D'Angelo bought two shirts at a special sale. He paid the full price of $19.99 for one shirt and got a second shirt of the same price for half off. If the sales tax rate is 8.5%, how much sales tax did D'Angelo pay for the two shirts?

Answer:

B(2.75,2.5)

Step-by-step explanation:

B(x,y)

Bx= Ax+Cx 1 + 4.5 5.5

---------- = -------------- = --------- = 2.75

2 2 2

By = Ay+Cy 1 + 4 5

---------- = ----------- = ---------- = 2.5

2 2 2

coordinates of point B(2.75,2.5)

Step-by-step explanation:

4n-3=-2n+9, we move the variables in one side and numbers on the other side

4n+2n=9+3

6n=12

divide by 2

Answer:

4,-2

Step-by-step explanation:

The line passes through the Y Axis and slopes 4 and -2.

Answer:

slope = - [tex]\frac{7}{4}[/tex]

Step-by-step explanation:

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 3, 4) and (x₂,y₂ ) = (1, - 3) ← 2 points on the line

m = [tex]\frac{-3-4}{1+3}[/tex] = - [tex]\frac{7}{4}[/tex]

Answer: The answer is 8

Step-by-step explanation: first you solve 16 to the 1.5 power (3/2=1.5) and that gives you 64. Then 64 to the .5 power (1/2=.5) and that gives you 8.

Answer:

c = 2.99m+ 6.85

Step-by-step explanation:

one time fee of 6.85

2.99 per movie rental

in other words you must pay 6.85

and 2.99 times the number of movies you watch

m = movies watched

c = cost

therefore

c = 2.99m+ 6.85

watching 13 movies at movie mania would mean that m (movies watched) would be 13

put that into the equation:

c = 6.85+ 2.99(13)

c =  6.85+ 38.87

c = 45.72

Answer:

1 solution

Step-by-step explanation:

4x + 5 = 6(x+3) - 20 - 2x

4x + 5 = 6x + 18 - 20 - 2x

4x + 5 = 4x -2

X = 3 therefore, there is only one solution

Answer:

The perimeter is 80

Answer:

P = 80

Step-by-step explanation:

w = 10

L = 10 x 3

L = 30

P = L + L + w + w

P = 30 + 30 + 10 + 10

P = 80

Answer:

a=(2p-3n)/12

Step-by-step explanation:

-12a=-2p+3n

Or, a= -{(-2p+3n)/12}

a=(2p-3n)/12

Hi there!

So what we have to do here is...

turn 2³ - 1 into 2·2·2-1=4·2=8-1=7.

[tex]\frac{35}{7}=5[/tex]

Final Result: 5

Answer:

We have the angles as;

8.9 and 72.2

Step-by-step explanation:

When two angles are complementary, they add up to 90

Let the first angle be x , the second angle is 72.2 degrees less and it is x-72.2

Thus, mathematically;

x + x - 72.2 = 90

2x = 90+ 72.2

2x = 162.2

x = 81.1

x = 81.1

The other will be

81.1 - 72.2 = 8.9

Answer:

Y=-1

Step-by-step explanation:

-4(y-2)

-4y+8=12

-8.       -8

-4y=4

-4.  -4

y=-1

Answer: Y = -1

Step-by-step explanation:

This is solved using the distributive property.

1. Distribute, so now it should look like -4y + 8 = 12

2. Now subtract the 8 from both sides to isolate -4y = 4

3. Divide -4 on both sides to get y = -1

Answer:

y=4/3x+0

Step-by-step explanation:

slope intercept form works right?

y=mx+b

the m is the slope, and the problem gives us the slope. (4/3)

the b is the y intercept (where the line goes through the y) so on our coordinates, the second number is the y, so we have y=4/3x+b

HTH!!

Answer:

Everything in red works

Step-by-step explanation:

Answer:

8.88

Step-by-step explanation:

With reference angle 42°

hypotenuse (h) = 12

base (b) = x

Now

cos 42° = b / h

0.74 = x / 12

x = 0.74 * 12

x = 8.88
