Answer:(E). 25:2
Step-by-step explanation:
First ratio:
Us : India is 5 : 2
Second ratio
India : British is 5 : 1
multiply(5:2) by 5 and multiply (5:1) by 2 to balance the India stamps.
Therefore now
Us : India is 25 : 10
India : British is 10 : 2
The ratio of us : British is 25:2
So, we'll say Mia gets $4.50 a day, since a standard weekend is two days, therefore adding up to $9 a weekend. So if Mia were to do her chores for 4 weekends, she'd have a total of $36 but not $40. So if she were to work an extra weekend, so 5 weekends, she'd have a total of $45. So you can say 5 weekends in order to earn more than $40.

to see what you can take out of the radical, you can always do a quick "prime factoring" of the values, that way you can break it in factors to see who is what.
Step-by-step explanation:
-1/3 a + 4 ≤ 0
3*(-1/3a) + 4*3 ≤ 0*3
-a + 12 ≤ 0
12 ≤ a
12 ⩾a
a⩾12
