2x/3 + 5 = 11x/15 + 14

oksano4ka [1.4K]

Step-by-step explanation:

Given:

$\frac{2x}{3} + 5 = \frac{11x}{15} + 14$

Multiply both sides of the equation by the common denominator :

$\frac{2x \times 15}{3} + 5 \times 15 = \frac{11x \times 15}{15} + 14 \times 15$

After doing maximum cancellations,

$= > 10x + 5 \times 15 = 11x + 14 \times 15$

$= > 10x + 75 = 11x + 210$

$= > 10x - 11x = 210 - 75$

$= > - x = 135$

$= > x = - 135$

Hence, value of x is -135

Is (-3, 2) a solution of -4r - 10y< - 9?

Blizzard [7]

Answer:

The point (-3,2) is not a solution of the inequality

Step-by-step explanation:

Inequality

Inequalities relate the left and the right side of an expression with an operator other than the equal sign.

The inequality given in the question is

$-4r - 10y< - 9$

There are many combinations of r and y that make inequality be true. For example, for r=1 and y=1

$-4(1) - 10(1)< - 9$

$-14< - 9$

This relation is true since -14 is less than -9.

Also, there are many combinations that make the given inequality be false.

For example, for r=2 and y=-1

$-4(2) - 10(-1)< - 9$

$-8+10$

$2$

This inequality is false.

Let's test the point (-3,2)

$-4(-3) - 10(2)< - 9$

$12-10$

$2$

Which is false, thus the point (-3,2) is not a solution of the inequality
