Answer:
The distance traveled in 36s is 12440 m
Step-by-step explanation:
Given;
speed of sound, v = 340 m/s
distance traveled by the sound, d(t) = 340t
time of travel, t = 36 s
Distance is given as;
distance = speed x time
d(t) = 340t
d(36) = 340(36)
d = 12440 m
Therefore, the distance traveled in 36s is 12440 m

Answer:
x=4
Step-by-step explanation:
In order to solve for x, we must isolate x on one side of the equation.
x+3x+5=21
First, combine like terms. x and 3x are both terms with variables, and can be combined.
(x+3x) + 5=21
4x + 5=21
5 is being added to 4x. The inverse of addition is subtraction. Subtract 5 from both sides of the equation.
4x+5-5= 21-5
4x= 16
x is being multiplied by 4. The inverse of multiplication is division. Divide both sides by 4.
4x/4=16/4
x= 16/4
x=4
Let's check our solution. Plug 4 in for x and solve.
x+3x+5=21
4+3(4)+5=21
4+12+5=21
16+5=21
21=21
This solution checks out, so we know our answer is correct.
x is equal to 4, x=4.
Only one that would make sense is 1/12
