Answer:
3
Step-by-step explanation:
Wavelength is usually denoted as letter lambda (λ); it is equal to the speed (v) of a wave train in a medium divided by its frequency (f): λ = v/f. Waves of different wavelengths.
formula: λ = v/f
solution: λ= 30m/s / 10Hz
= 3
X + 4x = 40
5x = 40
5x/5 = 40/5
x = 8
1x 8 = 8
4x 8 = 32
Check=
8 + 32 = 40
The numbers are 8 and 32
Assuming you are talking about the rectangle,
width = area/lenght
Answer:
1/3
Step-by-step explanation:
You can try it I keep getting 3 so maybe that’s the answer
Answer:
-5x+3 OR 5x-3
Step-by-step explanation:
You find the inverse by replacing the x with the y, and solving for y. Doing this actually gives you -5x+3 but in this case, the closest answer would be 5x-3.
UPDATE: -5x + 3 can be written as 3 - 5x lol
