Step-by-step explanation:
3x4=12
5x6=30
12/30
simplified would be 12/30 divided by 2/2
the answer is 6/15
Answer:
3x4=12 and 5x6=30
Step-by-step explanation:
This is because 5x5x5x5x5x5 6 times equal 30 and 3x3x3x3 4 times equals 12. Thank u for your time.

The number of shoes a cobbler (shoemaker) can make varies directly with the amount of time the cobbler spends making the shoes.
If the cobbler can make 3 pairs of shoes in two hours, how would you write this equation?
Group of answer choices
y=3x
y=4x
y=2x
y=1. 5x
The pairs of shoes increases as the time the cobbler works increases
The equation of the pairs of shoes is y = kx
How to determine the equation?The variation is a direct variation.
So, we have:
y = kx
Where:
y represents the number of shoesx represents the time in hoursk represents the proportionality constantThe cobbler can make 3 pairs of shoes in two hours,
So, we have:
k = 3/2
k = 1.5
Substitute k = 1.5 in y = kx
y = 1.5x
Hence, the equation of the scenario is y = kx

A golf ball is hit so that it travels a horizontal distance of 400 feet and reaches a
maximum height of 190 feet.
Determine a quadratic equation that models the path of the golf ball, assuming it starts at the origin.
Considering the vertex, the quadratic equation that models the path of the golf ball is given by:
y = -0.0011875(x - 400)² + 190
What is the equation of a parabola given it’s vertex?The equation of a quadratic function, of vertex (h,k), is given by:
y = a(x - h)² + k
In which a is the leading coefficient.
In this problem, the vertex is at the maximum height of the parabola, given by (400, 190), hence h = 400, k = 190, and:
y = a(x - 400)² + 190
It starts at the origin, that is, when x = 0, y = 0, hence:
0 = 400²a + 190
a = -190/400²
a = -0.0011875.
Hence, the equation is:
y = -0.0011875(x - 400)² + 190

Write the equation of the graph.
y−3=12(x+1)

What is the equation below in slope-intercept form?
15x−3y=−12
y = -4x + 8
y = -15x -12
x = 3y - 12
x - y = 6
Answer:
1. Given the slope is 2, the equation now looks like y = 2x +b Given P (−1,4) we can solve for the b variable by substituting the x and y cordinates. 4 = 2 ⋅ (− 1) + b 4 = − 2 + b b = 6 Therefore the equation that has the slope of 2 and passes through the point (− 1,4) is y = 2x + 9 so it is d
2. i you can do that.
3. The equation for the slope of a line and the points also called point slope form of equation of a straight line is given by: y − y1 = m (x − x1) Whereas the slope-intercept form the equation of the line is given by: y = mx + b. Where b is the y-intercept.
4.In the formula,y = the y-coordinate of any point on the line,m = slope,x = the x-coordinate of any point on the line,and b = ...
Plug the slope and y-intercept into the formula. Remember,the slope is equal to the rise over the run.

Which ordered pair is a solution to the system of linear equations? 2x 3y= 6 –3x 5y = 10 (0,2) (2,0) (3,2) (2,3)
An equation is formed of two equal expressions. The ordered pair which is the solution of the system of linear equations is (0,2).
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
The solution of the equation can be done in the following manner.
2x+3y=6
3x+5y=10
Let's take the first equation and find write it in terms of y. therefore, the first equation can be written as,
[tex]2x+3y=6\\\\2x=6-3y\\\\x = \dfrac{6-3y}{2}[/tex]
Now, substitute the value of x in the second equation,
[tex]3x+5y=10\\\\3(\dfrac{6-3y}{2})+5y=10\\\\18-9y +10y = 20\\\\-9y+10y=20-18\\\\y=2[/tex]
Thus, the value of y is 2. substituting the value of y in the first equation to get the value of x.
[tex]2x+3y=6\\\\2x+3(2)=6\\\\2x=6-6\\\\x=0[/tex]
Hence, the ordered pair which is the solution of the system of linear equations is (0,2).

The numbers given below that fall within the mean absolute deviation of the data are: C. 12,990, D. 12,705, E. 12720.
What is the Mean Absolute Deviation?The mean absolute deviation is simply the average of the distance of each of the data points there are in a data distribution.
The difference of each data point from the mean is most likely within the same range with the mean absolute vallue.
If we subtract 12,990, 12,705, and 12720 from the mean of the data, 12,367, we would get a figure close to the mean absolute deviation, 350.

Linda rented 8 movies and 4 video games for a total of $37. The next month she rented 3 movies and 2 video games for a total of $17. Find the rental cost for each movie and each video game.
Answer:
Let x = the price of movies and let y = the price of video games
8x + 3y = 43
2x + 5y = 32
Use the Elimination Method by multiplying both sides of the second equation by 4
8x + 3y = 43
-(8x + 20y = 128)
-17y = -85
y = 5
2x + 5(5) = 32
2x + 25 = 32
2x = 7
x = 7/2 = 3.5

Complete the table of successive approximation to find the x-value of the solution of f(x)=g(x) to the nearest hundredth f(x)= x^2-2 g(x) = x-1
The solution of f(x)=g(x) to the nearest hundredth if f(x)= x^2-2 g(x) = x-1 is 1.62 or -0.62
How to find the solution to a given set of function?Given the following function below:
f(x) = x^2 - 2
g(x) = x - 1
Since f(x) = g(x), hence;
x^2 - 2 = x - 1
x^2 - x - 1 = 0
Factorize to have:
x = 1/2 +√5/2 or x= 1/2 - √5/2
x = 1.62 or -0.62
Hence the solution of f(x)=g(x) to the nearest hundredth if f(x)= x^2-2 g(x) = x-1 is 1.62 or -0.62
