Answer:
15 = 0.025
16= 3 years
Step-by-step explanation:
15.
I=prt
15= (200)(r)(3)
200(3) = 600r
15 divided by 600r = 40 (0.025)

t= 3 years
Answer:
D. 
Step-by-step explanation:
The mathematical transcription of the statement is:
Which corresponds with option D.
Solve for the first variable in one of the equations, then substitute the result into the other equation.
Point Form: (-1,0)
Equation form: x=-1,y=0
Carl present age is 10 years while Dennis present age is 19 years.
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more variables and numbers.
Let x represent Carl present age and y represent Dennis present age, hence:
x + y = 29 (1)
Also:
After 6 years:
x + 6 = y - 3 (2)
From both equations:
x = 10, y = 19
Carl present age is 10 years while Dennis present age is 19 years.
