Answer:
5,244 ft
Step-by-step explanation:
4,579 ft + 985 ft − 320 ft = 5,244 ft
To find Margos's average at the end of seven months, subtract the average drop in points per month from her initial grade average.
To find Margos's average at the end of seven months, we need to subtract the average drop in points per month from her initial grade average. Since her average dropped by an average of five-eighths of a point per month, we can write this as a rational number expression: 92 - (5/8 * 7). To evaluate this expression, we first multiply 5/8 * 7 = 35/8. Then we subtract this from 92: 92 - 35/8. To subtract these fractions, we need a common denominator: 92/1 - 35/8 = 736/8 - 35/8 = (736 - 35)/8 = 701/8.
So Margos's final average after seven months is 701/8 or 87.625.

Answer:
There were 149 voters over 65 years.
Step-by-step explanation:
In the picture attached, we can see that 25% of the voters were over 65 years.
25% of 596 voters is computed as follows:
total number of voters * desired percentage / 100
596*25/100 = 149

Answer:
slope = -1.5
Step-by-step explanation:
A set of three or more points are said to be collinear if they all lie on the same straight line.
We have been given the following collinear set of points;
P(0, 3), Q(2, 0), R(4, -3)
This implies that P, Q, and R lie on the same line.
The slope of a line is defined as; (change in y)/(change in x)
Using the points P and Q, the slope of the line is calculated as;
(0-3)/(2-0) = -3/2 = -1.5
Answer:
-3/2
