23 + 36 = 59
I hope this helps. Brainliest appreciated.
For this case we have the following system of equations:

We multiply the first equation by -5:

Thus, we have the equivalent system:

We add the equations:

We find the value of the variable "x":

Thus, the solution of the system is:

Answer:

Answer:

Step-by-step explanation:
Height of the triangle:
10cos(30) = 5sqrt(3)
Radius = ⅓(5sqrt(3)) = 5sqrt(3)/3
Triangle - circle
[½(10)(10)sin60] - [(3.14)(5sqrt(3)/3)²]
43.30127019 - 4.166667
39.13460352 unitsw
Answer:
The lowest price per once is: "Don's store" $ 0.101
Step-by-step explanation:
You have to apply a 3 way rule
so:
1) 60 oz ----- $6.50
1 oz ----- =(1 oz X $6.50)/ 60
= $0.108
2) 54 oz ----- $5.50
1 oz ----- =(1 oz X $5.50)/ 54
= $0.101
3) 48 oz ----- $5.61
1 oz ----- =(1 oz X $5.61)/ 48
= $0.116
4) 40 oz ----- $4.50
1 oz ----- =(1 oz X $4.50)/ 40
= $0.112
