6x-4bracket(2x-5)>8 or 5x+9<2x-21

Yuri [45]

The solutions to the given inequalities are x < 6 OR x < -10

<h3>Linear Inequalities </h3>

From the question, we are to solve the given inequalities

The given inequalities are

6x - 4(2x - 5) > 8 or 5x + 9 < 2x - 21

First solve,

6x - 4(2x - 5) > 8

Clear the bracket

6x -8x + 20 > 8

6x - 8x > 8 - 20

-2x > -12

Divide both sides by -2 and flip the sign,

That is,

-2x/-2 > -12/-2

x < 6

For,

5x + 9 < 2x - 21

Subtract 2x from both sides

5x - 2x + 9 < 2x - 2x -21

3x < -21 -9

3x < -30

Divide both sides by 3

3x/3 < -30/3

x < -10

Hence, the solutions to the given inequalities are x < 6 OR x < -10

Lela and Pepe are playing a video game. The ratio of Lela’s game score to Pepe's score is 2 : 5. Then Lela completes a quest and

Fed [463]

Answer: Lela's original score was 16.

Step-by-step explanation:

Alright lets get started.

Suppose Lela score was L.

Suppose Pepe score was P.

The ratio of Lela’s game score to Pepe's score is $2:5$

So the equation will be

$\frac{L}{P} = \frac{2}{5}$

Cross multiplying

$5\times L=2\times P$

$P=\frac{5\times L}{2}$ .................equation 1

Then Lela completes a quest and scores 12 bonus points. The new ratio becomes $7:10$

$\frac{L+12}{P} =\frac{7}{10}$

Cross multiplying

$10(L+12)=7P$

Plugging value of P from equation 1

$10(L+12)= 7\times\frac{5L}{2}$

$20L+240=35L$

$15L=240$

$L=16$

Hence the score of Leela originally was 16. Answer
