Is 2/13 a repeating decimal

1 answer:

8 0

The denominator 13 cannot be factored so that only 2's and 5's show up, so this means that 2/13 is a non-terminating decimal. Therefore, this decimal repeats itself

Use a calculator to see that: 2/13 = 0.153846 153846 153846 ....

The spaces are put in to help make the number more readable. Note how the "153846" keeps repeating forever

Solve this system of equation using substitution y=2x-4 x+2y=10

Vladimir79 [104]

Y=2x-4
X+2y=10

Put y into the x equation
X+2(2x-4) =10

Expand and simplify
X+4x-8=10
5x-8 =10
5x=10+8
5x=18
X=18/5

Insert x into the original equation to get y
Y=2x-4
Y=2(18/5)-4
Y=16/5
