I would use a proportion for the Fred's Fouls part. Use the closest point to 12 possible, which is (15, 69.5).
Set up the proportion like so:
15/69.5 = 12/x
Now cross multiply.
15x = 834
Now divide both sides by 15 to get x by itself.
x = 55.6
Fred's Fouls will charge $55.60 for 12 wings.
Now plug in 12 as x for the Carlie's Chicken part and solve for f(12).
f(12) = 3.75(12) +10
f(12) = 45 +10
f(12) = 55
Carlie's Chicken will charge $55 for 12 wings.
<span>Simplify 8 - {x - (5 + x)}:
Order of operations rules require that you perform work inside parentheses first. Thus, do this first: </span>x - (5 + x) => x - 5 - x => -5.
Now we have the following: 8 - {-5} => 8+5 = 13 (answer)
Please note: To avoid confusion, please separate answer choices, such as <span>3 13 -2x + 3 -2x + 13, by using commas or by putting each choice on its own new line:
</span><span>3
13
-2x + 13
I was and still am unsure of what you meant here.</span>
Answer:
x = 17
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides , that is
x² = 15² + 8² = 225 + 64 = 289 ( take square root of both sides )
x = 
= 17
3. <u>Two angles and included side (ASA congruence theorem)</u>.
<u>Reason:</u> This is because, it is given that angle Q is congruent to angle T and line QR is congruent to line TR. Also, we proved in step 2 that 
. Thus, we have two angles and the side included as congruent and thus, the two triangles are congruent.
4. <u>CSCT (Corresponding Sides of a Congruent Triangle)</u>
<u>Reason:</u> PR and SR are the corresponding sides of the congruent triangles 
and 
, therefore, by the CSCT these corresponding sides have to be congruent.
