Hello, could you help me with my math exercise? thank you in advance
Natali [406]

Answer:

100(x - 1)

Explanation:

Let's begin writing down everything

(X×(-11)+5)×(-9)+X-55

Now we can multiply

-9(-11X+5)+X-55

99X-45+X-55

And so we get

100X-100

Factorize 100

100(x-1)

4 corners again<br> -9a + 3b - a + 7b - 13 + a - 10<br> Sorry for the questions pls help
eimsori [14]

Answer:−9a+10b−23

Step-by-step explanation:−9a+3b−a+7b−13+a−10

Combine −9a and −a to get −10a.

−10a+3b+7b−13+a−10

Combine 3b and 7b to get 10b.

−10a+10b−13+a−10

Combine −10a and a to get −9a.

−9a+10b−13−10

Subtract 10 from −13 to get −23.

−9a+10b−23

Enter the simplified form of the complex fraction in the box.
Ket [755]

The problem is:

\frac{\frac{3}{x}+\frac{1}{4}}{1+\frac{3}{x}}

We now do L.C.M. of numerator and add, also do L.C.M. of denominator and add together:

\frac{\frac{12+x}{4x}}{\frac{x+3}{x}}

Dividing by a fraction is same as multiplying by its reciprocal, so we have:

\frac{12+x}{4x} * \frac{x}{x+3} \\

x cancels out, so can multiply and write:

\frac{12+x}{4} * \frac{1}{x+3} \\=\frac{12+x}{4x+12}

This is the simplified form.


ANSWER: \frac{12+x}{4x+12}
