Answer:3: If a linear system has the same number of equations and variables, then it must have a unique solution.
Step-by-step explanation:just this which correct
Answer:
The distance from Gary's school to the BART station is 564 yards
Step-by-step explanation:
Let
x ----> the distance from Gary's school to the corner market
y ----> the distance from Gary's school to the BART station
we have
![x=47\ yd](https://tex.z-dn.net/?f=x%3D47%5C%20yd)
we know that
To find out the distance from Gary's school to the BART station, multiply the distance from Gary's school to the corner market by 12
so
![y=12x](https://tex.z-dn.net/?f=y%3D12x)
substitute the value of x
![y=12(47)=564\ yd](https://tex.z-dn.net/?f=y%3D12%2847%29%3D564%5C%20yd)
therefore
The distance from Gary's school to the BART station is 564 yards
2/3 + 1/4 .....common denominator is 12
8/12 + 3/12 =
11/12 <==
ANSWER:
5900$
EXPLICATION:
5000$ represents 100% of the loan
We have to find out how much is a 6% of this loan.
100%—->5000$
6%—->6x100/5000=300$
So he have to pay 300$ per year
So in three years it will be 300x3=900$
We add it to the loan and we got 5900$
