(x , 5/2)......so y = 5/2.....so do some subbing

y = x - 1/2
5/2 = x - 1/2....add 1/2 to both sides
5/2 + 1/2 = x
6/2 = x....reduce
3 = x

now check it...(3, 5/2)
y = x - 1/2
5/2 = 3 - 1/2
5/2 = 6/2 - 1/2
5/2 = 5/2 (correct)

so x = 3 <==

The number sentence 4x6=6x4 is an example of the what property
monitta

Answer:

commutative property of multiplication

Step-by-step explanation:

The value of the product of the given equation remain the same while the order is reversed

The number sequence 4 × 6 = 6 × 4 is an example of the commutative property of multiplication

Reason:

The given number sentence is 4 × 6 = 6 × 4

Required: The property the number sentence is an example of (represent)

Solution:

The difference between the left and right expression is that the order of the

values being multiplied is changed or reversed (commute)

Therefore, the number sentence states that the value of the multiplication

of two variables remain equal when the places of variables are

interchanged as follows; a × b = b × a

a × b = b × a is an example of commutative property of multiplication

Therefore;

4 × 6 = 6 × 4 is an example of the commutative property of multiplication

The temperature fell by 15 degrees Fahrenheit today.
katrin2010 [14]
<h3>Answer is   -15</h3>

We read this out as "negative 15" or you could write "negative fifteen".

The negative indicates the temperature went down. It doesn't necessarily mean that the final temperature is -15 degrees.

For example, if it starts being 50 degrees F, and drops by 15 degrees, then 50+(-15) = 50-15 = 35 degrees is the temperature after that drop. It might help to use a vertical number line.

16 The perimeter of the pentagon is equal to the perimeter of the square.
STatiana [176]

7x+2

Step-by-step explanation:

add all the sides of the pentagon and make it equal to the perimeter of the square which is 4y

sides of the pentagon are

5x+3

2x+3

7x+4

9x-10

5x+8

28x+8=4y

7x+2 = y

7x+2 = answer

another way :

in a standardized test you may want to use real numbers

make x equal a prime number like 3

so then the sides are

18

9

25

17

23

=

92

then divide by 4

23

then divide by 3

which is 7 remainder of 2

which is

7x+2

Can someone explain the steps to me. Please?
Nina [5.8K]
Actually i’m pretty sure what you would do is multiply 24,50 by 5, because he wrote 5 checks of that amount. then you would subtract that from the total of $450. Then multiply 45 by 3 because he deposited three deposits of $45, and add that amount to the number you got after subtracting 24.50
