Which sentence illustrates the commutative property of addition?

1 answer:

4 0

The answer is: x+y+z= y+x+z. When using commutative property, the sum cannot be changed. Let's plug in our own numbers.

7+8+9=24 so 8+7+9 also equals 24. commutative property is just switching the order that the numbers appear in but in the end, still equals the same thing

How do you solve this equation? step by step... -9(x-9)=252

katovenus [111]

Well think about it this way -9 times what equals 252 you already know x is going to be a negative number because the outcome is positive so try doing the problem backwards 252/-9=-28 so x=-28

Answer:

(3)

Step-by-step explanation:

the sum of n and 5 is (n + 5), then multiply by 3 gives

3(n + 5)

The result is at least 17 which means it must be greater than or equal to 17

3(n + 5) ≥ 17

Definitions given.

The pitch of the roof is given by the ratio of the rise to the run of the roof, which is the slope of the rafter

$The \ pitch \ of \ the \ roof \ is \ \mathbf {\dfrac{6}{13}}$

Please find attached the simple diagram of the house with all measurements labeled

The reason the above value for the pitch and the diagram are correct are as follows:

The given parameters are;

Width of the section of the house on which the gable of the roof is to be placed = 50 feet

Length of the over hang on the sides of the roof = 1 foot each

Total span of the roof = 52 feet

Horizontal length of each rafter, the run = 26 feet

The height of the ridge above the top of the frame, the rise = 12 feet

Required:

To find the pitch of the roof

To draw a diagram of the house showing measurements

Solution:

$Pitch = \dfrac{Rise}{Run}$

$Pitch \ (slope) \ of \ roof = \dfrac{12}{26} =\dfrac{6}{13}$

Please find attached the diagram of the house showing the measurements for the roof parameters and the section of the house where the gable roof is to be placed
