The solution of the inequality is x < -9
<h3>How to solve the inequality for x?</h3>
The inequality expression is given as:
-11 < -18- 7/9x
Add 18 to both sides of the inequality
18 - 11 <- 7/9x
Evaluate the difference
7 <- 7/9x
Multiply both sides by -9/7
-9 < x
Rewrite as:
x < -9
Hence, the solution of the inequality is x < -9

So 72 pencils and 24 calculators
so greates number of identical calculators
this means
what is the biggest number that we can divide 72 and 24 by and get a whole number
this is called the GCM or greatest common multipule
to find the GCM, you factor 72 and group the like ones
72=2 times 2 times 2 times 3 times 3
24=2 times 2 times 2 times 3
so the common group is 2 times 2 times 2 times 3 or 24
so the greates number of packs is 24
so pencils
72 divided by 24=72/24=3
3 pencils per pack
24 divided by 24=24/24=1
1 calulator per pack
answer is 3 pencils and 1 calculator per pack
92% is 92 out of 100
therefore simply put 92 over 100 and simplify it.
Meaning divide top and bottom into 2. Then you get your answer, if needed simplify again.
His average rate is 120 meters per minute.
