H = 2f / (m+1)
[multiply by (m+1)]
h(m+1) = 2f
[divide by 2]
f = (h (m + 1)) / 2
3b / (b+2) = 12 / (b+2)
[multiply by (b+2)]
3b = 12
[divide by 3]
b = 4
3 / (6x + 1) / 2 = 8 / (x + 4) / 3
[multiply both denominators to mike one denominator]
3 / 8(6x+1) = 8 / 3(x+4)
[expand brackets]
3 / (48x + 8) = 8 / (3x + 12)
[multiply by (48x + 8)]
3 = 8(48x + 8) / (3x+12)
[multiply by (3x+12)]
3(3x +12) = 4(48x + 8)
[simplify]
9x + 36 = 192x + 32
173x = 4
x = 4 / 173

Answer:
He would need 
cups of salt.
Step-by-step explanation:
We are given that,
The recipe requires 
cups of flour and 
teaspoons of salr.
As Nick wants to make the recipe using 1 cup.
Let the amount of salt needed = x
The ratio of the flour and salt will be same.
So, we have,
i.e. 
i.e. 
i.e. 
Thus, he would need cups of salt if 1 cup of flour is used.
Answer:
(5, - 2)
Step-by-step explanation:
2x+y>3
x-y>1
2x + y > 3 - - - - (1)
x - y > 1 - - - (2)
Using trial and error method :
Using :
(5,-2)
2x + y > 3
2(5) + (-2) > 3
10 - 2 > 3
8 > 3 (true)
x - y > 1
5 - (-2) >1
5 + 2 > 1
7 > 1 (True)
For 0,5
2x + y > 3
2(0) + (5) > 3
0 + 5 > 3
5 > 3 (true)
x - y > 1
0 - (5) >1
-5 > 1
--5 > 1 (false)
Also, all other options do not hold true for bitb inequality statements, hence answer is (5, - 2)
The value of z₁ / z₂ = (4 - j) / (2 + 5j) in euler form given as 
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more variables and numbers.
z₁ / z₂ = (4 - j) / (2 + 5j)
= [ (4 - j) / (2 + 5j)] * [ (2 - 5j) / (2 - 5j)] = 0.448 + 0.62j = 0.766∠54.2°
The value of z₁ / z₂ = (4 - j) / (2 + 5j) in euler form given as
