Answer:

A is the midpoint

Step-by-step explanation:

Given

A(5.2) B(6,-3) and C(4.7)

Required

Which is the midpoint

Midpoint is calculated using:

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

Testing A as the midpoint, we have:

(5,2) = \frac{1}{2}(6+4,-3+7)

(5,2) = \frac{1}{2}(10,4)

(5,2) = (\frac{1}{2}*10,\frac{1}{2}*4)

(5,2) = (5,2)

<em>The above equation is true. Hence, A is the midpoint of B and C</em>

Andrews [41]

Craig has every 13th night and Edie has every 5th night off.

You have to find LCM - the Least Common Multiple that is the smallest ("least") number that both 13 and 5 will divide into.

Since numbers 13 and 5 are both prime, then LCM(13,5)=13·5=65.

This means, they will have the same every 65th night off.

Answer:

Anna  9 and Betty 15

24 ÷ 8 = 3 ← value of 1 part of the ratio , then

3 parts = 3 × 3 = 9

5 parts = 5 × 3 = 15

Anna gets 9 sweets and Betty gets 15
