This looks hard... good luck ! :D
Answer:
Step-by-step explanation:
<u>We need to find the difference in progress:</u>
- 1/3 - 2/8 =
- 1/3 - 1/4 =
- 4/12 - 3/12 =
- 1/12
The first student is 1/12 ahead
<span>The bisector of an angle of a triangle divides the opposite side into segments that are proportional to the adjacent sides </span>⇒
<span>
10/12 = (3x+2)/(5x-0.4)
10(5x-0.4) = 12(3x+2)
50x - 4 = 36x + 24
50x - 36x = 24 + 4
14x = 28
x = 28/14
x = 2
QS = 3x + 2 = 3*2 + 2 = 6 + 2 = 8
SR = 5x - 0.4 = 5*2 - 0.4 = 10 - 0.4 = 9.6
Answer is QS=8, SR=9.6

Answer:
<em>The total change in his account is represented by the integer -5</em>
Step-by-step explanation:
<u>Operations With Integers</u>
We need to perform addition and subtraction to complete the answer to this problem.
Derrick first withdrew $17 from his account. Since the money is coming out from the account, it's considered as negative. Thus this operation is recorded as -$17.
The next day he deposited $12, which is considered as positive. This operation is considered as $12 or +$12.
The net operation or total change in the account is: -$17 + $12.
Subtracting and simplifying: -$17 + $12 = -$5
The total change in his account is represented by the integer -5
10.25 x 4
20.5 x 2
41 x 1
Hope this helps :)
