Answer:
x > -4
Step-by-step explanation:
Inequalities like these are solved the same way equations are solved, except when multiplying both sides you flip the less than/greater than sign:
3x + 7 > -x -9
3x + 7 - 7 > -x -9 -7 Subtract 7 from both sides
3x > -x -16
3x + x > -x -16 + x add x to both sides
4x > -16
>
divide both sides by 4
x > -4
In this case the inequality sign did not have to be flipped since we never multiply both sides by a negative number.

Answer:
44 in
Step-by-step explanation:
The circumference of the tire will be the same as the distance the unicycle moves in one complete revolution.
Find the circumference with the formula C =
d, where d is the diameter
Plug in the values:
C =
(14)
C = approx. 44 in
