remember when you the negative to flip the inequality

5x+2 < 12   and 5x+2 >-12  

subtract 2 from each side

5x < 10   and 5x > -14

divide by 5

x<2 and  x > -14/5

-14/5 < x< 2

Answer:

Mr. West estimated a mass to be 265g, but upon carefully measuring it, found the actual mass to be 240g. What was the percent er
spayn [35]

Answer:

<h3>The answer is 10.42 %</h3>

Step-by-step explanation:

The percentage error of a certain measurement can be found by using the formula

P(\%) =  \frac{error}{actual \:  \: number}  \times 100\% \\

From the question

actual mass = 240 g

error = 265 - 240 = 25

So we have

p(\%) =  \frac{25}{240}  \times 100  \\  = 10.41666666...

We have the final answer as

<h3>10.42 %</h3>

Hope this helps you

What radius of a circle is required to inscribe an equilateral triangle with an area of 270.633 cm2 and an altitude of 21.65 cm?
oksano4ka [1.4K]
We know that
 the distance from the centroid of the triangle to one of the vertices is the radius of the circle required to inscribe an equilateral triangle.

[distance centroid of the triangle to one of the vertices]=(2/3)*h
h=the altitude  of the equilateral triangle-----> 21.65 cm
so
[distance centroid of the triangle to one of the vertices]=(2/3)*21.65
[distance centroid of the triangle to one of the vertices]=14.43 cm

the radius is equal to the distance of the centroid of the triangle to one of the vertices
hence
the radius is 14.4 cm

the answer is
the radius is 14.4 cm
