Answer:
Solution of a System. In general, a solution of a system in two variables is an ordered pair that makes BOTH equations true. In other words, it is where the two graphs intersect, what they have in common. So if an ordered pair is a solution to one equation, but not the other, then it is NOT a solution to the system.
Pretty simple: The answer is D
Answer:
t = d/S
Step-by-step explanation:
S = d/t
Cross multiply
S x t = d
Divide both sides by S
S/S x t = d/S
t = d/S
Answer:
9 years
Step-by-step explanation:
Simple interest for any amount p is given by
SI = P*R*T/100
where R is the rate of interest
T is the time period in years
given
P =$1500
R = 4%
T we have to find
SI = $540
Thus, putting the given value in SI = P*R*T/100
540 = 1500*4*T/100
T = 540*100/1500*4 = 9 years
Thus, It will take 9 years for Sam to earn $540
