Answer:
B.
Step-by-step explanation:
If x is a number, then twice a number is 2x. The difference between 17 and 2x is 17-2x.
Common Error:
A. says 17 less than twice a number. Since it is 17 less, it is 2x-17 not 17-2x.
Hope this answer helped! :)
For this case we have the following system of equations:
We multiply the first equation by -4:
We have the following equivalent system of equations:
We add the equations:
We find the value of the variable "x":
Thus, the solution of the system is:

Answer:
I think it's -5x
Step-by-step explanation:
I'm assuming the zero pair is simply adding
It <span> looks like the first thing you have to find is their GCF, ya reckon ?</span>
The factors of 56 are 1, 2, 4, 7, 8, 13, 28, and 56 .
The factors of 64 are 1, 2, 4, 8, 16, 32, and 64 .
The common factors are 1, 2, 4, and 8 .
The greatest one is 8 .
56/8 = 7
64/8 = 8
56 plus 64 = (8 times 7) plus (8 times 8)
<span>56 plus 64 = </span>8 times (7 plus 8)<span> <== that's the answer</span>
Check it out:
<span>56 plus 64 = </span>120
<span>8 times (7 plus 8) = 8 times 15 = </span><span>120</span>
