Answer:
407
Step-by-step explanation:
Given :
Thursday Friday
School play 300 x
Band concert 184 250
To Find : value of x
Solution
Since we are given that there is an association
So,
Thus the value of x is 407
6 pack for $3.79
- Divide 6 by 3.79
- 6/3.79 = 1.58
- This pack is $1.58 per bottle
9 pack for $4.50
- Divide 9 by 4.50
- 9/4.50 = 2
- This pack is $2.00 per bottle
12 pack for $6.89
- Divide 12 by 6.89
- 12/6.89 = 1.74
- This pack is $1.74 per bottle
The pack of 6-pack of bottled water for $3.79 costs the least per bottle ($1.58).
Answer:
Step-by-step explanation:
If a complex number is z=a+ib, then the trigonometric form of complex number is
where, and , is called the argument of z, .
The given complex number is -5i.
It can be rewritten as
Here, a=0 and b=-5. lies in 4th quadrant.
So, the trigonometric form is
(0,2),(-2,-1),(2,5)
-3x+2y=2
+3x +3x
2y/2=3x+2/2
y=1 1/2x+2
Plug in numbers for x then solve for y
