Which statements about the Commutative Property of Multiplication are TRUE? Select all that apply. A. The property applies to al

musickatia [10]

Answer:

b) The property states that ab is equivalent to b a

Step-by-step explanation:

<em>Commutative property</em>:-

the commutative property , when we multiply two integers , the answer we get after multiplication will remain the same, even if the position of the integers are interchanged.

Let 'a' and 'b' be the two integers , then ab = b a

Example:-

. 1 X 2 = 2 X 1 = 2

. 12 X 5 = 5 X 12 = 60

Which point lies on the graph of the equation 10y = 3x - 11?

GaryK [48]

Answer:

A. (2,-0.5)

Step-by-step explanation:

A pair of coordinates is always (x,y) so

If you insert the numbers into the equation you get

10(-0.5) = 3(2) - 11

-5 = 6 - 11

-5 = -5

Therefore (2,-0.5) is the point that likes on the graph

The larger of two numbers is twice the smaller increased by five. Find the two numbers if three times the larger exceeds double

melomori [17]

Answer:

Larger number is 13 and Smaller number is 4.

Step-by-step explanation:

Let the larger number be x.

Also let the smaller number be y.

We need to find the two numbers.

Given:

The larger of two numbers is twice the smaller increased by five.

framing in equation form we get;

$x=2y+5$ ⇒equation 1

Also Given:

Three times the larger exceeds double the smaller by 31

$3x=2y+31$ ⇒equation 2

Now Substituting the value of x from equation 1 in equation 2 we get;

$3(2y+5) = 2y+31$

Now Using Distributive property we get;

$6y+15 = 2y +31$

Combining the like terms we get;

$6y-2y = 31-15$

Now Using Subtraction property we get;

$4y =16$

Now Using Division property we get;

$\frac{4y}{4}=\frac{16}{4}\\\\y =4$

Now Substituting value of y in equation 1 we will find the value of x.

$x=2y+5\\\\x = 2\times4+5\\\\x=8+5\\\\x=13$

Hence Larger number is 13 and Smaller number is 4.
