Answer:
speed = distance/time
Step-by-step explanation:
The faster a sound wave travels, the more distance it will cover in the same period of time. If a sound wave were observed to travel a distance of 700 meters in 2 seconds, then the speed of the wave would be 350 m/s.
Step-by-step explanation:
So the answer for 33+45+78 is 156.
If you want to check that, you can use inverse operations, so subtract.
156-78=78. (Check 78)
78-45=33 (Check 45 and 33)
Well, now it's checked because we used all the factors of the equation!
So, if 10 cookies cost 2 dollars multiply that by 2 to get 20 cookies ( 4 dollars )
Then divide 2 in half because you need 5 more cookies to get the total 25.
( 1 dollar. )
So that will cost 5 dollars! I did the math myself.
I hope this helped!
I would appreciate it if you gave me a Thanks and a brainliest (:
1. Add 5 to both sides. So x=5. That is a vertical line. The answer is undefined
2. 25- 5 7/8 + 6 1/2
Denominators have to be the same
Multiply 1/2 by 4/4
25-5 7/8 + 6 4/8
25 - 11 11/8
23 16/8- 11 11/8
12 5/8
