0.224 is the answer to this question.
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.

Step-by-step explanation:
Combine Like Terms - 2x(3x) = 16
Calculate - 6x² = 16
Divide - x² = 8/3
Simplify - x = ± <u>-2</u>

The unit rate is the slope
y=mx+b
m=slope
b=y intercept
equation is y=7x
slope=7
y intercept=0
slope=unit rate because if you use 5 gasoline then you go 5 times 7 miles or 35 miles
The unit rate is 7
