Answer:

12 mountain bikes

Step-by-step explanation:

1200m+800k=30400

m+k=32

k=32-m

Now solving with substitution we get:

1200m+800(32-m)=30400

1200m+25600-800m=30400

400m=4800

m=12

Which is the midpoint of the segment joining (12, 2) and (-5, – 7)?
Rainbow [258]

Answer:

m(x, y)=(\frac{7}{2} , -\frac{5}{2} )

Step-by-step explanation:

Midpoint of line segment is calculated as

m(x, y)=(\frac{x_1+x_2}{2} , \frac{y_1+y_2}{2} )  -----------(1)

Here

(x_1, y_1) = (12,2) \ \  and \ \ (x_2, y_2) = (-5, -7)

Substituting values in equation (1)

m(x, y)=(\frac{12-5}{2} , \frac{2-7}{2} )

m(x, y)=(\frac{7}{2} , -\frac{5}{2} )
