What is the value of y?<br> 40°<br> Y + 30°

stepan [7]

Answer:

y = 55

Step-by-step explanation:

The sum of the angles of a triangle are 180

40 + y+30 + y = 180

Combine like terms

70 +2y = 180

Subtract 70 from each side

2y = 180-70

2y = 110

Divide each side by 2

2y/2 = 110/2

y = 55

Divide. Express the quotient in simplest form.<br> x^2−x−12/2x^2÷x^2+x−6/2x^3

sertanlavr [38]

Hey there!

These are technically expressed as fraction. When you divide a fraction by another, you can replace the second fraction with its reciprocal and you can now multiply the fractions together instead.

$\frac{x^2-x-12}{2x^2} / \frac{x^2+x-6}{2x^3}$

$\frac{x^2-x-12}{2x^2} * \frac{2x^3}{x^2+x-6}$

Now, just multiply across the top and the bottom. You can first cancel out any terms that are repeated or similar.

$\frac{12}{2x^2} * \frac{2x^3}{-6}$

$\frac{2}{x} * \frac{1}{-1}$

$\frac{2}{-x}$

Your answer will be $\frac{2}{-x}$ .

Hope this helped you out! :-)
