Answer:
idek
Step-by-step explanation:
If there are 8 marbles in a group , and 5 out of every 8 is red, than in six groups there would be 5, 10, 15, 20, 25, 30 red marbles.
This lists the group of 6 sets.
30 red marbles in 6 sets.
3w-13w=-20
Combine like terms
-10w=-20
divide both sides by -10
w=2
0.75 because 100cm = 1m so you just move the decimal to the right by 2
Start with the brackets. Then do 5 multiply 1 which is 5 then divide that 5 from 20 which gets you 4. Times the outside of the brackets with the inside which will give you the answer of 16
