Answer:
see below
Step-by-step explanation:
4x + 10 = 2(2x + 5)
Distribute
4x+10 = 4x+10
Since the left side is identical to the right side, there are infinite solutions
4x - 5 = 4x + 10
Subtract 4x from each side
-5 = 10
This is never true, so there are no solutions
4x-5 = -5
Add 5 to each side
4x = 0
x=0
There is one solutions
Brand a: per fork is 0.06 cents.
Brand b: per fork is 0.05
Choose brand B!
The answer would be negative 9. 2*-3 which is -6 and -6-3 would be -9.
<u> 0.87
</u> 99 | 870
-<u>792</u>
780
-<u>693
</u> 87
Since it is now 87 again, the process repeats, yielding 0.87 recurring
