Subtract 4 from 1/6 of 42
2 answers:
Subtract 4 from of 42, the answer is 3.
Subtract 4 from of 42 can also be expressed as: (
x 42 ) - 4
Therefore, you have:
= ( x 42 ) – 4 (since 42 and 6 can divide each other, then we can evaluate the expression)
Therefore, you have:
= (1 x 7) – 4
= (7) – 4
= 7 – 4
= 3
Therefore, if you subtract 4 from of 42, the answer is 3.
Notably, the question was solved using the rule of BODMAS.
It represents Bracket, order, division, multiplication, addition, subtraction.
Significantly we derived the solution by using multiplication, division, and subtraction. Also, it is important to know that 1 sixth can be expressed as and 1 sixth of 42 is the same as
x 42.

Explanation:
Problems 1, 2, and 5 are exponential functions of the form where b is the base of the exponent and 'a' is the starting term (when x=0).
If 0 < b < 1, then the exponential function decreases or decays. Perhaps a classic example would be to study how a certain element decays into something else. The exponential curve goes downhill when moving to the right.
If b > 1, then we have exponential growth or increase. Population models could be one example; though keep in mind that there is a carrying capacity at some point. The exponential curve goes uphill when moving to the right.
In problems 1 and 5, we have b = 2 and b = 1.1 respectively. We can see b > 1 leads to exponential growth. I recommend making either a graph or table of values to see what's going on.
Meanwhile, problem 2 has b = 0.8 to represent exponential decay of 20%. It loses 20% of its value each time x increases by 1.
---------------------
Problems 3 and 4 are linear functions of the form y = mx+b
m = slope
b = y intercept
This b value is not to be confused with the previously mentioned b value used with exponential functions. They're two different things. Unfortunately letters tend to get reused.
If m is positive, then the linear function is said to be increasing. The line goes uphill when moving to the right.
On the other hand if m is negative, then we go downhill while moving to the right. This line is decreasing.
Problem 3 has a negative slope, so it is decreasing. Problem 4 has a positive slope which is increasing.
