Solve the problem.
The formula [tex]$A=P+P r t$[/tex] represents the value, [tex]$A$[/tex], of an investment of [tex]$P$[/tex] dollars at a yearly simple interest rate, [tex]$r$[/tex], for [tex]$t$[/tex] years. The equation to model the value, [tex]$A$[/tex], of an investment of [tex]$$54$[/tex] at 9.26% for [tex]$t$[/tex] years is given by
[tex]$A=54+5 t$[/tex]
The equation to model the value, [tex]$A$[/tex], of an investment of [tex]$$84$[/tex] at 2.38% for [tex]$t$[/tex] years is given by
[tex]$A=84+2 t .$[/tex]
Assuming [tex]$A$[/tex] has the same value, the given equations form a system of two linear equations. Solve this system using an algebraic approach and interpret your answer.
a. [tex]$t =5$[/tex]
The two investments will reach the same value in 5 years.
b. [tex]$t=20$[/tex]
The two investments will reach the same value in 20 years.
c. [tex]$t =1000$[/tex]
The two investments will reach the same value in 1000 years.
d. [tex]$t=10$[/tex]
The two investments will reach the same value in 10 years.
Answer (3)
2/3 - 6/3 = -4/3 or -1 1/3 (negative one and one third)
0/0 because two thirds are lower then sixth rids unless u switch it then it would be 3/1
The result of two-thirds minus six-thirds is negative four-thirds, represented as − 3 4 . When subtracting fractions with the same denominator, we can simply subtract the numerators. Therefore, the final answer is − 3 4 .
