To solve, you have to find the perimeter of the board since you are decorating it. The formula for that is
P = (L x 2) + (W x 2)
P = (10 x 2) + (6 x 2)
P = 20 + 12
Perimeter = 32 ft.
Sydney needs 32 ft. of ribbon to border the board.

Display board measurements = 10ft by 6ft
So all the sides would be 10ft, 10ft, 6ft, 6ft
Add them all together= 32ft
Ribbon length would need to be 32ft long

Which of the following statements shows the inverse property of addition?

Olin [163]

Answer:

Statements y + (-y) = 0 shows the inverse property of addition ⇒ 1st answer

Step-by-step explanation:

Let us revise some important notes

The purpose of the inverse property of addition is to get a result of zero (any number added to its opposite will equal zero)
The purpose of the inverse property of multiplication is to get a result of 1 (any number multiplied by its reciprocal will equal 1)
The additive identity is zero
The multiplicative identity is 1
The difference between the additive identity and the inverse property of addition that additive identity states that a number plus zero equals that number, and the inverse property states that the sum of a number and its additive Inverse is zero

In → y + (-y) = 0

∵ -y is the additive inverse of y

∵ The sum of y and its additive inverse = 0

- By using the definition of the inverse property of addition up

∴ Statements y + (-y) = 0 shows the inverse property of addition

the sum of two numbers is -14. If you subtract the smaller number from. the larger number the total is 12. what are the two numb

lara31 [8.8K]

------------------------------------------------------------
Define the two numbers
------------------------------------------------------------
Let one number be x and the other be y

------------------------------------------------------------
Form equations and solve
------------------------------------------------------------
x + y = -14 --------------- (1)
y - x = 12 ------------------(2)

------------------------------------------------------------
(1) + (2)
------------------------------------------------------------
2y = -2
y = -1

------------------------------------------------------------
Substitute y = -1 into (2)
------------------------------------------------------------
y - x = 12
-1 - x = 12
x = -1 -12
x = -13

------------------------------------------------------------
Answer: x = -13, y = -1

How can i solve the following 2(x + 3) = x - 4

julsineya [31]

Answer:

x=-10

Step-by-step explanation:

2(x+3)=x-4

2*x+2*3=x-4

2x+6=x-4

2x-x=-4-6

x=-10
