What is the simplified form of the quantity of x plus 7, all over the quantity of 6 − the quantity of x plus 5, all over the qua
vlabodo [156]

For this case we must simplify the following expression:

\frac {\frac {x + 7} {6- (x + 5)}} {x + 3}

We must apply double C:

\frac {(x + 7) (x + 3)} {6- (x + 5)} =

We apply distributive property in the numerator:

\frac {x ^ 2 + 3x + 7x + 21} {6- (x + 5)} =\\\frac {x ^ 2 + 10x + 21} {6- (x + 5)} =

In the denominator we have by law of signs:

- * + = -\\\frac {x ^ 2 + 10x + 21} {6-x-5} =

Different signs are subtracted and the sign of the major is placed:

\frac {x ^ 2 + 10x + 21} {- x + 1}

ANswer:

\frac {x ^ 2 + 10x + 21} {- x + 1}

The table below shows the data for a random sample of fish that were collected from and later released into a lake: type of fish
Gwar [14]
You were given the data as statistics so that you can predict the number of a certain type of fish through ratio and proportion. The main focus here is then number of bluegill fish. From the given statistics, the number is 87. The total number of fishes at that time was 52+61+87 = 200. So, assuming that this composition is uniform in the said lake. We can then use the ratio from the given statistics to know the proportion of bluegills to the total fishes. Hence, we equate the two ratios:

87/200 = x/800

where x is the number of bluegills among the 800 total fishes that is in proportion to the gathered statistics. Solving for x, we determine the answer to be

x = 348
