Answer:
7. Ten days were above 70 degrees
8. Approximately 33% of the days were 69 degrees or lower
9. Approximately 8 days would most likely be above 80 degrees
Step-by-step explanation:
The very first thing I did is I put the values in order, ranging from 66 to 85. Then, I counted the number of days where the high temperature was greater than 70 degrees (which ended up being 10).
Five of the days were 69 degrees or lower, so I divided that by fifteen to get 33.33333% (which you can round down as 33%).
Then, as four of these fifteen days had temperatures greater than 80 degrees, I divided four by fifteen and got approximately 26.7%. Multiplying 30 by 0.267, I get 8.01 (which you can just round down as 8).

Answer:
Question 1 is 14:10
Question 2 is 8:15
Step-by-step explanation:
Answer: 12 months (1 year)
We know that Alision gains $29.26 each month. She wants to buy a stereo for $339.12
You want to divide $339.12 with $29.26 to find the total months.
339.12 / 29.26 = 11.6
CHECK:
You want to round up, since she needs the money to buy a stereo. She's allowed to have more money.
29.26 * 12 = 351.12
It will take Alision 12 months (1 year) to buy her stereo.
Answer:
Simplifying
7x + -2(x + 1) = 6x + 14
Reorder the terms:
7x + -2(1 + x) = 6x + 14
7x + (1 * -2 + x * -2) = 6x + 14
7x + (-2 + -2x) = 6x + 14
Reorder the terms:
-2 + 7x + -2x = 6x + 14
Combine like terms: 7x + -2x = 5x
-2 + 5x = 6x + 14
Reorder the terms:
-2 + 5x = 14 + 6x
Solving
-2 + 5x = 14 + 6x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-6x' to each side of the equation.
-2 + 5x + -6x = 14 + 6x + -6x
Combine like terms: 5x + -6x = -1x
-2 + -1x = 14 + 6x + -6x
Combine like terms: 6x + -6x = 0
-2 + -1x = 14 + 0
-2 + -1x = 14
Add '2' to each side of the equation.
-2 + 2 + -1x = 14 + 2
Combine like terms: -2 + 2 = 0
0 + -1x = 14 + 2
-1x = 14 + 2
Combine like terms: 14 + 2 = 16
-1x = 16
Divide each side by '-1'.
x = -16
Simplifying
x = -16
