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>Let:</em>
<em>Number of Commercials = C</em>
<em>Number of Movies = M</em>
<em>Jaces songs were played on 6 more commercials than movies.</em>
→ <em>Equation 1</em>
<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>
→ <em>Equation 2</em>
<em>Equation 1 ↔ Equation 2 :</em>
The number of commercials and the number of movies in which Jaces songs where played is respectively 8 and 2

Answer:
"To the nearest year, it would be about 9 years"
Step-by-step explanation:
11c)
This is compound growth problem. It goes by the formula:
Where
F is the future amount
P is the present (initial) amount
r is the rate of growth, in decimal
t is the time in years
Given,
P = 20,000
r = 8% = 8/100 = 0.08
F = double of initial amount = 2 * 20,000 = 40,000
We need to find t:
To solve exponentials, we can take Natural Log (Ln) of both sides:
Using the rule shown below we can simplify and solve:
We can write:
To the nearest year, that would be about 9 years
