Answer:
n=-9
Step-by-step explanation:
Solution for -8-5n=64+3n equation: Simplifying -8 + -5n = 64 + 3n Solving -8 + -5n = 64 + 3n Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '-3n' to each side of the equation. -8 + -5n + -3n = 64 + 3n + -3n Combine like terms: -5n + -3n = -8n -8 + -8n = 64 + 3n + -3n Combine like terms: 3n + -3n = 0 -8 + -8n = 64 + 0 -8 + -8n = 64 Add '8' to each side of the equation. -8 + 8 + -8n = 64 + 8 Combine like terms: -8 + 8 = 0 0 + -8n = 64 + 8
Alright! I've seen quite a few of these so I thought I'd get them out of the way and help you out! :).
Direct variation is simple. The formula you'll use to find the constant K is as follows:
y = kx
Once you've established your formula you simply plug in:
.3 = (k)(.6)
Then you solve for k by dividing both sides by (.6) thus getting:
(.3/.6) = k OR (1/2) = k
Your direct variation equation is your standard formula with only K plugged in:
y = (1/2)x
2 tons per week would be 4000
100 pounds per hour would mean 16,800 and the difference would be 12,800
Answer:
20000
Step-by-step explanation:
To solve the problem, substitute the given points for x in the given equation to get
Solving the three equations simultaneously, we have:
a = -3, b = 2 and c = -5
Therefore, the required equation is
