Need help with number 3 inequalities with variables on both sides

Volgvan

Answer:

x ≤ 2

Step-by-step explanation:

We are given the inequality:

$\displaystyle{2x-3 \leq \dfrac{x}{2}}$

First, get rid of the denominator by multiplying both sides by 2:

$\displaystyle{2x\cdot 2-3\cdot 2 \leq \dfrac{x}{2}\cdot 2}\\\\\displaystyle{4x-6 \leq x}$

Add both sides by 6 then subtract both sides by x:

$\displaystyle{4x-6+6 \leq x+6}\\\\\displaystyle{4x \leq x+6}\\\\\displaystyle{4x-x \leq x+6-x}\\\\\displaystyle{4x-x \leq 6}\\\\\displaystyle{3x \leq 6}$

Then divide both sides by 3:

$\displaystyle{\dfrac{3x}{3} \leq \dfrac{6}{3}}\\\\\displaystyle{x \leq 2}$

Therefore, the answer is x ≤ 2

What is the value of d to the nearest tenth?

Ghella [55]

Answer: $d=13.8$

Step-by-step explanation:

A line that cuts a circle at two points is called "secant".

There is a theorem known as "Intersecting Secant Theorem". This is the theorem you need to use to find the value of "d".

According the Intersecting Secant Theorem:

$(14)(14+20)=(16)(16+d)\\(14)(34)=(16)(16+d)$

Having this expression, the next step is to solve for "d":

Use Distributive property:

$476=256+16d$

Subtract 256 from both sides:

$476-256=-256+256+16d$

$220=16d$

Divide both sides by 16:

$\frac{220}{16}=\frac{16d}{16}\\\\13.75=d$

The value of "d" rounded to the nearest tenth is:

$d=13.8$

QUESTION IS DOW BELOW 30 POINTS EACH PLEASE HELP PLEASE HELP PLEASE HELP

Applying the inscribed angle theorem, we have the following measures:

a. Measure of angle RQT = 79°

b. Measure of angle QTS = 51°

<h3>What is the Inscribed Angle Theorem?</h3>

Based on the inscribed angle theorem, the measure of an inscribed angle (i.e. angle RQT and angle QTS) of a circle is half the measure of each of their respective intercepted arcs (arc RQT and arc QRS).

Given the following:

Measure of arc RQT = 202°

Measure of angle QRS = 129°

a. Find the measure of angle RQT:

Measure of angle RQT = 1/2(360 - 202) [inscribed angle theorem]

Measure of angle RQT = 1/2(158)

Measure of angle RQT = 79°

b. Find the measure of angle QTS:

Measure of angle QTS = 1/2(360 - 2(measure of angle QRS)) [inscribed angle theorem]

Measure of angle QTS = 1/2(360 - 2(129))

Measure of angle QTS = 1/2(102)

Measure of angle QTS = 51°

In summary, applying the inscribed angle theorem, we have the following measures:

a. Measure of angle RQT = 79°

b. Measure of angle QTS = 51°

How do i turn 5 into a fraction

Kruka [31]

Here we are supposed to turn 5 into fraction.

as we know the fraction is written in the form of p/q

So we can write

$\\ \ 5=\frac{5}{1}\\ \\ \ p=5, q=1\\ \\$

Hence fraction = $\frac{5}{1}\\$
