(9r-18)/2 < 45
9r-18< 90
9r< 108

R=12 because in order to get rid of the 2 in the denominator you have to multiply both sides by 2. Then the equation reads 9r-18<90. Next add the 18 to her 9r<108. And lastly divide by 9 to solve for r. Which in this case is 12

Solve for x ~<br><br><img src="https://tex.z-dn.net/?f=%5Cbold%5Cpink%7Bx%20%7B%7D%5E%7B2%7D%20%2B%205x%20-%206%20%3D%200%7D" id
Troyanec [42]

\qquad \qquad \rm \large \dag  \: Answer  \: \dag

We have been given a Quadratic equation, where we have to find the real values of x ~

So, let's proceed with middle term splitting method :

\qquad \sf  \dashrightarrow \:  {x}^{2}  + 5x - 6 = 0

\qquad \sf  \dashrightarrow \:  x {}^{2}  + 6x - x - 6 = 0

\qquad \sf  \dashrightarrow \:  {x(}^{} x + 6) - 1(x + 6) = 0

\qquad \sf  \dashrightarrow \: (x + 6)(x - 1) = 0

Now, we have two conditions here~

Either (x + 6) = 0

\qquad \sf  \dashrightarrow \: x =  - 6

or (x - 1) = 0

\qquad \sf  \dashrightarrow \: x = 1

On a piece of paper, use a protractor to construct a triangle with angle measures of 100° and 30°.
yanalaym [24]

The third angle measures 50° and all sides have different lengths.

<h3>What is a triangle?</h3>

A triangle is a polygon with three sides and three angles. Types of triangles are<em> isosceles, equilateral, scalene and right angled.</em>

The sum of angles in a triangle is 180 degrees.

A triangle with angle measures of 100° and 30°, let x represent the third angle, hence:

x + 100 + 30 = 180° (sum of angles in a triangle)

x = 50°

Also, all sides have different lengths since all the angles are different.
