Answer:
A
Step-by-step explanation:
65+80+35=180 All triangles add up to 180
To solve, we add the 4 numbers (including the one unknown) and divide that total by 4, and this equals the desired overall average of 154.
x= score needed on 4th game
(149 + 162 + 152 + x)/4= 154
add in parentheses
(463 + x)/4= 154
multiply both sides by 4; 4 "cancels out" on the left side
463 + x= 616
subtract 463 from both sides
x= 153
ANSWER: 153 is the score needed on the 4th game to reach the desired overall average of 154.
Hope this helps! :)

Answer:
1
Step-by-step explanation:
1) First, place the given equation in slope-intercept form (
format) to find its slope easier. Isolate the y:
So, the equation of the line in slope-intercept form is 
. When an equation is in slope-intercept form, the 
, or the coefficient of the x-term, represents the slope. Thus, the slope for the given line would be -1.
2) Lines that are perpendicular have slopes that are opposite reciprocals of each other. We need to find the opposite reciprocal of -1, then.
To find the opposite reciprocal of a number, write the given number as a fraction first -- making -1 be written as 
-- then switch the sign and flip the numerator and denominator. So, the opposite reciprocal of -1 is 1, and 1 is the slope of the perpendicular line.
