He put 3 in the bag because 12 divided by 4 is 3
Seventy three hundreds one thousand two hundred and eighty
The given points are (4,8) & (9,-4)
slope of a line = <u>Y2 - Y1</u>
X2 - X1
====> <u>(-4) - 8</u> = <u>-12</u>
9 - 4 5
40 minutes would be the answer.
120 minutes = 2 hours.
If she rests every 15 minutes, divide 120 by 15 and get 8.
She takes 5 minute rests, so times 5 by the 8, and you get 40.
Hope this helped.
8x+3=13+x
8x-x=13-3 (you put the x on the right to the left side it becomes negative, as well as the 3 on the other side. The goal is to isolate the x's)
7x=10
x=10÷7
x=10/7 or about 1.43
