Answer:
1. a
2. c
3. e
Step-by-step explanation:
1. a because she ran 5 miles on friday and ran x miles before friday. we know she had ran a total of 20 miles so we have x+5=20
2. there is a total of 20 clubs andre's school, 5 times more than is cousin's school. we have 20 =5x
3. 20 cats get 5 cups of food. each got an x amount. we get 5 =20x
The relationship between wavelength and frequency is expressed by the equation λν=c where λ is the wavelength, v is the frequency and c is the speed of light which has a value of 3x10^8 m/s.
λν=c
λ(3 × 10^9)= 3x10^8
λ = 0.1 m
Hope this answers the question.
I don't know how you expand it but the answer is 3x + 25 unless that's expanding.
