Since beth was born, the population of her town has increased at a rate of 850 people per year. on beth 9ths birthday, the total population was nearly 307,650.write and solve a linear equation on beths 16th birthday.

Equation: x = 850y + 300,000

population on beth's 16th birthday: x= 313, 600

Step-by-step explanation:

If "x" is the population when beth has "y", then

x = 307,650 + 850(y-9)

The population in y years is 307,650 plus the number of years that has pased since she had 9 year: (y-9) multiplied by 850 wich is how much the population increases  in a year.

We can simplify the problem eliminating the parenthesis:

x = 307,650 + 850y - 850*9

x = 850y + 300,000

Thus, for the 16th birthday

y= 16

x = 850(16) + 300,000

x= 313, 600

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq
