Let the number of cats be as x

Ratio = 3:5
3:5 = 21 : x
3/5 = 21/x
x= 21 * 5/3
x= 5* 7
= 35 cats..

X - the number of cats

The ratio of dogs to cats is 3:5, and there are 21 dogs.
\frac{21}{x}=\frac{3}{5} \\
3x=21 \times 5 \\
x=7 \times 5 \\
x=35

There are 35 cats in the pet store.

If M (6,8) is the midpoint of line segment AB, and if A has coordinates (2,3) , find the coordinates of B.
sveticcg [70]
Graphing is one way to do the problem.But sometimes, graphing it is hard to do.So here’s an algebraic method.
If M(m1, m2) is the midpoint of two points A(x1, y1) and B(x2, y2),then m1 = (x1 + x2)/2 and m2 = (y1 + y2)/2.In other words, the x-coordinate of the midpointis the average of the x-coordinates of the two points,and the y-coordinate of the midpointis the average of the y-coordinates of the two points.
Let B have coordinates (x2, y2) in our problem.Then we have that 6 = (2 + x2)/2 and 8 = (3 + y2)/2.
Solving for the coordinates gives x2 = 10, y2 = 13
