Let <em>x</em> = 3.191919…. Then 100<em>x</em> = 319.191919…, and we have
100<em>x</em> - <em>x</em> = 319.191919… - 3.191919…
99<em>x</em> = 316
<em>x</em> = 316/99
Next, we have
316 = 297 + 19 = 3 × 99 + 19
so
316/99 = (3 × 99 + 19)/99 = 3 + 19/99
Answer:
0.1
Step-by-step explanation:
0.1
I just put it into a calculator
To find out if a number is prime or composite, divide the number by 2. If it gives no remainder, it is a composite number. Otherwise, it's a prime number.
83 / 2 = 41 R 1
It has a remainder, so it's a prime number.
Answer:
x = -16
Step-by-step explanation:
2/3 x + 1 = 1/6 x -7
Multiply both sides of the equation by 6 to eliminate the fraction
6*(2/3 x + 1) =6( 1/6 x -7)
4x +6 = x -42
Subtract x from each side
4x-x +6 = -42
3x +6= - 42
Subtract 6 from each side
3x+6-6 = -42-6
3x = -48
3x/3 = -48/3
x = -16
