In the Aaron`s work:
- 2 = - 2 x - 6
and after that:
- 2 - 6 = 2 x
It should be:
- 2 + 6 = 2 x
or: - 2 + 6 = 2 x - 6 + 6
Answer:
A ) Aaron made the error when he subtracted 6.

Marni danced in a contest to raise money for an animal shelter. Marni raised $30 plus $1.80 per minute that she danced. She rais

klio [65]

Total raised: 264

She raised 30 plus 1.80x (x being the number of minutes).

Equation: 264=1.8x+30

To solve for x, you need to isolate x. First, subtract 30 from both sides.

234=1.8x

Now, divide both sides by 1.8.

130=x

Marni danced 130 minutes.

I hope this helps :)

Answer:

$700.8

Step-by-step explanation:

discount = 0.20

You actually pay full price (100% or 1) - discount (20% or 0.20), so 1 - 0.20 = 0.80

If the TV was originally $800, then you pay 0.80 (80%) of it, or

(800)(0.80) = $640.00 dollars.

Tax, 9.5% or 0.095, of $640 is added to the $640, so

Tax = 0.095 + 640 = $60.8

$60.8 + $640 = $700.8

A slice of pizza whose edges form a 32degrees angle with an outer crust edge 4 inches long was found in a gym locker. What was t

liq [111]

Answer:

The diameter was $d=\frac{45}{\pi }$ in.

Step-by-step explanation:

The arc of a circle is given by

$s=r\theta$

where

s = arc length

r = radius of the circle

θ = measure of the central angle in radians.

From the information given

s = 4 in

θ = 32º

To find the diameter of the original pizza, we use the formula of the diameter of a circle

$d=2r$

First, we need to convert the angle to radians

$\theta=32\º \cdot \frac{\pi}{180\º} =\frac{8\pi }{45}$

Next, solve for r from the arc formula

$r=\frac{s}{\theta} =\frac{4}{\frac{8\pi }{45}} =\frac{45}{2\pi }$

Then, we use the diameter of a circle formula

$d=2r=2(\frac{45}{2\pi })=\frac{45}{\pi }$
