Round 6 6/13 to the nearest whole number.

Answers

6.

1/3 is not 1/2 or more than 1/2 so you have to round down.

Rounding to the nearest whole number involves writhing out the value of a number to the nearest integer value. Hence, the number would be written as 6

Converting the fractional value to decimal ; 6 61/3 = 6.461

Since the first digit after the decimal point is less than 5, we round to 0

Therefore, the number would be written as 6 (nearest whole number).

If 2x+3y=6 and -5x+2y=4 then what is x and y??

Answers

Answer:

x=0 y=2

Step-by-step explanation:

2x+3y=6 .... 1

-5x+2y=4 .... 2

Multiply 5 with equation 1 and multiply 2 with equation 2

Then we get

10x+15y=30

-10x+4y=8

-10x and +10x get canceled so 19y=38

y=38/19=2

substitute y value in equation 1 or 2 and find the value to get x

Describe two ways the Distributive Property can be used to write equivalent expressions.

Answers

For example, apply the distributive property to the expression 3 (2 + x) to produce the equivalent expression 6 + 3x; apply the distributive property to the expression 24x + 18y to produce the equivalent expression 6 (4x + 3y); apply properties of operations to y + y + y to produce the equivalent expression 3y.

The two ways for the Distributive Property can be used to write equivalent expressions is explained below:

Distributive Property:Here we apply the distributive property to the expression 3 (2 + x) to generate the equivalent expression 6 + 3x.Now apply the distributive property to the expression 24x + 18y to generate the equivalent expression 6 (4x + 3y)
