If five times the measure of an angle is decreased by 30, the result is the same as when two times the measure of the angle is i
Serhud [2]

Answer:

  16

Step-by-step explanation:

Let "a" represent the measure of the angle. Then ...

  5a -30 = 2a +18

  3a = 48 . . . . . . . add 30-2a

  a = 16 . . . . . . . . . divide by 3

Tv Is 40 inches in length and 24 inches in width how tall is it
Sedaia [141]

Answer

<em>TV screens are measured on the diagonal  </em>

<em>. In this specific case the TV is shaped like a rectangle , whose diagonal is 40 i n c h e s and its width is 24 i n c h e s : w = </em>

<em>24 i n d = 40 i n  </em>

<em>Then , the sides of the rectangle and its diagonal form a right triangle .  </em>

<em>Therefore , we can determine the height ( l )  </em>

<em>if we can apply the Pythagorean theorem: d 2 = l 2 + w 2  </em>

<em>So , solving for l : l = √ d 2 − w 2  </em>

<em>Thus , substituting: l = √ ( 40 ) 2 − ( 24 ) 2  </em>

<em>Simplifying: d = √ 1024 = 32 i n  </em>

<em>Therefore  </em>

<em>, the height of the TV is:  </em>

<em>32 i n </em>

X:y = 9:7 Form an equation that links x and y
sleet_krkn [62]

Equations are expressions with equal values

The equation that links x and y is 7x = 9y

<h3>How to determine the equation</h3>

The ratio is given as:

x : y = 9 : 7

Express the ratio, as a fraction

\frac xy = \frac 97

Cross multiply

7 *x = 9 * y

Evaluate the product

7x = 9y

Hence, the equation that links x and y is 7x = 9y
