I’m really sorry. I really try to figure this out but I’m Real bummed out that I can’t even get this. What even is this question? Like tell me the answer if you can even find out ._.
Four tenths is expressed as .4
five thousandths is expressed as .005
the sum of these is .405 and divided by 2 (there are two numbers we added), we get .2025, that is the average
For this case, the first thing we must do is define a variable.
We have then:
x: number of weeks
y: amount of cereal that Melanie eats
We now write the function that models the problem:

Then, for 5 weeks we have:
Answer:
A model that best represents the number of pounds of cereal she eats is:
For 5 weeks we have:
X^2 - 5x - 8 - <span>2x^2 + 4x + 3
= -x^2 - x - 5

Answer:
x = 95°
y = 147°
z = 128°
Step-by-step explanation:
∡x is the sum of 50 and 45, deducted from 180
∡y = 95 + 52, deducted from 180
∡z = 180 - 52
