Answer:
no soution
Step-by-step explanation:
3x - 2x + 4 = 5x - 4x - 8
Combine like terms
x+4 = x-8
Subtract x from each side
x+4-x =x-x-8
4 = -8
This is never true so there is no solution
The answer is 25/3 or in decimal 8.333333
secx=1/cosx
1. To solve this problem you must apply the following proccedure:
2. You have to verify if secx sinx=tanx, so, you have:
3. You know that secx=1/cosx, and tanx=sinx/cosx, therefore:
(secx)(sinx)
(1/cosx)(sinx)
sinx/cosx
tanx
Answer:
360 = x + 30
x = 390 meters
Step-by-step explanation:
Is means equal to and of means multiply. So....your equation would be 12=60%x. Now since u can't multiply by a percent, u gotta do 12=.6x. Now divide by .6 so that it cancels out. Your answer is 20. Hope this helps!
