Let the hamburgers be x and cheese burgers be y.
x + y = 24
3x + 3.5 y = 79
x = 24 - y.
Substituting the value of x,
3( 24 - y) + 3.5 y = 79
72- 3y + 3.5 y = 79
72 + 0.5 y = 79
0.5y = 79 - 72 = 7
1/2 y = 7
thus, y = 7 * 2 = 14
Substituting the value for x,
x + y = 24
x + 14 = 24
x = 24-14 = 10
Thus, x = 10.
Thus, she sold 10 hamburgers and 14 cheeseburgers

The true statement about Sam’s conjecture is that the conjecture is not correct
<h3>How to determine if Sam’s conjecture is correct or not?</h3>
Sam’s conjecture is given as:
For x ≤ - 2
It is true that x^5 + 7 > x^3.
The inequality x ≤ - 2 means that the highest value of x is -2
Assume the value of x is -2, then we have:
(-2)^5 + 7 > (-2)^3
Evaluate the exponents
-32 + 7 > -8
Evaluate the sum
-25 > -8
The above inequality is false because -8 is greater than -25 i.e. -8 > -25 or -25 < -8
Hence, the true statement about Sam’s conjecture is that the conjecture is not correct

Hi
Yes 54 is a rational number because it can expressed as the quotient of two integers : 51 divide by 1
I hope that's help :)
Answer: 
Step-by-step explanation:
For finding the quotient of the given division,
In the long division method, we will follow the following steps.
Step 1 : Here the divisor is d-2 and dividend is 
Multiply (d-2) by 
and subtract the dividend by the resultant.
We get 
Step 2: Multiply (d-2) by 
and subtract the remaining dividend by the resultant.
We get 
Step 3 : Multiply (d-2) by 
and subtract the remaining dividend by the resultant.
We get 
Since, after getting 7 it is not possible further division,
Hence, Remainder = 7,
Quotient = sum of all expression by that we multiply (d-2) =
