Answer:
x = - 3
Step-by-step explanation:
1 + x - 1 + 12x = 12x - 3
Subtract 12x from both sides.
1 + x - 1 = - 3
Combine like terms on the left side.
x = - 3
69699696969699696969969696969969699696969969696996969696
To solve this we would do 30×365
We would do this because each day the dog 30lbs
So we have the equation y=30x
Where y= total amount of dog food
And x= number of days
In a year there are 365 days typically, so we do 30×365
30×365=10,950
In one year 10,950 lbs of dog food are used
Answer:
tanA/2.
Step-by-step explanation:
some trigonometric properties:
* tanA = sinA/cosA
* secA = 1/cosA
* cscA = 1/sinA
* cotA = cosA/sinA
1/sinA - cotA
1/sinA - cosA/sinA
1 - cosA / sinA
.... 1 - cosR / sinR = tan(R/2)
1 - cosA / sinA
= tanA/2.
