Answer:
2 hours
Step-by-step explanation:
variable x = hours
fix it fast: 25 + 50x
do it right: 35 + 45x
25 + 50x = 35 + 45x
subtract 45x from both sides
subtract 25 from both sides
(this action cancels out 45x on the right side and 25 on the left side so you can combine like terms)
50x - 45x = 35 - 25
5x = 10
divide by 5 on both sides
x = 2
In order to estimate this problem we must first estimate the two numbers involved.
137,638 rounds up to 138,000.
Since the 6 is bigger than 5 it makes the number 7 round up to 8
Now..
52,091 rounds out to 52,000
Since the number to the left of the 2 is not bigger than 5 then it stays the same at 52,000
Now we have to add our estimated numbers.
138,000 + 52,000 = 190,000
Your answer is 190,000
Good Luck! :)

Answer:
Option 2 or B
Step-by-step explanation:
B, if you look at the data table, you can notice that x and y are decreasing (therefore going down). I hope this helps?
Answer:
All values along the x-axis in the shaded regions.
Step-by-step explanation:
The solution set of the compound inequality is any number less than 2 and greater than 7. This means its all the numbers on the number line from 1.99999 to 0 to -9 to -1000 and so forth. And it's also any number greater than 7 including 7.01 to 1000 to 1,000,000. See the graph below to visually see the solution. The solution are all the numbers along the x-axis in the shaded regions.
Step-by-step explanation:
