Answer:
60
Step-by-step explanation:
AOC= AOB+ BOC
104= 7x+30 +9x+42
104= 16x+72
subtract both sides by 72
104-72=16x
32=16x
divide both sides by 16
x=2
BOC= 9(2) +42
BOC= 60
Answer:
X= 18
Step-by-step explanation:
24/4=6 x 3= 18
Pretty sure it might be either B or C... No entirely sure...
Rational: Any number that can be expressed as a fraction (or a ratio.)
Irrational: Not rational, any number that can't be written down as a fraction. Some examples include

An inequality is used to show two values that are different and to show that the two values are unequal.
<h3>What is an Inequality?</h3>
This refers to the mathematical relation that is used to show the comparison between two numbers that are unequal.
We can note that because there is a previous record, for a person to beat the record, he would have to perform better than the record and be faster than the previous record holder.
Therefore, if a record of Amelia was given, this would be used to find the relation between her record and the current record of 37 sit-ups and how many weeks of training would be needed to break the record.
Hence, we can see that the question is incomplete so I gave you a general overview to help you get a better understanding.
