The area of the triangular kite would be 12 feet
Option D. 96 is the correct answer.
Explanation:
Let the higher grade be = x
Let the lower grade be = y
As given, The difference of the two grades is 16
or 
.... (1)
The sum of one-eighth of the higher grade and one-half of the lower grade is 52.
... (2)
Putting the value of x=16+y in equation (2)
As x=16+y
x=16+80 = 96
Hence, higher grade is 96.
Identify the slope, m. This can be done by calculating the slope between two known points of the line using the slope formula.
Find the y-intercept. This can be done by substituting the slope and the coordinates of a point (x, y) on the line in the slope-intercept formula and then solve for b.
Answer:
y= -2
Step-by-step explanation:
Check the solution of all options
First option
p + 2 1/2 = 5
p = 5 - 2 1/2
p = 5 - 5/2
p = 10/2 - 5/2
p = 5/2
p = 2 1/2
Second option
2 + p = 2 1/2
p = 2 1/2 - 2
p = 1/2
Third option
p - 2 1/2 = 5
p = 5 + 2 1/2
p = 7 1/2
Fourth option
4 - p = 2 1/2
-p = 2 1/2 - 4
-p = 5/2 - 4
-p = 5/2 - 8/2
-p = -3/2
p = 3/2
p = 1 1/2
The equation that has p = 2 1/2 as its solution is first option
