YOUR QUESTION:I have two questions!
We are currently learning about Literal Equations and Formulas and I was absent for the lesson. Thanks to the internet, a teacher and my textbook I managed to finish all the questions but two.
1. d. = f + fx
2. x - 4
____ = 5
y + 2
I can take pictures if needed.
And, if possible, could I get a breakdown of how to solve Literal Equations to make sure I'm set?
Is 1. d = f + fx ? Or is it 1.d. _ = f + fx? And what variable are you supposed to be solving for in each equation?
Solving literal equations involves simply isolating a variable. So, for example: d = f + fx
If you are supposed to be solving for x, then you need to isolate x (currently, d is isolated).
First, we'll take care of addition/subtraction because it's the simplest. f is added to fx (it's a positive; if it was negative, it'd be subtracted from fx) on the right side. In order to isolate x, we want to first "get rid" of f by subtracting it (the opposite of addition).
d = f + fx
-f = -f
d - f = fx
Now, we'll isolate x by dividing by f. x is multiplied by f, so we do the reverse (divide) to "get rid" of it.
d - f = fx
/f = /f
d/f - 1 = x
I know this is a bit late, so I hope it helps?

A common method I use is to take a word or phrase I like from the story and make that the title. You could also pull out the theme and use a thesaurus to find an appropriate word for the title. ^^

YOUR QUESTION: 'Explain how different wavelengths (colours) of light can affect the rate of photosynthesis. (3 marks)
I understand that chlorophyll reflects green light because it's green which means green light would make the rate of photosynthesis slow down but I'm not really sure how to explain it for other colours? Thanks for any help!
These links may help?

Ahh, this may seem like the easiest question you can find but, help me...
The answer key says 54*3, could anyone explain?
The key here is that you're dealing with equilateral triangles, which means that the length of all three sides is equal to each other.
Now, you know that if you line all the triangles up in a straight line, that equals 54 cm. Triangles have three sides and since only the triangles are shaded, to find the perimeter, you simply multiply 54 cm by 3.
Think about it like this: the triangles are all currently on side 1. To find the perimeter, you could flip the triangles to side 2 and measure that line. Since these are equilateral triangles, this line will also be 54 cm. Finally, you would flip the triangles over to side 3 and measure that line. Again, these are equilateral triangles, so this will also be 54 cm. So your perimeter is 54 cm + 54 cm + 54 cm OR 54 cm * 3.
Hope that helps!
