Phoenix [80]

Answer: $\begin{bmatrix}\mathrm{Solution:}\:&\:x\le \:-\frac{2}{3}\quad \mathrm{or}\quad \:x\ge \:0\:\\ \:\mathrm{Decimal:}&\:x\le \:-0.66666\dots \quad \mathrm{or}\quad \:x\ge \:0\\ \:\mathrm{Interval\:Notation:}&\:(-\infty \:,\:-\frac{2}{3}]\cup \:[0,\:\infty \:)\end{bmatrix}$

Step-by-step explanation:

$\left|x-2\right|+\left|2x+1\right|\ge \:3$

$x$

$x\le \:-\frac{2}{3}\quad \mathrm{or}\quad \:0\le \:x$

$x\le \:-\frac{2}{3}\quad \mathrm{or}\quad \:x\ge \:0$

How do you answer this question.

Ipatiy [6.2K]

Lets write this out:-

$\frac{50}{100} + \frac{30}{100}$

To answer this we just need to add the numerators of both fractions because the denominator's are already common multiples.

$\frac{50}{100}+ \frac{30}{100} = \frac{80}{100}$

Now lets simplify $\frac{80}{100}$ .

$\frac{80/20}{100/20}= \frac{4}{5}$

So, $\frac{50}{100}+ \frac{30}{100} = \frac{80}{100}= \frac{4}{5}$

Hope I helped ya!! xD

with Judy jogging north and Jackie jogging west (on straight roads). When Jackie is 1 mile farther fro m the intersection than J

miskamm [114]

Let the distance of Judy from intersection is x and distance of Jackie from intersection is y.

We convert the given information to equations, step by step.

Point 1: When Jackie is 1 mile farther from the intersection than Judy.

This means y is 1 mile more than x.

So,

y = 1 + x

Point 2: The distance between them is 2 miles more than Judy’s distance from the intersection.

Distance between is x+ y.

So, x+y is 2 miles more than y.

x+y = y + 2
⇒
x = 2

From point 1 we have:

y = 1 + x = 1+ 2 = 3

So,

Distance of Judy from intersection is 2 miles and distance of Jackie from intersection is 3 miles.
