In order to find the percent tip, you divide the amount left by the total amount of the bill:
$5 tip/$20 bill = 0.25
In order to change this into a percent, you need to multiply this 0.25 by 100, so the percent tip left is 25% of the bill
Answer: y = - 40/9
Step-by-step explanation:
3 + 2y / 8 = 1 - y / 5
120 + 10y = 40 - 8y
10y + 8y = 40 - 120
18y = -80
y = -40 /9
Answer:
For the first question, the slope is -3.
For the second question, the point is (-6,7)
Step-by-step explanation:
In point-slope form, to identify the slope, its the number that's before the parenthesis, which in this case, its -3.
In point-slope form, to identify the points, its the number that replaces y1 and x1, which in this case, its -7 and 6. However, in point-slope form, the numbers are the opposite of what they are. For an example, in this equation, -7 is negative, buts its point would actually be positive.

Answer:
Landers' Mean: 136
Landers' Median: 133
Shakaka's Mean: 136
Shakaka's Median: 133
Step-by-step explanation:
Landers:
Least to greatest: 96, 96, 120, 133, 145, 160, 202
Mean: (96+ 96+ 120+ 133+145+ 160+202)/7 = 136
Median: Since the total numbers is odd, it's just flat out in the middle
133
Shakaka:
Least to greatest: 45, 51, 118, 121, 145, 178, 212, 218
Mean: (45+ 51+ 118+ 121+ 145+ 178+ 212+ 218)/8 = 136
Median:
(121 + 145)/2 = 133
