Answer:

5π m

Step-by-step explanation:

Using the pythagorean theorem we can figure out that the third side is 5m

A^2 + B^2 = C^2

3^2 + 4^2 = C^2

9 + 16 = C^2

25 = C^2

√23 = √(C^2)

C = 5m

Side C is also the diameter of the circle, so the radius is 5/2, or 2.5

From that we can use the circumference formula, Circumference = 2π<em>r</em>

Circumference = 2 π (2.5) = <u>5π m</u>

Jace is a songwriter who collects royalties in his songs whenever they are played in a commercial or a movie. Jace will earn $50

VashaNatasha [74]

Jace's song were played on 8 commercials and 2 movies

<h3>Further explanation</h3>

Simultaneous Linear Equations could be solved by using several methods such as :

<em>Elimination Method</em>
<em>Substitution Method</em>
<em>Graph Method</em>

If we have two linear equations with 2 variables x and y , then we need to find the value of x and y that satisfying the two equations simultaneously.

Let us tackle the problem!

<em>Number of Commercials = C</em>

<em>Number of Movies = M</em>

$\texttt{ }$

<em>Jaces songs were played on 6 more commercials than movies.</em>

$\boxed{C = 6 + M}$ → <em>Equation 1</em>

$\texttt{ }$

<em>Jace will earn $50 every time one of his songs is played in a commercial and he will earn $140 every time one of his songs is played in a movie.</em>

<em>His total earnings in the royalties from all commercials and movies was $680.</em>

$\boxed{50C + 140M = 680}$ → <em>Equation 2</em>

$\texttt{ }$

<em>Equation 1 ↔ Equation 2 :</em>

$50C + 140M = 680$

$50 ( 6 + M ) + 140M = 680$

$300 + 50M + 140M = 680$

$190M = 680 - 300$

$190M = 380$

$M = 380 \div 190$

$M = 2$

$\texttt{ }$

$C = 6 + M$

$C = 6 + 2$

$C = 8$

$\texttt{ }$

<h2>Conclusion:</h2>

The number of commercials and the number of movies in which Jaces songs where played is respectively 8 and 2

$\texttt{ }$

almond37 [142]

Answer:

Option D, $x > 6$

Step-by-step explanation:

<u>Step 1: Subtract 8 from both sides </u>

<u /> $x + 8 > 14$

$x + 8 - 8 > 14 - 8$

$x > 6$

Answer: Option D, $x > 6$

2x-8y=-24<br> 6x+4y=68<br> Using elimination method

nikklg [1K]

6(2x-8y=-24)
-2 (6x+4y=68)
12x-48y=-144
-12x-8y=-136
-56y=-280

-280÷-56=5
y=5

2x-8 (5)=-24
2x-40=-24
+40. +40
2x=16
16÷2=8
×=8

y=5
x=8
hope this helps, if needed a picture for better understanding,please comment.
