The answer i got was x=2 :)
Step 1: Simplify both sides of the equation.
x−2 over 3−(x+3 over 5)=−1
Simplify: (Show steps)
2 over 15x+−19 over 15=−1
Step 2: Add 19/15 to both sides.
2 over 15x+−19 over 15+19 over 15=−1+19 over 15
2 over 15x=4 over 15
Step 3: Multiply both sides by 15/2.
(15 over 2)*(2 over 15x)=(15 over 2)*(4 over 15)
F(1)=8000x0.55x1=4400
f(2)=8000x0.55x2=8800
(8800-4400)/2=2200
Answer:
see explanation
Step-by-step explanation:
Using the sum to product identity
cosx + cosy = 2cos(
)cos(
)
Consider left side
(cos5A +cos3A) + (cos15A + cos7A)
= 2cos(
)cos(
) + 2cos(
) cos(
)
= 2cos(
) cos(
) + 2cos(
)cos(
)
= 2cos4AcosA + 2cos11A cos4A ← factor out 2cos4A from both terms
= 2cos4A( cos11A + cosA) ← repeat the process
= 2cos4A( 2cos(
)cos(
)
= 2cos4A(2cos(
)cos(
)
= 2cos4A(2cos6A cos5A)
= 4cos4Acos5Acos6A
= right side , thus verified
The answer is y+4=x thats the answer on E d g e n u i t y
Given :
Insurance cost , $693.00 .
Gas cost , $452.00 .
Average charge per fare , $7.00 .
Tuition fee , $3280.00 .
To Find :
The fare he have to get to pay his fee .
Solution :
Let , number of fair required is n .
Therefore , total profit is :

Now , to pay his fee this profit must be equal to his fee because he don't have other expenditure .
So ,

But number of rides cannot be in decimal so minimum rides he must get is
632+1 = 633 .
Hence, this is the required solution .
