A store Is having a sale where movies are 15% off their original price. a movien is on sale for $22.10 what was the orgial price
sergeinik [125]
X= original $

Original $ - % of original $= total $

x - 15%x= $22.10
x- 0.15= 22.10
Combine like terms
0.85x= 22.10
Divide both sides by 0.85
x= $26 original price

Hope this helps! :)

What is the solution for the system of equations? 2y=4x-12 and y=-2x+2
pashok25 [27]

2y = 4x - 12 \\ y =  - 2x + 2 \\  \\ 2( - 2x + 2) = 4x - 12 \\  - 4x + 4 = 4x - 12 \\ 4 = 8x - 12 \\ 16 = 8x \\ 2 = x \\  \\ y =  - 2(2) + 2 \\ y =  - 4 + 2 \\ y =  - 2

The illuminance of a surface varies inversely with the square of its distance from the light source. If the illuminance of a sur
lesya692 [45]

Answer: b) 6

Step-by-step explanation:

Given : The illuminance of a surface varies inversely with the square of its distance from the light source.

i.e. for d distance and l luminance , we have

d^2\times l=k , where k is constant.       (1)

If  the illuminance of a surface is 120 lumens per square meter when its distance from a certain light source is 6 meters.

From (1), we have

\Rightarrow (6)^2\times 120=k\\\\\Rightarrow\ k=4320   (2)

For the distance (d) corresponds to the illuminance to 30 lumens per square meter , we have

d^2\times 30=k

Put value of k , we get

d^2\times 30=4320\\\\\Rightarrow\ d^2=\dfrac{4320}{30}=144\\\\\Rightarrow\ d^2=144\\\\\Rightarrow\ d= 12

Then , the number of meters should the distance of the surface from the source be increased= 12 meters- 6 meters = 6 meters.
