400 - 3x = 163
Add 3x to both sides.
400 = 163 + 3x
Subtract 163 to both sides.
237 = 3x
237/3 = 79
Answer:


Science class had a higher average
Step-by-step explanation:
Given

g(x) table
Solving (a): f(2)
We have:

So:



Solving (b): g(2)
From the given table.

Solving (c): f(4) or g(4); which is greater

So:



For g(4): Notice that in the table of g(x); g(x) increases by 2 when x increases by 1
This means that:

So




<em>Hence, g(4) i.e. Science class is greater</em>
Click off the first one because 180 (Thea) < 225 (Eleanor). Then keep the second one and click the third and fourth one.
This is because of there different marketing statargies plus the reason behind this can be because they have high stock left and they want to clear that
Sum means add, a number means x, and four means, uh, 4...
x+4. is what you're looking for
