Vlad [161]

Answer:

<em>The expression for final cost of the DVD is  0.9064y</em>

Step-by-step explanation:

Jessica purchased a DVD that was on sale for 12% off.

If the original price of the DVD is  y , then the amount of discount on sale will be:  0.12y

So, the selling price of the DVD = (y-0.12y)= 0.88y

The sales tax in her county is 3%. So, the amount of sales tax on the selling price will be:  (0.88y\times 0.03)= 0.0264y

Thus, the expression for final cost of the DVD is:  (0.88y+0.0264y)= 0.9064y

4(1.5c+6)-2c=-9 I need a help my teacher doesn't help
harkovskaia [24]
4(1.5c+6)-2c=-9 so we distribute the 4 to 1.5 tand 6 and it will now be broken into this ==>   6c+24-2c=-9 ok now we most combine like terms so the we do 6c-2c= 4c so the problem is now 24-4c=-9 ok now i think we need to solve for c so we subtract 24 to -9  because it is negative it is now -33 so the problem is -4c=-33 divide by -4 and you will get your answer. I hope this helped and is correct.

A rectangle has a perimeter of 12 centimeters and a height of 5 centimeters. What is the length of the base?
Gwar [14]

Answer:

1 cm

Step-by-step explanation:

We know that the formula for perimeter is<u> 2(l+w) or l+l+w+w</u>

We know that the height is 5 cm so that means <em><u>w= 5</u></em> also that there is 5 cm on both sides of the rectangle. So 5+5=10 so that means that the length of the rectangle is <em><u>1 cm</u></em> if you add the length together you 2 when you add the width you get 10. <em>10+2=12.</em>
