Answer:
Yes
Step-by-step explanation:
1 dozen = 12
dozen = 2.5 * 12 = 30
She has 30 balloons, so yes, there are enough balloons.
Answer: and {x: x is less than 13/6}
Explanation:
We have given a statement 12 times a number x gives 12x
subtracted from 34 gives 34 -12x
greater than 8 finally gives 34 - 12x>8
Now, to find solution for 34 -12x >8
we simplify the equation -12x >-26
x< 13/6
Now the solution set for the inequality is {x: x is less than 13/6}
and interval form is x belons to
