Answer: The answers to the first page
Step-by-step explanation:
Question 1
Divide both sides by 6. Since 6 is positive, the inequality direction remains the same.
6
−48
>x
Divide −48 by 6 to get −8.
−8>x
Swap sides so that all variable terms are on the left-hand side. This changes the sign direction.
x<−8
Question 2
−3x+8>11
Subtract 8 from both sides.
−3x>11−8
Subtract 8 from 11 to get 3.
−3x>3
Divide both sides by −3. Since −3 is negative, the inequality direction is changed.
x<
−3
3
Divide 3 by −3 to get −1.
x<−1
Question 3
15x+60>240
Subtract 60 from both sides.
15x>240−60
Subtract 60 from 240 to get 180.
15x>180
Divide both sides by 15. Since 15 is positive, the inequality direction remains the same.
x>
15
180
Divide 180 by 15 to get 12.
x>12
Question 4
3rd answer choice
Question 5
First, let's calculate how many miles he has left.
80 - 14 = 66
Now, to figure out how many miles a day in 6 days, divide.
66/6 = 11
Xavier should bike 11 miles on each of the 6 remaining days.
