How is it an error? Need more explatinion or an example
Jeff received 280$ from his mother
Such questions are the simplest as it needs you to just write the conditions accordingly which then simplifies and provides you the answer.
This question can be solved using two tricks which are shown below:-
Trick 1 :
1 – 1/4 = 3/4 (used for the 1st 7 days)
1/4 – 410 (used for 8th and 9th days)
(3/4)/7 ——- (1/4 – 10)/2
(3/4) x (2/7) = 3/14 ——- (1/4 – 10)
1/4 – 3/14 = (7 – 6)/28 = 1/28 ——- 10
28/28 ——- 10 x 28 =$ 280
Trick 2 :
7 days ——- 3/4
1 day ——- 3/28
2 days ——- 6/28
6/28 ——- (1/4 – 10) = 7/28 – 410
1/28 ——- 10
28/28 ——- 10 x 28 = $280
Thus Jeff received 280$ from his mother.

Answer:
http://www.calcul.com/show/calculator/recurring-decimal-to-fraction?i=0.02...
Step-by-step explanation:
|-5| is equivalent to 5, since that is how far -5 is from 0.
So, the question is simplified to: How far away is -5 from 5?
We get 5-(-5)=10.
Remember, absolute value is always positive (expect for 0) and the distance between two numbers is always positive (expect for 0).
A.<span>(x+3)(x+4)=<span>0
x=-3,-4
B.X=5,4
