I think the answer is the first one
Lawns = L
Money he gets from mowing = M
M - $7 - (L * $1.50) = P for 1 Week
Hope this helped :D
Let the distance of the first part of the race be x, and that of the second part, 15 - x, thenx/8 + (15 - x)/20 = 1.1255x + 2(15 - x) = 40 x 1.1255x + 30 - 2x = 453x = 45 - 30 = 15x = 15/3 = 5
Therefore, the distance of the first part of the race is 5 miles and the time is 5/8 = 0.625 hours or 37.5 minutesThe distance of the second part of the race is 15 - 5 = 10 miles and the time is 1.125 - 0.625 = 0.5 hours or 30 minutes.
Answer: Justin: 21 dollars, Raina: 16 dollars, Cho: 42 dollars.
Step-by-step explanation:
Let's say that Justin has x dollars.
Since Raina has 5 dollars less than Justin, Raina has (x - 5) dollars.
Since Cho has 2 times of what Justin has, Cho has 2x dollars.
In total, they have 79 dollars. So by adding up our quantities, they will equal 79 dollars.
x + (x - 5) + 2x = 79
So: 4x - 5 = 79
So 4x = 84
So x = 21
Therefore Justin has 21 dollars
Since Raina has 5 dollars less than Justin, Raina has 16 dollars
Since Cho has 2 times of Justin, Cho has 42 dollars
