The time taken by Jill and Cheryl to double their money is 12 years and 18 years respectively.
<h3>What is Algebra?</h3>
Algebra is the study of mathematical symbols and the rule involves manipulating these mathematical symbols.
Jill invested $500 in an account with a compound interest rate of 6%.
Cheryl invests $600 in an account with a compound interest rate of 4%.
The number of years each doubles their money. Using the relation of 72.
where r is the interest rate and t be the time
The time for the Jill will be
The time for the Cheryl will be

82/4+20-15
82:4=20.5
20.5+20=40.5
40.5-15=25.5
3x + 1 - 8x +12 =
so 8x - 3x =5x
1 + 12= 13
so answer is 5x+13
Answer:
72
Step-by-step explanation:
<u>Given:</u>
There were 120 people in total.
60% were parents.
<u>To find:</u>
Number of parents attended.
Solution:
1. 60% of 120
It can also be written as:
Simplify
- Divide by common factor (2)
2. 
Multiply
Divide
Therefore, 72 parents attended the game.
You can find that out by first putting two equations in slope-intercept form y=mx+b by solving for y.
3y - x = 2
3y = x+2
y = (1/3)x + 2/3
9y = 3x + 6
y = (3/9)x + 6/9
y = (1/3)x + 2/3
They are the same line as you can see in the final step.
Since the two lines are the same line, (they "coincide") they are coincident.
Coincident means there are an infinite number of solutions, and since they are the same line, there are an infinite number of solutions.
