He's using the graduated cylinder method. I think the volume might be between 15 and 20. (It's kind of not obvious...)
Answer:
N = 10
Step-by-step explanation:
-17+ x/5 = 33
You have to find x, in this case is N
x/5 = 33 + 17
x/5 = 50
x= 50/5
x =10
N= 10
Answer:
x = 20
y = 100
Step-by-step explanation:
To figure out x do this.
3x + 2x = 7x - 40 (collect like terms)
5x = 7x -40 (subtract 7x on both sides)
-2x = -40 (divide by -2 on both sides)
x = 20
Plug in to get y
Since 7x - 40 and y are vertical they equal the same amount
7(20) - 40 = y (multiply 7 by 20)
140 - 40 = y (collect like terms)
100 = y
Hope this helps ya! Keep smiling!
Answer:
y=1
Step-by-step explanation:
6=2(y+2)
6=2y+4
2=2y
y=1
Answer:
it's 1/7 I think in fraction form hoped I helped :D
Step-by-step explanation:
1/5 x 5/7 = 1/7 (in simplest form)
