DVD weighs 6lbs and game machine weighs 14lbs, so in this case A
in my mind this is what i did...
3(gameMachines) + 5(DVD) = 72lbs
3(gameMachine) + 1 (DVD) = 48lbs
when you subtract, since there is the same number of game machines, they cancel out and your left with
4(DVD) = 24
1 DVD = 6
then just fill in DVD in one of the equations to get the weight of gameMachine
3(gameMachines) + 5(6) = 72lbs
3(gameMachines) = 42
gameMachine = 14
Step-by-step explanation:
- 7x + 3x - 18 = 6(x + 3) === Given
- 10x - 18 = 6(x + 3) === Combine Like Terms === 7x + 3
- 10x - 18 = 6x + 18 === Distributive Property === 6(x + 3)
- 10x - 18 - 6x = 18 === Subtraction Property of Equality === -6x both sides
- 4x - 18 = 18 === Combine Like Terms === 10x - 6x
- 4x = 18 + 18 === Addition Property of Equality === +18 both sides
- 4x = 36 === Combine Like terms === 18 + 18
- x = 36 / 4 === Division Property of Equality === /4 both sides
- x = 9 === combine like terms??
That doesn't use the multiplication property but that's all of the rest of them.
55 g x 25 days = 1375 grams
1gram = 0.001 kg
1375 x 0.001 = 1.375 kg
round the answer as needed
You need to convert your 3200 sq ft into yards which is 355.556 sq yards then you divide 355.556 by 25 to get 14.22224 bags of seed needed
