6 0

Answer:

x = 49

Step-by-step explanation:

Given

$\frac{x-16}{x+6}$ = $\frac{3}{5}$ ( cross- multiply )

5(x - 16) = 3(x + 6) ← distribute parenthesis on both sides

5x - 80 = 3x + 18 ( subtract 3x from both sides )

2x - 80 = 18 ( add 80 to both sides )

2x = 98 ( divide both sides by 2 )

x = 49

Answer:

There are 327,811 doctors.

Step-by-step explanation:

Percentage of female doctors = $16.9$ %

Number of female doctors = $55,400$

Percentage of Male doctors = $100-16.9$ %

= $83.1$ %

So if $55,400$ doctors are represented by $16.9$ how many doctors are represented by $100$ %?

$100$ % represents total number of doctors.

⇒ $\frac{55,400}{16.9} \times100$

=327,810.65

Number of doctors has to be a whole number so we rounf off the number to nearest whole number:

Therefore there are 327,811 doctors.

Answer:

Tamara's example is in fact an example that represents a linear functional relationship.

This is because the cost of baby-sitting is linearly related to the amount of hours the nany spend with the child: the more hours the nany spends with the child, the higher the cost of baby-sitting, and this relation is constant: for every extra hour the cost increases at a constant rate of $6.5.

If we want to represent the total cost of baby-sitting in a graph, taking the variable "y" as the total cost of baby-sitting and the variable "x" as the amount of hours the nany remains with the baby, y=5+6.5x (see the graph attached).
The relation is linear because the cost increases proportionally with the amount of hours ($6.5 per hour).
See table attached, were you can see the increses in total cost of baby sitting (y) when the amount of hours (x) increases.
