Let the sister be x years old.
Then Jessica is x + 5 years old.
Their ages add to 47.
x + x + 5 = 47
2x + 5 = 47
2x = 42
x = 21
x + 5 = 26
Jessica is 26, and her sister is 21.
Based on the equation given, it can be deduced that the value of the number will be 36.
Let the number be represented by x
Therefore, seven less than one-fourth of a number will be:
=(1/4 × x) - 7
= 0.25x - 7
Now, seven less than one-fourth of a number is 2 will be written as:
0.25x - 7 = 2
0.25x = 2 + 7
0.25x = 9
x = 9/0.25
x = 36

Step-by-step explanation:
Answer:
37 years.
Step-by-step explanation:
Interest = PRT/100 where P = Initial Amount, R = rate, T = the time.
So we have the equation:-
8600 + 8600*3.95 * T / 100 = 21000
8600 + 33970T / 100 = 21,000
8600 + 339.7T = 21000
339.7T = 21000 - 8600
T = (21000 - 8600) / 339.7
T = 36.5 years
