Equation 1) 4x + 2y = 8
Equation 2) 16x - y = 14
Multiply all of equation 2 by 2.
2) 2(16x - y = 14)
2) 32x - 2y = 28
1) 4x + 2y = 8
Add equations together.
36x = 36
Divide both sides by 36.
x = 1
Plug in 1 for x in the first equation.
4x + 2y = 8
4(1) + 2y = 8
4 + 2y = 8
Subtract 4 from both sides.
2y = 8 - 4
2y = 4
Divide both sides by 2.
y = 4/2
y = 2
So, x = 1, y = 2

So, we’re looking for the amount of money Tom needs to spend to get his free meal.
X + 30.25 >
X > 9.75
X is the additional amount that Tom needs to spend. You subtract 30.25 on both sides in order to solve for x.
So, your answer would be at least $19.75
Answer:
The marginal error is 2.355
Confidence interval is 
The LB and UB are 34.645 and 39.3555 respectively.
Step-by-step explanation:
Consider the provided information.
n = 49, s = 8.2 c = 95%and 
Degree of freedom is: n-1 = 49-1 = 48.
From the table 
Marginal error is:
Hence, the marginal error is 2.355.
Part (B)
95% confidence interval estimate
Thus, the LB and UB are 34.645 and 39.3555 respectively.

3. Find the distance between -7 and 26
26-(-7) = 33
4. Divide the distance by 3
33/3 = 11
5. Find the distance from A---->B
-7 + 11 = 4
