If you would like to know how many minutes will it take you to mow a lawn that measures 6000 square feet, you can calculate this using the following steps:
800 square feet ... 15 minutes
6000 square feet ... M minutes = ?
800 * M = 15 * 6000
M = 15 * 6000 / 800
M = 112.5 minutes
This will take 112.5 minutes.
Solve for y:
y + 1 = -3/5x + 2.4 (multiply 4 by 3/5 no negatives because negative times a negative is a positive)
y = -3/5x + 1.4
Now graph the y-intercept of 1.4.
Then plot points using slope.
Hope this helps and let me know if you have more questions!
10+30=40(total number of students in the class)
take this number and divide by 5
40/5=8 (students)
ANSWER: 8 students signed up for the competition
Log(1/216)^(x+2) = log 6^12
(x+2) log(1/216) = log 6^12
xlog(1/216) + 2log(1/216) = log6^12
xlog(1/216) = log6^12 - 2log(1/216)
x = [log6^12-2log(1/216] / log(1/216)
x = -6
