What is the midpoint between (4,12) and (8,2)

The distance between the x values is 4 and the distance between the y values is 10...

divide the distance between the x values and the y values
add 2 to the 4 on x
add 5 to the 2 on y

gives us the midway point of (4, 7)

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.
