2 times the sum of a number and 8 is equal to the difference of 10 and that number find the number

1 answer:

7 0

The equation would look like this
2 (x + 8) = 10 - x
First you distribute: 2x +16 = 10 - x
Next you isolate the variable by adding x to each side and subtracting 16 from each side: 3x = 10 - 16
Simplify: 3x = -6
Divide both sides by 3: x = -2

What is 1/8 divided by 2

slavikrds [6]

When dividing 1/8 by 2
we have to first take the reciprocal of 2
reciprocal is when the numerator and denominator are exchanged
2 when written as a fraction is $\frac{2}{1}$
we need to find the reciprocal of $\frac{2}{1}$ which is $\frac{1}{2}$
then
$\frac{1}{2} of \frac{1}{8}$
when 'of' function is used it means to multiply the 2 fractions
when multiplying fractions multiply the numerators by numerators and multiply denominators by denominators
is $\frac{1}{2} * \frac{1}{8} = \frac{1}{16}$
answer is $\frac{1}{16}$
