A = first number (larger number)
b = second number (smaller number)
a = 8b
a - b = 70 *
* since a is the larger number and their difference is positive, we want a-b.
plug the first equation into the second to get :
a - b = 70
(8b) - b = 70
8b - b = 70
Your correct answer would be choice #2.
2.5 gallons is divided among 10 people.
2.5/10=0.25 gallons
The standard equation for a circle is
(x-h)^2 + (y-k)^2 = r^2
where the center is at (h,k)
For this problem, the center is at (3,2). The abscissa and the ordinate are all positive. So this must be located on the first quadrant.
Hence, the answer is <span>It is located in the first quadrant..</span>
The equation would be y+y1=slope(x+x1) which means it will be y+-21=slope(x+7)
I believe that is right. I don't know what the slope is though. Welp.
A =adults
s= students
so is a/s or a:s
