B = 2A/h
The way you would get this is first by clearing the fraction. So in order to clear the fraction, you have to multiply the equation by the denominator.
2(A = 1/2bh)
2A = 1bh
2A = bh
Then you have to isolate the variable. So you'd divide bh by h in order to get b by itself. So you'd end up with:
2A/h = bh/h
2A/h = b
Set up a proportion:
y = 35 when x = 7
y = ? when x = 10
To get x from 7 to 10, you have to multiply by 
. Therefore, you do the same to 35, and you get:
And your answer is 50 :)
The submarine's new position is 240 feet below sea level.
Answer:
Let the smaller number be x
Then the sum is
(6 + 2x) + x = 27
We now find for x
2x + x + 6 = 27
3x + 6 = 27
3x = 27-6
3x = 21
x = 21/3
x = 7
Therefore the smaller number is 7
The larger number is (2×7) + 6 = 20
Yes that is the answer 19
