1) Debbie has $93 saved up to buy a PS4 on Black Friday. On Black Friday the PS4 will cost $150 dollars, if Debbie babysits and earn two dollars everyday she babysits, how many days left does she have until she can buy the PS4?
2n+93=150
2n=150-93
2n=57
n=
2) What does P equal? P stands for the amount of apples needed for a pie sale. We also need to find Q, which is how much peaches we'll need as well, because it is a peach and apple pie sale.
-----------------------------------------
pq=7*10
pq=70
Hope this helps, have a BLESSED and wonderful day! :-)

Answer:
Step-by-step explanation:
You can start by recognizing 19/12π = π +7/12π, so the desired sine is ...
sin(19/12π) = -sin(7/12π) = -(sin(3/12π +4/12π)) = -sin(π/4 +π/3)
-sin(π/4 +π/3) = -sin(π/4)cos(π/3) -cos(π/4)sin(π/3)
Of course, you know that ...
sin(π/4) = cos(π/4) = (√2)/2
cos(π/3) = 1/2
sin(π/3) = (√3)/2
So, the desired value is ...
sin(19π/12) = -(√2)/2×1/2 -(√2)/2×(√3/2) = -(√2)/4×(1 +√3)
Comparing this form to the desired answer form, we see ...
A = 2
B = 3
- y= -3x+4
- y-4=-3x
- x= <u>y-4</u>
- <u> </u><u> </u><u> </u><u> </u><u> </u><u> </u>-3
hope it helps
