<u>Answer:</u>

Solve brackets
6(0.66x-3)>8
Multiply 6 with values in the bracket
<em>So, 6x0.66x and 6x-3</em>
4x- 18> 8
Since 4x and 18 are unlike terms, we will take 18 onto the other side, thus:
4x>8+18
4x>26
<em>Now to find the value of x, divide 4 on B.S</em>
x> 
X> 6.5
OR in 'fraction form'
X>
Hope this helps :D
Answer:
1/10
Step-by-step explanation:
The answer is 1/10 because multiply the numerator and got 2 and then the denomi actors and got 20.
So it would be 2/20.
Then you simplify 2/20 to 1/10
2÷2=1
20÷2÷10
Then you get 1/10.

63.75 is the amount of miles 0.85 inches would equal.
A, C, and E. Both sides of the ratio has to change at the same time. If you multiply both sides by 2 you get 8:10. If you divide both sides by 2 you get 2:2.5. and if you divide by 1.5 you get 3:3.75.
Sorry if my explanation doesn't make sense
