Convert 11.42424242 to a rational expression in the form of a/b , where b ≠ 0.

11.424242
isolate the repeating part
11+0.424242

focus on the repeating part
0.42424242
how many places till it repeats again?
2
let's say it is x
x=0.42424242
multiply by 100
100x=42.424242

subtract them
100x-x=42.42424242-0.42424242
the infinite repeats cancel and we get
99x=42
divide by 99
$x=\frac{42}{99}$

so
$11.\overline{42}=11 \space\ \frac{42}{99}$

17) $x-8=11$

18) $9-x=5$

19) $x+6=7$

20) $x+(-4)=-18$

Step-by-step explanation:

17) The difference between a number and 8 is 11

Let number = x

then the equation will be:

$x-8=11$

Solving:

$x-8=11$

$x=11+8\\x=19$

18) Nine less than a number is five.

Let number = x

then the equation will be:

$9-x=5$

Solving:

$9-x=5\\-x=5-9\\-x=-4\\x=4$

19) Seven is equal to a number plus 6

Let number = x

then the equation will be:

$x+6=7$

Solving:

$x+6=7\\x=7-6\\x=1$

20) The sum of a number and -4 is -18

Let number = x

then the equation will be:

$x+(-4)=-18$

solving:

$x+(-4)=-18\\x-4=-18\\x=-18+4\\x=-14$
