If 64 is 4 times the difference between sarah's age and 44, then '64/4' would be the difference between sarah's ages and 44.
difference=64/4=16
The difference between Sarah's age and 44 is 16.
So Sarah is either '44+16' years old, or '44-16' years old
a=44+16=60 years old
a=44-16=28 years old
Since the problem says Sarah is older than 44, she must be 60 years old
Answer:
60 yrs old

The corresponding roots of the quadratic equations are given.
What are Quadratic Equations?
Quadratic expressions are polynomial equations of second degree.
The general form of a quadratic equation is ax² + b x + c = 0.
1. x² = 49
Find the square root.
x = ±√49 = ±7
2. x² - 27 = 0
x² = 27 = 9 × 3
x = √27 = √(9×3) = √9 × √3 = ±3√3
3. 3x² - 36 = 0
3x² = 36
Divide 3 on both sides.
x² = 12
x = √12 = √(4 × 3) = ±2√3
4. 9x² = 0
x = 0
5. 5x² - 15 = 0
5x² = 15
x² = 3
x = ±√3
6. 2x² - 144 = 0
2x² = 144
x² = 72
x = √72 = √(36 × 2) = ±6√2
7. (x + 3)² = 9
x + 3 = √9
x + 3 = ±3
x = 3 - 3 = 0 and x = -3 - 3 = -6
8. 4x² - 100 = 0
4x² = 100
x² = 25
x = ±√5
9. 5x² = 40
x² = 8
x = √8 = √(4 × 2) = ±2√2
10. 3x² - 12 = 0
3x² = 12
x² = 4
x = ±2
11. (x - 5)² = 121
x - 5 = √121
x - 5 = ±11
x = 11 + 5 = 16 or x = -11 + 5 = -6
Hence the solutions are found.

Answer:
Hot dogs sold: 44
Sodas sold: 132
Step-by-step explanation:
This is is a problem of a system of two equations with two unknowns. This can be solved in multiple ways (the substitution method, the elimination method, the equalization method, the graphic method...) . I will resolve it using the equalization method that is a little bit more practical from my point of view.
First, we have to determine the system by the data we are given:
Where:
Secondly, we are going to isolate any variable from both equations. I chose to isolate Y.
Thirdly, we equalizate both equations.
So we get:
Then we isolate X.
So now we know that the number of hot dogs sold was 44! If the sodas sold were three times the number of hot dogs sold, then we know that there were 132 sodas sold at the hockey game!
