To the nearest cent what is $89.95 DVD player 5% discount

Answers

89.95 x 0.05 (5%)
=4.4975

The final cost of the DVD player is 89.95-4.4975
=85.4525
≈ $85.45

Final answer:

5% of $89.95 is $4.4975. After subtracting this discount from the original price, the DVD player costs $85.4525. Rounded to the nearest cent, the final price is $85.45.

Explanation:

To find the cost of the $89.95 DVD player after a 5% discount, we need to first figure out how much 5% of $89.95 is. This is done by multiplying $89.95 by 0.05 (which is the decimal equivalent of 5%).

So, $89.95 * 0.05 = $4.4975. This is the amount of the discount.

Now, to find the final price after the discount, we subtract the discount from the original price. Therefore, $89.95 - $4.4975 = $85.4525.

However, we need to round this to the nearest cent, which makes it $85.45.

Solve the equation -8v – 5 = -21 for v. A.-2 B.-1 C.2 D.4

Answers

Answer: v = 2

Step-by-step explanation:

-8v - 5 = -21

Make v the subject of the equation

-8v = -21 + 5

-8v = -16

Divide both sides by -8

v = 2

Check:

Slot in the value of v into the equation

-8v - 5 = -21

-8 (2) - 5 = -21

-16 - 5 = -21

I hope this is clear, please mark as brainliest answer.

A batch of cookies for 3/4 cup of flour.You want to make 1/2 of a batch.How much flour do you need?

Answers

For the total batch you need 3/4 cup and you only want one half of that, so you need to multiply 3/4 by 1/2

$(3)/(4) * (1)/(2) = (3)/(8)$

First will make the fraction is easier by turning it into 6/8 but because we’re halving it the we only halve the numerator, so it’s 3/8.

We flip the 2nd fraction and multiply.

5/3 * 4/1 = (5 * 4)/(3 * 1) = 20/3 = 6 2/3

So the correct choice should be 'none of the above' unless you made a mistake in your question.

PLEASE HELP WORTH 10 POINTS! AKA SHOW WORK:)

Answers

1)
3x-2y=14
y=5x

So we plug in y=5x into 3x-2y=14

We get:

3x-2(5x)=14
3x -10x=14
-7x=14
x=-2

So we found x, now we need to find y. We can simply plug in x into the equation and get y.

y=5x
y=5(-2)
y=-10

So your answer will be (-2,-10).

2)
x-2y= -2
y= 2x+4

Once again plug in y=2x+4 into x-2y=-2

x-2(2x+4) = -2
x-4x-8=-2
-3x-8=-2
-3x = 6
x= -2

Now we plug back in x and solve for y :)

y=2x+4
y=2(-2)+4
y=-4+4
y=0

So our solution would be (-2,0).

3)
x+2y=-7
x-5y=7

Multiply the second equation by -1

-x+5y=-7

Now add that equation with the other one:

x+2y=-7
+
-x+5y=-7
-----------------
7y=-14
y=-2

Now plug in y=-2 and solve for x

x+2y=-7
x+2(-2)=-7
x+(-4)=-7
x-4=-7
x=-3

So your solution would be (-3,-2).

1)

$3x-2y=14\n \n y=5x$

We know y's value. Let's plug it in the equation.

$y=5x\n \n 3x-2\cdot (5x)=14\n \n 3x-10x=14\n \n -7x=14$

Divide both sides by -7.

$x=-2$

Now we have x's value. Let's plug it in the equation to find y.

$x=-2\n \n y=5x\n \n y=5\cdot -2\n \n y=-10$

Solution,

(-2, -10)

2)
$x-2y=-2\n \n y=2x+4$

Again we have y's value. Let's plug and solve.

$y=2x+4\n \n x-2\cdot (2x+4)=-2\n \n x-(2\cdot 2x+2\cdot 4)=-2\n \n x-4x-8=-2\n \n -3x-8=-2\n \n -3x=-2+8\n \n -3x=6\n \n x=\frac { 6 }{ -3 } \n \n x=-2$

Now we have x's value let's solve for y.

$x=-2\n \n y=2x+4\n \n y=2\cdot (-2)+4\n \n y=-4+4\n \n y=0$

Solution,

(-2, 0)

3)

$x+2y=-7\n \n x-5y=7$

Let's first multiply the first equation by -1

$-1\cdot (x+2y)=-1\cdot -7\n \n -x-2y=7$

Then let's add these new equation and the second equation.

$-1\cdot (x+2y)=-1\cdot -7\n \n -x-2y=7\n \n x-5y=7\n \n (-x-2y)+(x-5y)=7+7\n \n -x+x-2y-5y=14\n \n -7y=14\n \n y=\frac { 14 }{ -7 } \n \n y=-2$

Now we have y's value let's plug it and solve for x.

$y=-2\n \n x+2y=-7\n \n x+2\cdot (-2)=-7\n \n x-4=-7\n \n x=-7+4\n \n x=-3$

Solution,

(-3, -2)
