If you would like to know what is true about the solution of the set of equations, you can calculate this using the following steps:
2x + 2y = 18
x + y = 9 /*2
______________
<span>2x + 2y = 18
</span>2x + 2y = 18
______________
2x + 2y = <span>2x + 2y
</span>18 = 18
0 = 0
The correct result
would be infinitely many solutions.
Answer:
y=1/3x_1/5=1/3×15=5_1/5×15=3. 5_3=2
Answer:
see the explanation
Step-by-step explanation:
we have
0.888...
This is a <u>repeating decimal</u> (Is a decimal that has a digit, or a block of digits, that repeat over and over and over again without ever ending)
Convert to fraction number
Let
x=0.888...
10x=8.888...
Subtract 0.888... from 8.888... to remove the decimal
10x-x=8.888...-0.888...
9x=8
Solve for x
x=8/9
therefore
Mike fraction is incorrect
because 4/5=0.8
0.8 is a <u>terminating decimal </u>(It's a decimal with a finite number of digits)
Mike's mistake was considering the number as a terminating decimal instead of a repeating decimal
Beth is correct
because
If you divide 8/9
the result is 0.8888888...
<u>27 = 6x + 4y </u>= 1 7/20 = 3 4/5<u>
</u>20 = 2x + 5y<u>
</u>
