Answer:
36 parts water
Step-by-step explanation:
3/9 = 1/3 = for every 1 part concrete, it's 3 parts water.
12/x = 1/3; x = 36
so, 12 x 3 = 36
If I was u I would use Photomath Bc it is super easy and answers almost all your answers
1) 5
2) zero
3) <span>Step 1: 12x + 15 = 12
Step 2: 12x = −3
4) 10
5) 2
This took me a long time to do so I hope this was beneficial :)) !! (btw I am absolutely sure about every answer. I checked my work plenty of times :)</span>
