Answer:34
Step-by-step explanation:
Weight of Alex:44
Weight of Bob:44*(3/4)
=33
Combined weight of all of them:111
Combined weight of Alex and Bob=44+33=77
Cole's weight=111-77 =34

<em>This is the required equation of Circle </em>
Answer:
1,2,4,8
Step-by-step explanation:
Help with what there is nothing?
The line passing through (3, -1) and (-1, 5) has this slope:
5+1
m = ---------- = -3/2
-1-3
We need to find the y-intercept. To do this, substitute the knowns (-3/2 for m, -1 for y and 3 for x) into the slope-intercept equation:
-1 = (-3/2)(3) + b. Then: -1 = -9/2 + b, and so b = 9/2 - 1 = 7/2.
The desired equation is y = (-3/2)x + 7/2.
