Answer:
405
Step-by-step explanation:
Since
2 : 9 = 90 : X
Then we know
9/2 = X/90
Multiplying both sides by 90 cancels on the right
90 × (9/2) = (X/90) × 90
90 × (9/2) = X
Then solving for X
X = 90 × (9/2)
X = 405
Therefore
2 : 9 = 90 : 405
The answer to your question is : C. the invasion of Belgium
Answer: y=2
Step-by-step explanation:
2x+3y=14 - 2x-y=6 = 4y=8
y=2
If you need x, just insert y into the equation and work out x from there
2x-2=6
2x=8
x=4
I assume it's 43 <em>thousand</em> and 335, not 43 <em>point</em> 335.
The first 3 from the right is for tens, the second is 10 times stronger because it's for hundreds and the fourth is again 10 times stronger because it's for thousands. Hopefully that's what you meant :)
Answer:
1/2
Step-by-step explanation:
x + 9 = -15x = [1]
x - x + 9 = -15x -x = 1
9 - 1 = -16x
8 = 16x
8/16 = 16/16x
1/2 = x
Hope this helps
