Ok, so what we want to do here is first remove the repeating decimal.
x=2.16 repeating
10x=21.6 repeating
100x=216.6 repeating
Subtract 10x=21.6 repeating from 100x=216.6 repeating. This will get rid of the repeating numbers.
100x=216.6 repeating
-10x=21.6 repeating

90x=195
Divide both sides by 90.
x=195/90
Now you can simplify that into 13/6.
Answer:
10 ft.
Step-by-step explanation:
Because the length of AC is equal to AB, the length of AB must be congruent to the length of AC. Therefore, AB is 10 ft.
Hope this helps! Let me know!
Answer:
(50+40x) dollars
Step-by-step explanation:
THe fixed cost is $50 (this includes everything and 6GB of data).
Now, for every GB <em>OVER</em> 6 GB he uses, company charges $40 extra.
So, if he used "x" GB EXTRA, his EXTRA cost will be 40 * x = 40x
Thus, his total cost in the month would be fixed cost PLUS the extra, which would be
50 + 40x dollars
Answer:
the answer is 3xy
Step-by-step explanation:
2x can be combined with -5x and x because they have the same variables, but 3xy has the variable xy so it cannot be combined with the others
Answer:
this is easy. all you have to do is find a common numeral between each number in each ratio. a ratio is in its simplest form when the two numbers have no numeral in common (for example A being 11:12). B and C both could be simplified because 4 and 28 can both be divided by 4 and 7 and 14 in answer C are both divisible by 7. answers D and E, however, are both already simplified like answer A.
