The correct answer is option 2.
3 = 0
x - a = 0
x = a
x + b = 0
x = -b
We do not multiply any of these values by 3 because in a way, 3 is acting as another "zero" of the equation. Though, as shown above, it does not equal 0, it still does not apply to any of the other equations solved above.
Hope this helps!! :)
Answer:6.66666 kilocalories per hour
Step-by-step explanation:
Answer:
4x+3=2x+27
4x-2x=27-3
2x=24
x=24/2
x=12
C= 45 + 19.95h
45 for each home vist means one time payment
19.95 ever hour means you are charged 19.95 every hour
H= hour
Definitely Option A.
When you expand the bracket of Option A... You have your equation
Which is
-1/4x + 1/2.
