First divide both sides by 3 and you’ll get
(y+12)=8 “y” will then equal -4 as -4+12=8=8 so therefore 18y= -72
Answer: 1/24
Step-by-step explanation:
If one fourth was split into six pieces, you would multipli six by one fourth to get 1.24==
My mom has trouble understanding math... I decided to give her an easy equation. 3/6 km+1/5km = 15/40 +8/40. She asked me what I did. I told her that I multiplied both equations to get a denominator of 40. Then she said "what about those top ones" "oh... well" I said " whatever I multiplied to the bottom I have to do to the top!" Anyway back to the problem. Well... somehow all of this equals 23/40. This is because when you add 15 + 8 that equals 23! So wait a sec what is this on the bottom she asked. well... I am unsure why don't you tell me. She said that the 4 needed to have been added to it.. but the four was too much so they took away one. Good enough! The answer is 3 and 17/40
(-6,2) is the rotation of 90 degrees counter clockwise

Answer:
Step-by-step explanation:
1 m is 100 cm, so the volume is ...
V = LWH
V = (100 cm)(50 cm)(4 cm) = 20,000 cm³ . . . volume
__
The mass is ...
(20,000 cm³)(2.7 g/cm³) = 54,000 g = 54 kg
The mass of the block is 54 kg.
