Answer:
1. y = 5 - 2x
2. b = a - 3
3. x = 5y - 12
4. c = (12+7d)/3
5. y = (24-4x)/3
6. x = (4 - 3y)/2
Step-by-step explanation:
(21/25) * 100
84 %
82 %
0.8 * 100
80 %
(17/20) * 100
85 %
17/20 is the highest one
6d -11/2 = 2d -13/2
Subtract 2d from both sides
6d -11/2 - 2d = 2d -13/2 - 2d
Simplifying
4d -11/2 = -13/2
Add 11/2 to both sides
4d -11/2 + 11/2 = -13/2 + 11/2
Simplifying
4d = -2/2
4d = -1
Divide both sides by 4
4d/4 = -1/4
Simplifying
d = - 1/4
6/7 (85%) is bigger than 3/4 (75%)
