measurement from your hotel to the museum is 3.25
inches. What is the actual distance?
A. 26 miles
B. 3.8 miles
C. 32.5 miles
D. 38 miles
Answers
Answer:
A
Step-by-step explanation:
The system of equations below has exactly one (x, y) pair for its solution.
4x+6y=244x+6y=24
2x+y=82x+y=8
If we double each side of the second equation, 2x+y=82x+y=8, we have 4x+2y=164x+2y=16. Explain why the same pair that is the solution to the system is also a solution to this new equation.
If needed, you can support your explanation with hanger diagrams (upload a picture), or by inventing a situation that the equations represent.
If we add the two equations in the original system, we have 6x+7y=326x+7y=32. Explain why the same (x, y) pair is also a solution to this equation.
Again, you can support your explanation with diagrams or a situation, if needed.

Solve for z:
14=z-(-12)
z=___
Answers
Answer:
z=2
Step-by-step explanation:
14=z+12
2=z
Answer: The answer is z=2.
Step-by-step explanation: Step 1. Simplify the both sides of the equation: [tex]14=z+12[/tex].
Step 2. I flipped the equation that looks like this: [tex]z+12=14[/tex].
Last but not least is step 3. Subtract 12 from the both sides: [tex]z+12-12=14-12[/tex]; ∴, your answer should be z=2, I hoped this helps, Happy New Year, and mark me as brainliest. :D

The function y = 2x + 8 represents the cost y (in dollars) of a large pizza with x toppings, where x
is equal to 0, 1, 2, or 3.
Identify the independent and dependent variables, the domain, and the range.
Answers
Answer:
0 ,1,2,3,/ is range/ y is the independent varibal/ x is the dependent varible/ /the equation is the domain
Step-by-step explanation:
The domain and independent variables are 0, 1, 2, and 3.
The range and dependent variables are 8, 10, 12, and 14.
What is a function?A function is defined as a relation between a set of inputs having one output each.
Inputs are called the domain and independent variables.
Outputs are called the range and dependent variables.
We have,
y = 2x + 8
y = cost of pizza in dollar
x = toppings on pizza
x = 0, 1, 2, or 3
y = 2 x 0 + 8 = 8
y = 2 x 1 + 8 = 2 + 8 = 10
y = 2 x 2 + 8 = 4 + 8 = 12
y = 2 x 3 + 8 = 6 + 8 = 14
Thus,
The domain and independent variables are 0, 1, 2, and 3.
The range and dependent variables are 8, 10, 12, and 14.

Can someone help my sis on these questions? I dont remember how to do these things (part 1)
Answers
Answer:
Read below for each answer! (^-^)
Step-by-step explanation:
1: You got the first one right. The explanation does explain why but think about 0 as the surface of the water to better understand.
2: -3; it is between 2 and 4 with only one line through it meaning that it is -3.
3: 7. That's the greatest number both can divide into it.
4: The last one. Any positive number is greater than a negative one and peanut butter's freezing point is positive while the other one's is not.
5: You got it right again! -(-1) has two negatives. Two negatives (mostly) make a positive. So positive 1! Now describe that on a number line.
Hope this helps!

Given that the equation y=mx + b where m is 12 and the line passes through the point (-2,8), what would be the value of b?
a. b = -16
b. b = -8
c. b = 16
d. b = 32
Answers
Answer:
d
Step-by-step explanation:
The answer would be D. We can continue the line from the point (-2,8) because we know the slope so we will continue it forward by two on the x axis. Since we go forward by two we are going up by 24 (12*2) on the y axis so the y intercept (b) would be 8 + 24 which is 32. Sorry if it is hard to understand.
