Answer:
$1,365
Step-by-step explanation:
Large Pizza: 40*12= $480
Medium Pizza: 57*10= $570
Small Pizza: 35*9= $315
480+570+315= $1,365
Answer:
18/90=9/x and to find x use proportion so first 90*9=18x and 810=18x and x-45
Step-by-step explanation:
Step-by-step explanation:
2sin(x)cos(x) - sin(x) + 2cos(x)-1= 0
<=> sinx( 2cosx -1) + ( 2cosx -1) =0
<=> (sinx +1) + ( 2cosx-1)=0
<=> sinx=-1 or cosx= 1/2
+) sinx=1 => x= pi/2 + k×2pi
+)cosx=1/2 => x= pi/3+ k×2pi or x=-pi/3 + k×2pi
x€ [0,2pi] => x= pi/2, pi/3.
