Answer: x= -4
Step-by-step explanation:
Combine like terms
-4x -7 -3x + 4 = 25
-7x -3 =25
Add 3 on both sides
-7x=28
Divide by -7 on both sides
x= -4
Hope this helps! :)
The pattern here is the number times 3 then plus 1
We can check this by plugging it in.
1×3=3
3+1=4
4 is the next number in our sequence so the pattern works.
We can continue to check this with the rest of our sequence.
4×3=12
12+1=13
13 is the next number in our sequence so the pattern works.
13×3=39
39+1=40
40 is the next number in our sequence so the pattern works.
40×3=120
120+1=121
121 is the next number in our sequence so the pattern works.
We can find the next numbed in the sequence by continuing the patter
121×3=363
363+1=364
So the next number in the sequence is 364
To find the answer:
The probability of getting a ten:
=4/52
The probability of getting a king:
=4/52
The probability of getting a diamond:
=52×1/4
=13/52
However,there would be king and ten of diamond which overlapped and therefore -2/52 would be in the equation.
We can then sum up to find the equation:
=4/52+4/52+13/52-2/52
=21/52-2/52
=19/52
Therefore the answer is 19/52.

<span>The book has sold 442,696 copies to date.
This was calculated by making a proportion: 8.9 : 39,400 = 100 : X where X Is the number of copies sold.
Then I calculated 39,400*100/8.9 to obtain the answer</span>
Start by distributing the - 1/3 which is the same as dividing the entire parentheses by 3 which results in (3x+10)
