Step-by-step explanation:
If a+b=50
When b=30
a=50-b
a= 50 - 30
a=20
Therefore 20(a)+30(b)=50
V = (12·15 - 1/2·(12 - 7)·(15 - 5))·8 = 1240 cm³
Answer:
There is no answer. The equation cannot be simplified any further.
Assuming that you have typed 2j/2 correctly, reduce this to j.
Then 2mk + j = n + p
Solving for k:
2mk = n + p - j
n+p-j
k = ---------- (answer)
2m
