If a TV cost $3960.00 and toes on sale during the following week with a 25% discount, what will be the total cost of the TV? but
Free_Kalibri [48]

we have the price of TV is $3960.if we round off to the nearest tens we get same 3960 because we have 0 at the end which means lesser than 5 so 60 will be the nearest ten.

discount =\frac{25}{100} *3960=990

so $990 will be the discount.

and the cost of TV after discount is 3960-990=$2970

Equivalent to a), b), and d). It is NOT equivalent to c).

Step-by-step explanation:

6m + 12 is also equivalent to a) 3(2m+4) because when you distribute, it's 6m + 12. It is also equivalent to b) 3m + 8 + 4 + 3m because if you add them together, you get 6m + 12. It is not equivalent to c) but is do d) 4m + 2(m + 6) cause you use the distributive property then add. I hope this helped and please mark brainliest!

What’s the x intersect of the equation<br> -25 - 12x = -(-8x - 6) -3(5x+12)
erik [133]

-25 - 12x = -(-8x - 6) - 3(5x + 12)

Distributive property.

-25 - 12x = 8x + 6 - 15x - 36

Combine like terms.

-25 - 12x = -7x - 30

Add 12x to both sides.

-25 = 5x - 30

Add 30 to both sides.

5 = 5x

Divide both sides by 5.

x = 1

The x-intersect is 1.
