First you subtract 8 from 26, which is 18. Then you divide 18 by 6, which is 3. x equals 3.
9y - 5x = 20
or, (9y - 5x) / 20 = 1
or, 9/20 y - 1/4 x = 1
compare with x/a + y/b = 1
you'll get
x intercept (a) = -4
y intercept (b) = 20/9
Answer:

Step-by-step explanation:
Restaurant A <u>served a greater variety of ages</u> than Restaurant B, because the <u>range</u> of data for Restaurant A is greater than that of Restaurant B.
Range of a data set is the data spread.
Restaurant A is serving a greater variety of ages of people since it has a higher range than that of Restaurant B.
83x+P=83x+Q
subtract 83x from each side
P=Q
if P does not Q there are no solutions
the lines would be parallel and never intersect if Q does not equal P
1,100.226 is your answer :)
