Answer:
p = 14
Step-by-step explanation:
6 = p - 8
We want to isolate p, so add 8 to both sides.
6 + 8 = p
Add.
14 = p
Hope this helps!
Answer is: P = 14
Switch up the numbers.
6 = p - 8 → 6 + 8 = P
Solve for P.
6 + 8 = 14
Hence, 14 is the answer.

Answer:
Option 2 is better than option 1.
Step-by-step explanation:
Option 1:
She can receive a salary of $600 per week (this is constant)
Option 2:
She will receive $350 per week plus 8% of her weekly sales.
Let the weekly salary be represented by = x
8% commission means she will earn
Now given is : If Chloe has $3,200 in weekly sales,
then through option A, she will earn $600.
And through option B she will earn:
Hence, option 2 will help Chloe earn more.
Part B:
Part C:
Option 1 will lead to a greater earn when

again, we're assuming that both triangles are similar, and thus using proportions.
we do not use the -10, because whatever value "x" may be, can't be negative or even 0.

Step-by-step explanation:
To find the value of sin 450 degrees using the unit circle, represent 450° in the form (1 × 360°) + 90° [∵ 450°>360°] ∵ sine is a periodic function, sin 450° = sin 90°.
Rotate ‘r’ anticlockwise to form a 90° or 450° angle with the positive x-axis.
The sin of 450 degrees equals the y-coordinate(1) of the point of intersection (0, 1) of unit circle and r.
Hence the value of sin 450° = y = 1
