60% decimal = .6 fraction= 6/10
3/4 percent =75% (think of $$) decimal =.75
0.23 percent =23% fraction= 23/100
1/8 percent= 12.5 decimal = 0.125
18% decimal= .18 fraction= 18/100 (simplified to 9/50)
2/3 percent=0.6% repeating (so put a line over 6) decimal= 0.6 repeating aswell so do the same as last
Your welcome :)
Solution:
<u>We know that:</u>
- Formula for slope intercept form = y = mx + b (m = slope; b = y-intercept)
- Given equation: y = -2x/5 + 4/5
<u>Compare the equation and the formula:</u>
- y = mx + b and y = -2x/5 + 4/5
<u>This means that:</u>
Hence, the slope of the line is -0.4.
1 hour is 60 minutes
6 hours x 60 = 360 total minutes
Divide total time by number of lessons:
360/8 = 45
Each lesson was 45 minutes
[(18x - 6) / 9x^5] / [(15x + 5) / 21x^2]
<span>The initial equation formulated would be:
[6(3x - 1) / 9x^5][21x^2 / 5(3x + 1)] </span>
By simplifying:
[126x^2(3x - 1) / [45x^5(3x + 1)]
14(3x - 1) / 5x^3(3x + 1)
<span>Therefore, the simplest form would be:
(42x - 14) / (15x^4 + 5x^3)
