Let the frequency be 'f' and wavelength be 'w'
,
w= 100 m and f = 3,000 kilohertz
Plug in the above values to find k
3000 =
To find k, multiply both side by 100
3000(100) = k
k = 300,000
So equation becomes,
w= ? f = 500 kilohertz
500 =
w =
w = 600 m
Nothing further can be done with this x=3a
1.) The first thing you want to do is get the -12x alone. You can do this by adding that -17 to the -89 on the right side of the equal sign.
2.) Once you get -12x = -72, you need to get just the variable alone. What's the opposite of multiplication? Division. Divide -12 on each side to get x alone. You should end up with x = 6.
Answer: 340
Step-by-step explanation:
10 x 5 = 50
10 x 5 = 50
10 x 8 = 80
10 x 8 = 80
8 x 5 = 40
8 x 5 = 40
50 + 50 + 80 + 80 + 40 + 40
100 + 160 + 80
340
Answer:
64/9 or 7 or 1/9
Step-by-step explanation:
4 3/9 + 2 7/9 = 64
9
= 71
