Use the simple interest formula to determine the missing value.
1 = $1944, P = $8100, r=4%, t = ?

t=6

Step-by-step explanation:

Simple Interest(I) = $1944

Principal Amount(P) = $8100

Rate(r) = 4%

We need to calculate the value of Time(t).

Simple Interest(I) =

Substituting the values:

So the required time period is 6 years.

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
