Answer:
2.04 km
Step-by-step explanation:
there are 1,000 m in 1 km
she was 680 x 3 meters = 2,040 m
2,040 m = 2.04 km
Given:
The equation is:
To find:
The value of n in terms of x.
Solution:
We have,
It can be written as
![[\because a^ma^n=a^{m+n}]](https://tex.z-dn.net/?f=%5B%5Cbecause%20a%5Ema%5En%3Da%5E%7Bm%2Bn%7D%5D)
On comparing the exponents, we get
Add 1 on both sides.
Divide both sides by 2.
Therefore, the value of n is terms of x is 
.
There are 20 people in the class room.
One way I set this word problem up is by using the equation 88-4x=8. X would stand for the amount of classmates in the class, 88 would stand for your total pieces of gum and 8 would stand for the remaining pieces left.
With the equation 88-4x=8 you want to subtract 88 from both sides to get the equation -4x=-80. Last you want to isolate x by dividing -4 on both sides to finally get x=20. 20 people in the class room.
Answer:
$8
Step-by-step explanation:
320 x 20% = 64
64 x (1/8) = 8
I hope this helped!
