Answer:

(8n)(-77)=-77(n*8)

We move all terms to the left:

(8n)(-77)-(-77(n*8))=0

We add all the numbers together, and all the variables

8n(-77)-(-77(+n*8))=0

We multiply parentheses

-616n-(-77(+n*8))=0

We calculate terms in parentheses: -(-77(+n*8)), so:

-77(+n*8)

We multiply parentheses

-616n

Back to the equation:

-(-616n)

We get rid of parentheses

-616n+616n=0

We add all the numbers together, and all the variables

=0

n=0/1

n=0

the property is Associative Property

Step-by-step explanation:

this one was kinda hard pls let me know it its right or not

write The equation of the line that passes through the point parentheses (6 , 4) and is parallel to the equation 2X plus 3Y equa
aliina [53]

Answer:

2x + 3y - 24 = 0

Step-by-step explanation:

2x + 3y = 18

3y = -2x + 18

y = \frac{-2}{3}x + 6

m = -2/3

y - 4 = -2/3(x - 6)

3y - 12 = -2x + 12

2x + 3y - 24 = 0

We have the given expression to find the total cost which is

Total = c + 0.07c

Substituting our given data into the expression we have

Total = 25 + 0.07*25

Total = 25 + 1.75

Total = $26.75
