Convert the mixed numbers to improper fractions:
[tex]\implies \dfrac{12 \times 3+2}{3} \times \dfrac{19 \times 4+1}{4}[/tex]
[tex]\implies \dfrac{36+2}{3} \times \dfrac{76+1}{4}[/tex]
[tex]\implies \dfrac{38}{3} \times \dfrac{77}{4}[/tex]
[tex]\textsf{Apply the fraction rule} \quad \dfrac{a}{c}\times\dfrac{b}{d}=\dfrac{ab}{cd}:[/tex]
[tex]\implies \dfrac{38\times77}{3\times4}[/tex]
[tex]\implies \dfrac{2926}{12}[/tex]
Divide the numerator and denominator by 2:
[tex]\implies \dfrac{2926 \div 2}{12 \div 2}[/tex]
[tex]\implies \dfrac{1463}{6}[/tex]
Convert to a mixed number:

Use the rate and the amount of water pumped after 13 minutes to find how much will have been pumped into pool after 14.5 minutes? The unit rate is 24 gal/min so 1.5 minutes after 13 minutes, an additional gallons will be pumped in
An additional 36 gallons of water will be pumped into the pool past 13 minutes
Constant rate of flow: The definition of a constant rate of flow rate shows how fluid of a certain volume moves through a segment in a specified amount of time. Instead of measuring how quickly a fluid moves from point A to point B, the motion of fluids is examined by figuring out its flow rate. Specifically, how much fluid volume moves from point A to point B in a given amount of time.
Time for which water has been pumped into the pool = 13 minutes
Rate of flow of water = 24 gal/min
So, water pumped in 1.5 minutes = 24*1.5 = 36 gallons
Total water pumped in the pool in 14.5 minutes = 24*14.5 = 348 gallons

Need help for solving fox x
-6 is the value of X
The question can be answered by simply following the rules of angles of geometry. The rule that follows here is:
Rule: Vertically opposite angles are equal i.e whenever two straight lines cross, they create two pairs of equal vertically opposite angles.
Because, both the angles given in the question are vertically opposite to each other
Therefore, angle 80 degree = angle 86 + X
i.e 80 = 86 + X
--> 80 - 86 = X
--> -6 = X

The inequalities in interval notation are given below
What is an inequality?
An inequality in maths is a relationship that makes a non-equal distinction between two values as well as other mathematical expressions. It is most frequently used to compare the sizes of two digits on a number line. There are multiple formulae used to denote various types of inequalities:
(i) The symbol a < b indicates that a is less than b.
(ii) a > b indicates that a is bigger than b.
In either scenario, a and b are not equivalent. These are characterized as tight inequalities because a is either strictly less than or strictly bigger than b. Equivalence is not permitted. In contrary to rigorous inequalities, there are two forms of non-strict inequality relationships.
The inequalities in interval notation are given below:
(a) (0, 11)

The science club members are using transformations on coordinate grids to track the movement of constellations in the sky. Choose the left side of the constellation depicted by the line passing through (1,7) and (2.5,1), and find the linear functions that correspond to the series of motions of the side given below.
The linear function passing through points (1,7) and (2.5, 1) is given by:
y = -4x + 11.
What is a linear function?A linear function, in slope-intercept format, is modeled according to the rule presented below:
y = mx + b
In which the coefficients are described as follows:
The coefficient m is the slope of the function, representing the rate of change of the function.The coefficient b is the y-intercept of the function, representing the value of y when the function crosses the y-axis(x = 0).For this problem, the two points that form the function are given as follows:
(1,7) and (2.5, 1).
The slope is given by change in y divided by change in x, hence it is given by:
m = (1 - 7)/(2.5 - 1) = -4.
Then:
y = -4x + b.
When x = 1, y = 7, hence we can find the intercept b of the function as follows:
7 = -4(1) + b
b = 7 + 4
b = 11.
Hence the equation is:
y = -4x + 11.

A factor may be defined as a number of another number which when divided by the other number leaves no remainder or it completely divides the other number. For example, 2 is a factor of 4 as when 4 is divided by 2 the remainder is zero. Now, we are given in the question that we need to factor -6 out of 18z - 15. In order to do that we divide and multiply -6 from the given expression. This can be represented as

What is a scatterplot?
A scatterplot (also known as a scatter plot, scatter graph, scatter chart, scattergram, or scatter diagram) is a form of plot or mathematical diagram that uses Cartesian coordinates to represent values for a collection of data for generally two variables. One more variable can be presented if the points are coded (color/shape/size). The data is represented as a collection of dots, with the value of one variable defining the horizontal axis and the value of the other variable determining the vertical axis. A scatterplot can be used when one continuous variable is within the experimenter's control and the other is reliant on it, or when both continuous variables are independent.

Answer:
y = - 2x + 12
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
