______
Answer:
x=4
___________________
Step-by-step explanation:
-Solving:
2x + 5 – 3 (2x - 7) = 2 (3x – 5) – 4
2x + 5 – 6x + 21 = 6x – 10 – 4
-4x + 26 = 6x - 14
10x= 26+14
10x=40
x=4
-Checking:
x=4
2(4) + 5 – 3 (2(4) - 7) = 8+5-3(8-7) = 13-3(1) =13-3=10
2 (3(4) – 5) – 4 = 2(12-5)-4 = 2(7)-4=14-4=10.

P(at least 5 rolls until 1) = P(4 rolls are not 1) = 5/6 x 5/6 x 5/6 x 5/6 = 0.4823 (4sf)
Fewer than 7 rolls to get second 1 after first takes 3 rolls means second occurs on 4th, 5th or 6th roll
The probability of each of these is 1/6, 5/6 x 1/6 and 5/6 x 5/6 x 1/6 respectively.
P(second 1 on 4th, 5th or 6th roll) = 1/6 + 5/36 + 25/216 = 91/216 = 0.4213 (4sf)
Answer:
X= -1

Answer:
The right solution is:
(a) $1,940
(b) $2,813
Step-by-step explanation:
Given:
Invoice amount
= $8,400
Discount 1
= 33.33%
Discount 2
= 12.5%
So,
The net payable amount will be:
= ![8400\times [1 - \frac{100}{300} ]\times [1 - \frac{12.5}{100} ]](https://tex.z-dn.net/?f=8400%5Ctimes%20%20%5B1%20-%20%5Cfrac%7B100%7D%7B300%7D%20%5D%5Ctimes%20%5B1%20-%20%5Cfrac%7B12.5%7D%7B100%7D%20%5D)
= 
=
($)
Now,
(a)
Amount paid will be:
= 
=
($)
Balance still to be paid will be:
= 
=
($)
(b)
Amount paid will be:
= 
= 
=
($)
Balance still to be paid will be:
=
($)
Thus the above solution is the appropriate one.
