<span>The total weights must add upto 50 lbs. Let x represents the number of 3 lb weights and y represents the number of 10 lb weights, we frame an equation as 3x + 10 y =50. Because there are some 10 lb weight and some 3 lb weights but we dont know the exact number.</span>

Pls help solve question 3
Lelu [443]

Answer:

If m is the midpoint of ab it means am is equal to mb

am = 3x + 8 and mb = 6x-4

and ab  = am + mb

first find the value of x by using am = mb

3x + 8 = 6x - 4

8 + 4 = 6x - 3x

12 = 3x

x = 4

ab = 3 (4) + 8

= 12 + 8 = 20 = mb

ab = am + mb

= 20 + 20

40

so, the value of ab is 40
