$|2x+3|\geq23\iff2x+3\geq23\ \vee\ 2x+3\leq-23\qquad|\text{subtract 3 from both sides}\\\\2x\geq20\ \vee\ 2x\leq-26\qquad|\text{divide both sides by 2}\\\\x\geq10\ \vee\ x\leq-13$

Which number is greatest? 2.89 times 10 Superscript negative 8 1.997 times 10 Superscript 2 8.9 times 10 Superscript negative 6

love history [14]

<h3> The greatest number is $1.997 \times 10^2$ </h3>

<em><u>Solution:</u></em>

<em><u>Given that the numbers are:</u></em>

$2.89 \times 10^{-8}\\\\1.997 \times 10^2\\\\8.9 \times 10^{-6}\\\\5 \times 10^{-6}$

We have to find the number that is greatest

Convert the numbers to decimal

$2.89 \times 10^{-8} = 2.89 \times \frac{1}{10^8} =0.0000000289$

$1.997 \times 10^2 = 199.7$

$8.9\times 10^{-6}=8.9\times \frac{1}{10^6}=0.0000089$

$5\times 10^{-6}=5\times \frac{1}{10^6}=0.000005$

We can clearly see that, 199.7 is greatest number

Thus the greatest number is $1.997 \times 10^2$

dem82 [27]

Answer:

Step-by-step explanation:

We are given that Hazel has an assortment of red , blue and green balls.

The number of red balls=The number of red balls

The number of green balls is more than the number of blue balls .

Let number of blue balls=x, Number of red balls=y, Number of green balls =z

Let total number of balls=w

Then number of red balls,y= Number of blue balls=x

According to question

x=y

z>x

The total number of balls,w= sum of all balls

$w=x+y+z$

$w=x+x+z$

$w=2x+z$

substitute x<z

$w>2x+x$

$w>3x$

Both side divided by 3 then we get

$\frac{w}{3}>x$

$x$ .

Hazel will have number of blue balls is given by the equation

$x$ .

Where x= Number of blue balls

w=Total number of blue balls.
