Answer:
Step-by-step explanation:
Let s and h represent the numbers of sodas and hotdogs sold, respectively. The problem statement tells you ...
... s + h = 165
... s - h = 39
Add these two equations to get ...
... 2s = 204
... s = 102 . . . . . divide by w
... h = 165 - 102 = 63 . . . . use the first equation to find h from s
The vendor sold 102 sodas and 63 hot dogs at the basketball game.
The answer would be $11.8 then just round that up to the nearest whole number which would be $12. Hope this helped if I’m incorrect I apologize:/but I’m pretty sure that’s right!
A triangle equals 180 degrees, so we already have the other which total to 152. So we just have to 180‐152, and the answer is 28.
Option A:
All of Jaiden's work is correct. The solution is x = 31.
Solution:
Given equation is 3x – 8 = 2x + 23.
Step 1: 3x – 8 = 2x + 23
Subtract 2x on both side of the equation, we get
⇒ 3x – 8 – 2x = 2x + 23 – 2x
⇒ x – 8 = 23
Step 2: x – 8 = 23
Add 8 on both sides of the equation.
x – 8 + 8 = 23 + 8
x = 31
Step 3: x = 31
The solution is x = 31.
Option A is the correct answer.
So, all of Jaiden's work is correct. The solution is x = 31.
Answer:
2π ≈ 6.283
Step-by-step explanation:
The average value of the function is the area under it, divided by the base. This function describes a semicircle of radius 8, so its area is ...
A = 1/2πr² = 1/2π·8² = 32π
The width of the base is the diameter of the semicircle, so is 16. Then the average value is ...
32π/16 = 2π . . . . . average value of y
