Integers are those numbers that can be represented positively or negatively.
Integers are never in decimal numbers.
Integers are whole numbers with positive signs and negative signs.
Below zero degrees means the temperature is in negative value.
The integer that represents the wind chill temperature is -25°F.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
Integers are those numbers that can be represented positively or negatively.
Integers are never in decimal numbers.
Integers are whole numbers with positive signs and negative signs.
Temperature outside = 5°F
The wind is blowing 15 miles an hour.
The wind chill makes it feel like the temperature is 25°F below zero.
Below zero degrees means the temperature is in negative value.
This can be represented by an integer as,
= -25°F
Thus,
The integer that represents the wind chill temperature is -25°F.

Ben and josh went to the roof of their 40-foot tall high school
Mr. Dudley is writing a test for his mathematics class. The test will have true/false
questions worth 2 points each and multiple-choice questions worth 4 points each for a
total of 100 points. He wants to have twice as many multiple-choice questions as
true/false questions. How many true/false questions and multiple-choice questions will
be on the test?
Answer:
10
Step-by-step explanation:
so x=true/false questions
y=multiple-choice questions
2x+4y=100
2x=y
plug in 2x for y in the first equation
2x+4(2x)=100
10x=100
x=10
y=20
The total questions would include 10 true/false questions and 20 multiple-choice questions.
We have Mr. Dudley who is writing a test for his mathematics class. The test will have true/false questions worth 2 points each and multiple-choice questions worth 4 points each for a total of 100 points. He wants to have twice as many multiple-choice questions as true/false questions.
We have to determine how many true/false questions and multiple-choice questions will be on the test.
What do understand by Modelling of a Equation ?The modelling of equation is done to derive a mathematical relation among the terms defined in a mathematical statement.
According to the question -
Assume that the number of true/false questions be x.
Assume that the number of multiple-choice questions be y.
Then -
y = 2x
Points for each true/false questions - 2 points
Points for each multiple-choice questions - 4 points
Total points of test = 100 points
Now,
Model the equation on the basis of above information -
2x + 4y = 100
2x + 4 (2x) = 100
2x + 8x = 100
10x = 100
x = 10
Therefore -
y = 2x = 2 x 10 = 20
Hence, the total questions would include 10 true/false questions and 20 multiple-choice questions.

That is the question simplified. The part that you need to do from here is to figure out what x is. A way you can do that is by plugging in different solutions of what x could be until you find a solution that fits into the equation. I can't help that much but I hope that my solution helps.
This table shows a linear relationship. x 5 6 7 8 9 y 33 39 45 51 57 Based on the information in this table, which equation can be used to model the relationship between x and y? A y = 3x + 6 B y = 6x + 3 C y = 3x D y = 6x
Answer:
B. y = 6x + 3Step-by-step explanation:
Given
x = {5, 6, 7, 8, 9} andy = {33, 39, 45, 51, 57}The equation in slope- intercept form:
y = mx + bUsing two pairs of coordinates (5, 33), (6, 39), we will find the slope:
m = (39 - 33)/(6 - 5) = 6/1 = 6Using one point (5, 33) to find the y-intercept:
33 = 6*5 + b ⇒ b = 33 - 30 ⇒ b = 3The equation is:
y = 6x + 3Correct option is B
raise the product of 36 and 9 to the power of the sum of 2 and 4
Answer:
1.15683 1381 * 10^15
Step-by-step explanation:
To get the answer, first, get the product of 36 and 9
This can be obtained by multiplying 36 with 9
36 * 9 = 324
We then raise 324 to the power of the sum of 2 and 4
The sum of 2 and 4 is gotten by adding 2 to 4
So,
2 + 4=6
Therefore, 324 raised to the power of 6
= 1.15683 1381 * 10^15
