Answer (quite straightforward):
650
= 65 x 10
Answer:
Step-by-step explanation:
- 1/a + 1/b =
- b / ab + a / ab =
- (b + a) / ab
The common denominator is ab
Correct choice is D
Answer:
the mean is the sum of them all divided by the number of terms.
mean: 13
the mode is the element that occurs MOST in the data set.
mode: none
the median is the middle value of all of the numbers.
median: 9
Answer:
The required equation of the line is:

Step-by-step explanation:
Given the equation

comparing the equation with the slope-intercept form

Here,
so the slope of the line is -4.
As we know that the slope of the perpendicular line is basically the negative reciprocal of the slope of the line, so
The slope of the perpendicular line will be: 1/4
Therefore, the point-slope form of the equation of the perpendicular line that also intersects the point (8, 1) is:


add 1 to both sides


Answer:
30
Step-by-step explanation:
Angles on a straight line are equal to 180°
180°-120°= 60°
Sum of Co interior angles are equal to 180°
180°-60° =120°
90°+60°+ x = 180°
((180° - 90° - 60°= 30°))
