Answer:
3.6
Step-by-step explanation:
Let x be the number of boys, then,
(3*x*18+x*y)/(3x+x)=17
(54+y)/4=17
y=14 points each boy.
Step-by-step explanation:
soln:
let,
(x1,y1) =(2,4)
(x2,y2)=2,-7)
Now,
By midpoint formula,
×= <u>x</u><u>1</u><u>+</u><u>x</u><u>2</u>
2
= <u>2</u><u>+</u><u>2</u>
2
=<u>4</u>
2
=2,,
And,
Y=<u>y</u><u>1</u><u>+</u><u>y</u><u>2</u>
2
=<u>4</u><u>-</u><u>7</u>
2
= <u>-</u><u>3</u>
2
Hence ,
The mispoint between points (2,4) and (2,-7) is (2,<u>-</u><u>3</u><u> </u><u> </u><u> </u><u>)</u>

I got D for this one................
Answer:
