netineya [11]

It says that the buildings together are 200 meters high and from the top pf the first to bottom of the second is 20(whole building) but from the top of the first to second is 10 (half of the building ) so if the degree if half the high will be half too so the high will be 200/2 = 100 meters high for each buildings :))

The commutative property of addition means the order of the addends doesn't matter; we get the same sum. In symbols

$a+b = b+a$

<span>11 + 7 = 7 + 11, choice B, is a good illustration of commutativity.

The next part asks us to use the commutative property. Looking at the choices, we see it's not the commutative property of addition we're to use, it's the commutative property of multiplication. Let's write that generally first:

</span> $ab = ba$

Applying that, <span>(4 + 7) * 3 = 3*(4+7), again choice B.
</span>

Solve the linear equation x+3+x-8+x=55

babymother [125]

Answer:

X= 20

Step-by-step explanation:

X+X+X+3-8 = 55 (Place Like terms together)

3x - 5 = 55 (Simplifying Like terms by adding and subtracting)

3x = 55+5 ( Move -5 towards Right hand side of equal as there is 55 which is like term of -5 and if we move any number or value from one side of equal towards other the sign of that value would change)

3x = 60

X= 60/3 ( Move 3 toward others side as there is like term of 3 which is 60 but as on Left hand side of equal sign 3 is multiplying with "X" so when we move any number or value toward other side the operation or sign of that value or number would be change, Multiply change into Divide and vice versa and Add change into subtraction and vice versa)

X= 20
