Solve for a and graph the solution on the number line below.

oksian1 [2.3K]

Solve for x and graph the solution on the number line below.

$-x-5 \geq 1 \text { or }-x-5 < -8$

$-x-5 \geq 1$

Add 5 to both sides

$-x-5+5 \geq 1+5$

Simplify

$-x \geq 6$

Multiply both sides by - 1 (reverse the inequality) $(-x)(-1) \leq 6(-1)$

Simplify

$x \leq-6$

$-x-5 < -8$

Add 5 to both sides

$-x-5+5 < -8+5$

Simplify

$-x < -3$

Multiply both sides by $-1$ (reversing the inequality)

$(-x)(-1) > (-3)(-1)$

Simplify

$x > 3$

The idea of inequality, which is the state of not being equal, especially in terms of status, rights, and opportunities, is at the core of social justice theories. However, because it frequently has diverse meanings to different individuals, it is prone to misunderstanding in public discourse. However, certain distinctions are universal.

In mathematics, inequalities specify the connection between two non-equal numbers. Equal does not imply inequality. Typically, we use the "not equal sign (≠)" to indicate that two values are not equal. But several inequalities are utilized to compare the numbers, whether it is less than or higher than.

Can somebody help solve either of these?

Leya [2.2K]

First one:
The circumference of the whole circle is (2π x the radius),
and 60° is (60/360) = 1/6 of the whole circumference.

Second one:
The area of the whole circle is (π x the radius²), and
the 40° sector is (40/360) = 1/9 of the whole area.

I hope this is enough help.

Can anyone help me with this. It asks to solve and check your answer.

tankabanditka [31]

$\sf 4m-21=3(5m-1)$

First, distribute 3 into the parenthesis(multiply it to every term inside):

$\sf 4m-21=15m-3$

Add 21 to both sides:

$\sf 4m=15m+18$

Subtract 15m to both sides:

$\sf -11m=18$

Divide -11 to both sides:

$\sf m=-\dfrac{18}{11}$

To check our work we can plug this back into the original equation for 'm':

$\sf 4m-21=3(5m-1)$

$\sf 4(-\dfrac{18}{11})-21=3(5(-\dfrac{18}{11})-1)$

Multiply:

$\sf -\dfrac{72}{11}-21=3(-\dfrac{90}{11}-1)$

Distribute 3 into the parenthesis:

$\sf -\dfrac{72}{11}-21=-\dfrac{270}{11}-3$

Subtract:

$\sf -\dfrac{303}{11}=-\dfrac{303}{11}~\checkmark$

Both sides are equal to each other, so we solved it correctly.
