answer : -90 = -100+x → x = 10

explanation : to solve for x, you are simplifying both sides of the equation, then isolating the variable.

step 1 : move the variable to the left-hand side and change its sign.

ex : -90-x = -100

step 2 : move the constant to the right-hand side and change its sign.

ex : -x = -100+90

step 3 : calculate the sum

ex : -x = -10

step 4 : change the signs on both sides of the equation

ex : x = 10

solution : x=10

hope this helps !

How do you answer this question.

Ipatiy [6.2K]

Lets write this out:-

$\frac{50}{100} + \frac{30}{100}$

To answer this we just need to add the numerators of both fractions because the denominator's are already common multiples.

$\frac{50}{100}+ \frac{30}{100} = \frac{80}{100}$

Now lets simplify $\frac{80}{100}$ .

$\frac{80/20}{100/20}= \frac{4}{5}$

So, $\frac{50}{100}+ \frac{30}{100} = \frac{80}{100}= \frac{4}{5}$

Hope I helped ya!! xD

Is 2/3 greater then1/5

Greeley [361]

Yes, it is. To find this out, you need to make the denominators the same. They can both multiply into 15, so we change the denominators to 15. Whatever we do to the bottom, we also have to do to the top.

2/3 = 10/15

1/5 = 3/15

We can then see that 10 is more than 3 :)
