How to show my daughter to do this and it needs to be changed to a mix number.
densk [106]

Solution 1 by separating parts

Rewriting our equation with parts separated

−5/6 −2−1/10

Solving the fraction parts

−5/6−1 1/0=?

Find the LCD of 5/6 and 1/10 and rewrite to solve with the equivalent fractions.

LCD = 30

−25/30−3/30= −28/30

Reducing the fraction part, 28/30,

−28/30= −14/15

Combining the whole and fraction parts

−2−14/15= −2 14/15

Solution by Formulas

converting mixed numbers to fractions, our initial equation becomes,

−5/6−21/10

Applying the fractions formula for subtraction,

=(−5×10)−(21×6)6×10

=(−50−126) / 60

= −176 / 60

Simplifying -176/60, the answer is

= −2 14/15

I hopes this helps!!! :)

Here is an interesting exponential function,
Sladkaya [172]

The number 1 raised to any number will always equal 1.

So the Y values in the chart are all 1.

Then the plot would be a straight horizontal line at Y1, so it is neither growth or decay.

What is 24.534 rounded to the nearest hundredth
alina1380 [7]
It's just 24.53 because the hundredth place is the 3, but the value after it is not high enough to round it up. Therefore, the answer is 24.53
