endpoint hollow).
Thus the domain is { x | -3 <= x < +1 }
