Henry runs up 10.5 flights of stairs. To represent an additive inverse, Henry will have to run down flights of stairs
Answer:
The additive inverse would be -10.5
Henry runs up 10.5 flights of stairs. Then the additive inverse represents running down flights of stairs will be - 10.5.
What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
PEMDAS rule means the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.
The reverse number is a number's complementary inverse. When a number is multiplied by its additive inverse, the result is zero.

Answer:
Option B
Step-by-step explanation:
In order to find the answer to this question you need to use KCF and solve. Remember that negative times a positive equals a negative.
[tex]-\frac{3}{4} \div\frac{2}{8}[/tex]
Use KCF
[tex]-\frac{3}{4} \times\frac{8}{2}[/tex]
Multiply:
[tex]3 \times 8 =24[/tex]
[tex]4\times2=8[/tex]
Remember that negative times a positive equals a negative:

The situation shows neither correlation nor causation
Answer:
The correct option is;
The situation shows correlation without causation
Step-by-step explanation:
The given data are;
Weight y [tex]{}[/tex] Miles Per Gallon
42 [tex]{}[/tex] 18
36 [tex]{}[/tex] 12
30 [tex]{}[/tex] 6
. [tex]{}[/tex] x
24 [tex]{}[/tex] 0
The first difference of the data = 42 - 36 = 36 - 30 = 30 - 24 = 6
18 - 12 = 12 - 6 = 6 - 0 = 6
The first difference of the data is constant and equal to 6
Therefore, the graph is a straight line graph with y-intercept = 24 and slope given by the rate of change of the weight to the miles per gallon of fuel consumption as follows;
The rate of change of the weight to the miles per gallon of fuel consumption is given as follows;
(42 - 24)/(18 - 0) = 1
Therefore, the points of the data fit into the straight line and the data of the situation shows correlation
In order to show causation, and to rule out other possible causes for the rise in MPG, a separate experiment will be required whereby the cause for the rise in MPG can be determined.
Answer:
The situation shows correlation with causation.
Step-by-step explanation:
A correlation between two variables is a measure of the strength of the association between them.
It can be seen from the scatter plot that as the weight of the car increases, the miles per gallon decreases.
Causation between variables indicates that one of the variables causes the other variable to occur. Causation between variables always implies correlation.
The weight of the car affects the miles per gallon because cars that weigh more require more power to move. Hence, heavier cars get lower miles per gallon of fuel.
Therefore, the situation shows correlation with causation.

Rita goes for a bike ride on a trail by her house. After 15 minutes of riding she sees a mile marker. When she reaches the third mile marker, she realizes that she has been biking for 30 minutes. What is the rate at which she is riding?
Given:
Rita covered 1 mile in 15 minutes.
She covered 3 miles in 30 minutes.
To find:
The rate at which she is riding.
Solution:
Let y be the number of miles covered in x minutes.
Rita covered 1 mile in 15 minutes. So, the point is (15,1).
She covered 3 miles in 30 minutes. So, the point is (30,3).
Slope of the line:
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\dfrac{3-1}{30-15}[/tex]
[tex]m=\dfrac{2}{15}[/tex]
Therefore, she is riding [tex]\dfrac{2}{15}[/tex] miles per minute.

Answer:
C.
Step-by-step explanation:
f(x) = 3x+2
f(x) = -4
-4 = 3x+2
-4-2 = 3x
-6 = 3x
-6/3 = x
-2 = x
x = -2
Solve using fraction strips or common denominators:
1/2 + 3/10=
Answer:
4/5 (or 8/10)
Step-by-step explanation:
the least common denominator of 2 and 10 is 10, so you have to multiply the first fraction (1/2) by 5/5 so that the denominator of that fraction will become 10. Since 3/10 already has 10 as the denominator, you leave it. By adding 5/10 and 3/10 together you'll get 8/10.
If the question asks to simplify your answer, divide the numerator and denominator of 8/10 to get 4/5
