If this is just an expression, then all you have to do is combine like terms, or groups of numbers and variables that have the same variable.
When simplified, you get the equation
-12+ 16r or
-18+6+3r+13r=16r-12
The answer is multiplication.
15 x 4 = 60
60 divided by 4 = 15
There are 4 times as many ribbons in the large ones as in the small one.
Answer:
10 rounds.
Step-by-step explanation:
Let x represent number of rounds around the field.
We have been given that the distance around our playing field is 300 meters long. So distance covered in x rounds would be
meters.
We are also told that your coach wants you to run 3 kilometers. Let us convert 3 km in meters.
1 km = 1000 m
3 km = 3*1000 m = 3000 m
Now, we will equate total distance covered in x rounds by 3000 as:
![300x=3000](https://tex.z-dn.net/?f=300x%3D3000)
![\frac{300x}{300}=\frac{3000}{300}](https://tex.z-dn.net/?f=%5Cfrac%7B300x%7D%7B300%7D%3D%5Cfrac%7B3000%7D%7B300%7D)
![x=10](https://tex.z-dn.net/?f=x%3D10)
Therefore, you need to run 10 times around the field.
Let the number be x
2x-16=42
2x=42+16
2x= 58
x=29
not sure if it’s right!!
