Answer:
A
Step-by-step explanation:
We can substract the wavength of the violet light to the wavelength of the red light:
(6.5 x 10^-7 m) - (4.0 x 10^-7 m) = 2.5 x 10^-7 m
<span>4x+5/6x^2-x-12 - (5x/6x^2-x-12)
= (4x + 5 - 5x)/(</span>6x^2-x-12)
= (-x + 5) / (2x - 3)(3x +4)
<span>
answer
-x + 5
---------------------
</span> (2x - 3)(3x +4)
Answer:
Alex has 1 cake
Step-by-step explanation:
I mean pretty simple subtraction here, it's 4-3=1. That's finger math dude
We have:
5(x + 7) = 85 |divide both sides by 5
x + 7 = 17 |subtract 7 from both sides
x = 10
Whole number can be a integer. rational number can not be a integer that is repeating.
