When you have

4x=\dfrac{2}{5}

you can solve the equation by multiplying both sides by 1/4. Then simplify.

4x\cdot\dfrac{1}{4}=\dfrac{2}{5}\cdot\dfrac{1}{4}\\\\x\cdot\dfrac{4}{4}=\dfrac{2\cdot 1}{5\cdot 4}\\\\x=\dfrac{2}{20}=\dfrac{1}{10}

Ulleksa [173]

Answer:

-\frac{13\sqrt{x} }{x}

Step-by-step explanation:

We have been given the following expression;

-13/√x

In order to rationalize the denominator, we multiply the numerator and the denominator by √x;

-\frac{13}{\sqrt{x}}=-\frac{13\sqrt{x} }{\sqrt{x}\sqrt{x}}\\ \\-\frac{13\sqrt{x} }{\sqrt{x^{2} } }\\\\-\frac{13\sqrt{x} }{x}

In triangle​ ABC, the size of angle B is 3 times the size of angle​ A, and the size of angle C is 12degrees less than 6 times th
Dahasolnce [82]

Answer:

A=19.2^o\\B=57.6^o\\C=103.2^o

Step-by-step explanation:

we know that

The sum of the interior angles in any triangle must be equal to 180 degrees

so

A+B+C=180 ----> equation a

B=3A ----> equation b

C=6A-12 ----> equation c

Solve the system by substitution

Substitute equation b and equation c in equation a

A+3A+6A-12=180

Solve for A

10A=180+12\\10A=192\\A=19.2^o

Find the measure of angle B

B=3(19.2^o)=57.6^o

Find the measure of angle C

C=6(19.2)^o-12=103.2^o
