Answers
Answer: The temperature change of the water
The most important data that the student would have to record for the investigation that he is carrying out is temperature.
What is temperature?This is the term that is used to refer to the degree of hotness or the degree of coldness of a given body.
The temperature is the solution here because the factor that the student is set to find out would be how heat is able to transfer to water.
The variable that would be used to represent heat is going to be temperature. This is what would help to determine the amount of heat that has transferred.
This can be checked with the use of a thermometer. The investigation that the student is carrying out here would be what is called a research study.
Heat is one of the variables that is used in the research study. Therefore we can conclude by saying that the most important data that is going to be used in this research would be what is called temperature.

Answer:
x = -6
Step-by-step explanation:
Distribute the 2 into the brackets:

2x = -2 -10
2x = -12
divide both sides by 2:
x = -6

John went to an electronics store to purchase a new computer. The electronics store allowed John to make payments on the computer instead of paying the entire amount upfront. If John decides to purchase a computer that costs $1,260, and he makes 6 equal monthly payments, what would be his monthly payment?
Answers
Answer:
The monthly payment is $210
Step-by-step explanation:
The computation of the monthly payment is shown below:
Given that
The cost of the computer i.e. purchased is $1,260
And, there are 6 equal monthly payments
So, the monthly payment is
= Computer cost ÷ number of equal monthly payments made
= $1,260 ÷ 6 payments
= 210
hence, the monthly payment is $210 and the same is to be considered

Evaluate the following expression when a = -3, b = 2, c = 5, and
d = -4.
2a + 3b
Answers
Answer:
2a + 3b = 0
Step-by-step explanation:
So we are given that a = -3, b = 2, c = 5, and d = -4 and we are asked to evaluate the expression 2a + 3b. To evaluate the expression, we would have to plug in -3 for a, 2 for b, 5 for c, and -4 for d:
2a + 3b = 2(-3) + 3(2) = -6 + 6 = 0
So by evaluating the expression we get 0.

The following statement is an example of: every fall there have been hurricanes in the tropics. Therefore, there will be hurricanes in the tropics this coming fall.
Is it deductive, indutive reasoning or a conjecture.
Answers
Answer:
Deductive reasoning
Step-by-step explanation:
Here, we want to know the kind of reasoning the statement is.
In this question, the kind of reasoning is deductive
In the deductive reasoning type, we go from general cases to specific cases
It is just like saying the reason why there will be hurricanes in the tropics this fall is because there is an hurricane every fall
So we have gone from a general case to give a specific case
The kind of reasoning which is depicted by the statement given above is deductive reasoning.
From the statement, we are moving from a general perspective, which is the fact that, hurricane occurs every fall in the tropics. Using these general precedence, we deduce that the same event will occur again. We are basing a reasoning on a general fact, hence, the reasoning is deductive.Therefore, the reasoning in the scenario above is deductive.

False
Step-by-step explanation:
5x - 4 versus 2x + 26
Imagine x equals 1, then the equations would be:
5(1) - 4 and 2(1) + 26
1 and 28 are not equivalent.
Another example would be x = 6
5(6) - 4 and 2(6) + 26
26 and 38 are not equivalent.
No matter what you replace x with, the expressions are never equal.

given the parallel lines cut by. a transversal , determine the value of x . please help due in 30 minutes
Answers
Answer:
x = 20
Step-by-step explanation:
The angles are same side interior angles so the add to 180
3x-10 + 5x+30 = 180
Combine like terms
8x +20 =180
Subtract 20 from each side
8x+20 -20 =180-20
8x = 160
Divide by 8
8x/8 =160/8
x = 20
Answer: x = 25
Step-by-step explanation:
When lines are parallel, the same side interior angles are supplementary, meaning they add up to 180 degrees. So to find x, you would add the two expressions and make it equal to 180 degrees.
3x - 10 + 5x + 30 = 180
8x - 20 = 180
8x = 200
x = 25
The answer is x=25
