I honestly have no idea how to solve this question
8c=5c+21

Answers

Answer 1

Answer: Remember this rule: Whenever you try to isolate the variable do the same operation to both sides
Using the rule above subtract 5c from both sides getting 3c = 21
Divide by 3 to both sides
Now you have c = 7
Thats you answer, if you have anymore questions just PM me

Answer 2

Answer: Well, subtract 5c from both sides, so cross out 5c and do 8c-5c which is 3c. S 3c=21. 21 divided by 3 is 7. So c is. 7.

Answers

The equation to find the volume of a cylinder is V= $\pi$ ×r²×h. To find r you just divide the diameter which is 10 by 2 so r is 5. Just plug everything in and solve, V= $\pi$ ×5²×243.84. You should get V≈19,151.15

Anaida completed her homework in 23 minutes on Sunday. on saturday she needed 3 times as much time how much time does she spend on homework both days together

on Saturday she finished her homework in 23*3 = 69 min

Sunday in 23min

how much time does she spend on her homework the two days together:

69+23 =92min =1h32min
