Answer:
X=16
Step-by-step explanation:
10x-8=9x+8
First you have to simplify.
10x-9x=1x
So now the equation looks like this
x-8=8
Now you have to get x by itself
-8+8=0 and we have to do the same thing on both sides of the equal sign 8+8=16
The equation now looks like this x=16
And that's your answer
Answer:
Scott will be represented as S
Step-by-step explanation:
The correct answer is
c) Neither person is correct because light does not change frequency when it travels through different media
we have given that The column on the right is labeled speed of light in meters per second and are all times 10 Superscript 8 Baseline with entries 2. 25, 2. 99, 1. 97, 1. 24.
<h3>What happened when light travels through the different media?</h3>
light changes both wavelength and speed when it travels through different media, but the frequency remains the same
light changes both wavelength and speed when it travels through different media, but the frequency remains the same.
Therefore the option c is correct that
Neither person is correct because light does not change frequency when it travels through different media
