Answer:
See below
Step-by-step explanation:
The total cost depends on:
1. Software cost
2. each yearbook cost
<u>Variables:</u>
Let the total cost be (y) and the cost of each yearbook be (x).
To print x yearbooks, it's going to cost 15x
Also, there is software (fixed cost) cost of 800
So total cost would be:
y = 800 + 15x
Answer:
Area = 113.04 m²
Step-by-step explanation:
Area of a circle:
If we are told to use 3.14 for pi we can now make a new equation:
Area = 3.14×6²
Area = 3.14×36
Area = 113.04m²
What do we know about these angles? Immediately, you might notice that (4y-8)° and (16x-4)° share a line. The same is true of (16x-4)° and (14x+4)°. Any straight line forms what's called a <em>straight angle</em>, which measures 180°, so we know that, since they add up to form a straight angle, (14x+4)° and (16x-4)° must add up to 180°. We can use that fact to set up an equation to solve for x:
(14x+4)+(16x-4)=180
After you solve for x, you should look to solve for y. How can we figure out what y is? If you're familiar with the vertical angle theorem, you'll know that all vertical angles (angles that are directly across from each other diagonally) are equal. So we know that 14x+4=4y-8. You can use the value of x you solved for before to solve this one fairly easily, and then you'll have both values.
