Answer:
no of 5 kg disks is 3, and no of 2 kg disks is (10-3) i.e. 7
Step-by-step explanation:
Let the no of 2kg disks be a.
Let no of 5 kg disks be b.
2a+5b=29
a+b=10
Using substitution, we have
2(10-b) + 5b=29
20-2b+5b=29
20+3b=29
3b=9
b=3
So no of 5 kg disks is 3, and no of 2 kg disks is (10-3) i.e. 7
Answer:
A. y ≥ 2x – 2
Step-by-step explanation:
P = 2a + b + c
Subtract 2a + b on both sides
c = P - (2a+b)
c = P - 2a - b

Answer:
commutative property is C+2+0=C+2
(As a+b=b+a is the law of commutative property of addition )
