<h2>Range of x </h2><h3>-\frac{1}{5} and x>6</h3><h3>Step-by-step explanation:</h3>

Given AB = 4x + 5, BC = 3x - 2 and AC 9x -5

The sum of the length of any two sides of a triangle is greater than the length of third side.

Case I

AB + BC > AC

⇔4x +5 +3x -2 > 9x -5

⇔7x + 3 >9x - 5

⇔ 7x -9x > -5 -3

⇔-2x > -8

⇔x <4

Case II

if AB+AC > BC

4x +5 +9x -5> 3x -2

⇔13x >3x -2

⇔ 13x -3x> -2

⇔10x > -2

⇔x >-\frac{1}{5}

Case III

AC+BC > AB

⇔9x - 5 +3x - 2 > 4x +5

⇔6x -7 > 4x +5

⇔6x -4x >5+7

⇔2x > 12

⇔x > 6

A weather forecaster says the temperature will be about-5C “give or take” 10 degrees. What is the greatest possible temperature?
IRINA_888 [86]

The greatest possible temperature is 5^{\circ} \mathrm{C} and least possible temperature is -15^{\circ} \mathrm{C}

<u>Solution:</u>

Given that according to weather forecaster the temperature will be about -5 degree celsius given or take 10 degree”

Need to determine greatest possible temperature and least possible temperature.

Give and take in given statement means a temperature can go up by 10 degrees and can go down by 10 degrees

So greatest possible temperature will be -5^{\circ} \mathrm{C}+10^{\circ} \mathrm{C}=5^{\circ} \mathrm{C}

Least possible temperature will be -5^{\circ} \mathrm{C}-10^{\circ} \mathrm{C}=-15^{\circ} \mathrm{C}

Hence according to weather forecaster, greatest possible temperature = 5^{\circ} \mathrm{C} and least possible temperature = -15^{\circ} \mathrm{C}

a machinist can produce 114 parts in 6 minutes. at this rate, how many parts can the machinist produce in 15 minutes ​
Lynna [10]

Answer:

285!

Step-by-step explanation:

First you have to find out how may parts are produced in a single minute.

We know that 114 parts are produced in 6 minutes so to find how may parts are made in one minute divide 114 by 6 and get an answer of 19

114÷6=19

Now to find how may parts are produced in 15 minutes multiply 19 (number of parts produdced in one minute) by 15 and get an answer of 285!

19×15=285

Hope this helped! :)
