Answer:
1st, 2nd and 6th options
Step-by-step explanation:
Given
- x +
= 6x ( multiply through by 6 to clear the fractions )
4 - 6x + 1 = 36x ← option 1 will have the same solution set
----------------------------------------------------------------------
Adding the 2 fractions on the left side gives
+
- x = 6x , that is
- x = 6x ← option 2 will have the same solution set
------------------------------------------------------------------------
From
4 - 6x + 1 = 36x ( add 6x to both sides )
5 = 42x ← option 6 will have the same solution set
Part A number of combinations of 8 from 10 = 10C8 = 10C2
= 10*9 / 2 = 45
Part B Number combinations = 10C4 = (10*9*8*7)/ (4*3*2) = 210
Total number of ways = 45 * 210 = 9450 (answer)
45 because 1-4 round down and 6-9 round up to make the 44 become a 50
exponents could be any number between 1 and 10
