When you're looking to simplify a fraction, the best thing to do is to find a common factor between the two numbers.
In this case, 10 is a common factor, so therefore, divide both sides by 10.
30/10= 3
40/10= 4
Therefore, the fraction in its simplest form is 3/4

Answer:
Primates
Step-by-step explanation:
It is the most specific because homo, hominidae and O sapiens fall under the catogory of primates
$89.08 divided by 4 is $22.27, aka the price of one shirt
Answer:
Rate of depreciation per year is 4310 $/ year and the depreciation schedule is given below.
Step-by-step explanation:
According to the question,
since, it is straight-line depreciation,
rate of depreciation per year =
$/year
= 4310 $/ year
So we can prepare the following table. (year = 0 for the base period)
Year Depreciation Accumulated Book value
expense depreciation
( in $) (in $) (in $)
0 0 0 21920
1 4310 4310 17610
2 4310 8620 13300
3 4310 12930 8990
4 4310 17240 4680
Step One
Put the right side over a common denominator.

Step Two
Remove the brackets on the numerator in the last equality.
Step three.
This will seem kind of odd but take out the common factor (x) in the first two terms of the numerator.

Step Four
What you do next comes up very frequently in your second or third calculus course.
You have to notice that there are no xs in the numerators on the left side of the original expression
Therefore you have to make a - b = 0 so that the xs disappear on the right.
a - b =0
a = b
Step Five
Find a
a is all by itself on the numerator of the final result.
The original question has a 1 in the numerator. Therefore a = 1
Step Six
Solve for b
a = b
1 = b Answer
