We know there are 3 backpacks. So when we add the known values 9 3/4 and 1 3/4, we get 11 1/2. So 32- 11 1/2 will give you the pink backpack weight which is 20 and 1/2 pounds.
Answer:
x=16
Step-by-step explanation:
12 = x - 4
+4 +4
By adding 4 to both sides it cancels out the -4 leaving the x alone and makes x=16
Y= - x + 2 - 4
y = - x - 2
-y = x + 2
-4,6
x^2 - 2x - 24 = 0
Factorise the equation
Products are -6 and 4
(x-6) (x+4) = 0
x = 6 and x = -4
Hope it helped!
