       5p - 3q = -39
-     (-2p - 3q = 3)
==> 7p = -42 ==> p = -6

==> p = -6
      -2(-6) - 3q = 3 ==> 12 - 3q = 3 

==>p = -6
     -3q = 3 - 12 ==> -3q = -9

==> p = -6
       q = 3

Sveta_85 [38]

Answer:

50

Step-by-step explanation:

From the circle graph :

Salad sold :

Caesar = 70%

Garden = 16%

Taco = 14%

If 35 of the salad sold were Caesar ;

Then ; this means

70% = 35

Total salad sold %= (70+16+14)% = 100%

Let total sales = x

70% = 35

100% = x

Cross multiply :

70% * x = 100% * 35

0.7x = 35

x = 35 / 0.7

x = 50

Are sin and cos reciprocals of each other
sleet_krkn [62]
Hello,

When you compose 2 reciprocals functions, you will find 1.

ex f(x)=√x and g(x)=x² , x>=0
so that g(f(x))=(√x)²=x

sin(cos(0))=sin(1)=0,84147... rad and not 1.
Reciprocal function of sin (x) is arcsin(x).
Reciprocal function of cos (x) is arccos(x).
