Answer:
5/12
Step-by-step explanation:
She spent 1/3=4/12 and 1/4=3/12. In total 4/12 + 3/12=7/12. Now subtract 7/12 from the total: 12/12 - 7/12=5/12.
Simplify the following:
7 - 3 (9×2 n + (3 n + 8 n)/(-n))
3 n + 8 n = 11 n:
7 - 3 (9×2 n + (11 n)/(-n))
(11 n)/(-n) = n/n×11/(-1) = 11/(-1):
7 - 3 (9 2 n + 11/(-1))
Multiply numerator and denominator of 11/(-1) by -1:
7 - 3 (9 2 n + -11)
9×2 = 18:
7 - 3 (18 n - 11)
-3 (18 n - 11) = 33 - 54 n:
33 - 54 n + 7
Add like terms. 7 + 33 = 40:
40 - 54 n
Factor 2 out of 40 - 54 n:
Answer: 2 (20 - 27 n)
0.2(6x+1)/3.6=0.5x/9
Solution
(1.2x + 0.2)/3.6 = 0.5x/9
Cross multiplying, we get
9(1.2x + 0.2) = 3.6 * 0.5x
10.8x + 1.8 = 1.8x
10.8x - 1,8x = -1.8
9x = -1.8
Dividing both sides by 9, we get
x = - 0.2
That's the answer.
Thank you.
