Kamila [148]

Answer:

a. 12 years

b. 30 years

Step-by-step explanation:

a) Assume Liaqat's age is x. His age would be:

5x + 10 = 70

5x = 70- 10

x = (70 - 10) / 5

x = 12

Liaqat is 12 years old.

b. Assume his uncle's age is y;

4y - 10 = 130

4y = 130 - 10

y = (130 - 10) / 4

y = 30

Liaqat's uncle is 30 years old.

3x^2-3x ----------- -3 x^2-9x please give me the simplified answer + explanation

STatiana [176]

You want us to simplify $\frac{3x^2-3x}{x^2-9x}-3$

first, factor top and bottom
$3x^2-3x=3x(x-1)$
$x^2-9x=x(x-9)$

so we have
$\frac{3x(x-1)}{x(x-9)}-3=$
$\frac{3(x-1)}{x-9}-3$
we want to combine fractions so multiply 3 by $\frac{x-9}{x-9}$
$\frac{3(x-1)}{x-9}-\frac{3(x-9)}{x-9}=$
$\frac{3(x-1)-3(x-9)}{x-9}=$
$\frac{3x-3-3x+27}{x-9}=$
$\frac{24}{x-9}$

the simplified answer is $\frac{24}{x-9}$
