The ratio is 6:18 and you are trying to find out what are blue. You divide 240 by 6 and get 40. You then multiply 40 x 18 and get 720.
X= 10 y= 9 the difference between the two numbers is one and they equal 19
Answer:
270
Step-by-step explanation:
Convert 15% into a decimal: .15
Then multiply 1800* 0.15
This gives you 270
Calculate the products
5x+6x-21x+2
Combine like terms
-10x+2
Here is a step-by-step method for solving them:
1. Substitute y = uv, and
dy/dx = u
dv/dx + v
du/dx
into
dy/dx + P(x)y = Q(x)
2. Factor the parts involving v
3. Put the v term equal to zero (this gives a differential equation in u and x which can be solved in the next step)
4. Solve using separation of variables to find u
5. Substitute u back into the equation we got at step 2
6. Solve that to find v
7. Finally, substitute u and v into y = uv to get our solution!
I'm so sorry if the explanation is confusing but I hope it's helps you to solve ^ ^
