Write the solution to the inequality in set - builder notation: 5r + 8 < 63

Leni [432]

First, the inequality needs to be solved. The first step is to subtract 8 from both sides of the inequality, leading to 5r < 55. Dividing 5 out from both sides, this will leave r < 11. Next, to form a set notation, the inequality is written in such form: {r | r < 11}.

Can somebody help me with this?

Natasha_Volkova [10]

Step-by-step explanation:

Hey there!

By looking through figure, l and m are parallel lines and a transversal line passes through the lines.

Now,

7x + 12° = 12x - 28°( alternate angles are equal)

12°+28° = 12x - 7x

40° = 5x

$x = \frac{40}{5}$

Therefore, x = 8°

Now,

12x - 28° + 9y - 77 = 180° ( being linear pair)

12×8° - 28° + 9y -77° = 180°

96° - 28° + 9y - 77° = 180°

-9 + 9y = 180°

9y = 180° + 9°

y = 189°/9

Therefore, y = 21°

Therefore, X = 8° and y= 21° .

Hope it helps....

Answer:

x= 0

Step-by-step explanation:

Here in this question, we are given a linear equation of single variable x, and we have to solve the equation for x.

The given equation is 9x -7= -7 ....... (1)

Now, taking all the constant terms to the right side of the equation and all the x terms to the left side of the equation.

Hence, the equation becomes

9x = -7 +7

⇒ 9x =0 {Since, -7 and 7 cancels each other}

⇒ x= 0/9= 0 (Answer) {Since zero divided by any number is equal to zero}
