1. 72% = 18/25, 0.72
2. 25% = 1/4, 0.25
3. 500% = 5 or 5/1
4. 5% = 1/20, 0.05
5. 37% 37/100, 0.37
6. 165% = 1 13/20, 1.65
7. 5/8 = 0.625, 62.5
8. 258/300 = 0.86, 86%
9. 350/100 = 3.5, 350%
10. 12 ÷ 15 = 0.8 = 80%= 8/10
11 68 ÷ 80 = 0.85 = 85% = 17/20
X * 29% = 60.90
60.90/.29 = 210
her paycheck was $210.
The answer is that there is no solution.
The problem would be 16x = 16x so there is no solution.
she walked 1 3/8 miles more than she ran, Hope this helps :D
The third one, this is because you take your y2 and y1 values (y2=0 and y1=9 because these are the two y values given to you from each coordinate) and subtract 0-9. then you do the same, but with the x2 and x1 values. so your x1 value is 3 and your x2 value is 0, so you subtract 0 from 3. divide your second answer from the first answer, to get a gradient of -1/3 x. now using the first coordinate (0,9) you know that the y coordinate is 9. as the x value =0, we know that the line is passing through the y axis at 9 so 9 is your y intercept. this gives you the equation -1/3x+9. hope this helped and wasn't too confusing!
