Given two numbers A and B, the commutative property of addition says:
A+B=B+A
Therefore:
9+8=8+9=17

Answer:
2(8a + 8)
Step-by-step explanation:
The easiest way to do this is to substitute <em>a</em> for a number. For example, let's just make things easy and make <em>a </em> = 1.
So, if a = 1, the expression 16a + 8 would be 16(1) + 8 = 24.
Let's find all the expressions that would also equal 24 if <em>a = </em>24.
Plug in 1 for <em>a</em> in each of the equations. You will find that 2(8a + 8) will not equal 24 if <em>a </em>equals 1.
2(8a + 8)
2(8(1) + 8
2(8 + 8)
2(16)

Answer: 16
You divide 8 by 1/2 and you get 16 pieces
Answer:
$440
Step-by-step explanation:
notes $2 - n
notes $10 - m
n + m = 80 ----------> m = 80 - n
1 - 2/5 = 3/5
45 * $2 + 35 * $10 = 90 + 350 = $440
