Answer:

y = 1

x = -1

Step-by-step explanation:

x - 2y = -3, then x = 2y - 3

2x + y = -1

substitute for x:

2(2y - 3) + y = -1

4y - 6 + y = -1

5y = 5

y = 1

x = 2 - 3 = -1

What equation will give the perimeter of the figure? HELP HELP HELP
nata0808 [166]

Answer:

(2l + 2w) + (a + b + c)

Step-by-step explanation:

The formula for the perimeter of a rectangle is

P = 2l + 2w

so if you substitute, it becomes

P = 2(12) + 2(2)

= 24 + 4

= 28

For the perimeter of a triangle the correct formula would be

P = a + b + c

The missing side in the triangle is 3 because 15 - 12 is 3.

If you substitute, it becomes

P = 2 + 3 + 6

P = 11

If we add both perimeters together we get the full perimeter of the figure which is

28 + 11 = 39

I am not sure if you wanted the answer as well but just in case :)

How are addition properties and subtraction rules helpful when solving problems
snow_lady [41]
For the sum we have the following properties:
 The properties are commutative, asosiative, distributive and neutral element.

 Commutative property: When two numbers are added, the result is the same regardless of the order of the addends.

 Associative property: When three or more numbers are added, the result is the same regardless of the order in which the addends are added.

 Neutral element: The sum of any number and zero is equal to the original number.

 Distributive property: The sum of two numbers multiplied by a third number is equal to the sum of each summand multiplied by the third number.<span><span>

 </span><span>For subtraction we have:
 
</span><span> The arithmetic operation of the subtraction (subtraction) is indicated by the minus sign (-) and is the opposite, or inverse, operation of the addition. </span><span>That is, it is an arithmetic operation that serves to find the difference between two numbers.
</span><span> 
 In subtraction A - B = D
 </span><span>A is the minuendo
 </span><span>B is the substraendo
 </span><span>D is the difference

 </span><span>Answer:
 </span><span>The properties of addition and subtraction serve to rewrite and simplify calculations.</span></span>
