The speed of light is faster than the speed of sound. So that's why you see a flash of lightning before the roar of thunder. If you heard it at the same time as you saw it, well I will be praying for you. It would literally be exactly where you are. If you hear the thunder a long time after the flash, it means the lightning is far away.
T/5=miles away when T is time from the strike of lightning to hearing thunder
Answer:
x = 9
Step-by-step explanation:
First, we want to isolate variable x on the left side of the equation. We can do this by adding 13 to both sides.
x - 13 + 13 = - 4 + 13
x = 9

Answer:
x > 3
Step-by-step explanation:
8x - 6 > 12 + 2x....,just move the values with variable x to one side and those without to the other side
; 8x - 2x > 12 + 6
; 6x > 18...., then divide by 6,both sides of the inequality
; x > 3
Answer:
x:y:z = 12:3:2
Step-by-step explanation:
x = 4y
2y = 3z ⇒ 4y = 6z
⇒ x = 4y = 6z
To find x:
Multiply the coefficients of y & z: 4 × 6 = 24
To find y:
Multiply the coefficients of x & z: 1 × 6 = 6
To find z:
Multiply the coefficients of x & y: 1 × 4 = 4
⇒ x:y:z = 24:6:4 = 12:3:2
