Dylan has a total of 25 marbles. He gives ! marbles to his sister, Jane. What fraction
of marbles did Jane receive?
Answers
The Dylan sister Jane received 1/5 marbles, which is a part of 25 if the Dylan has a total of 25 marbles.
What is a fraction?Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.
The total number of marbles Dylan has = 25
The total number of marbles Dylan gave to his sister = 5
If we choose one marble out of 25 = 1/25
If we choose 5 marbles = 5(1/25) = 1/5
Thus, the Dylan sister Jane received 1/5 marbles, which is a part of 25 if the Dylan has a total of 25 marbles.

It mentions that they add up to 15.
Then the possible numbers are :
69 (6 + 9 = 15)78 (7 + 8 = 15)=============================================================
Let's reverse the numbers :
69
69 ⇔ 9696 - 69 = 27Not the right number ×78
78 ⇔ 8787 - 78 = 9This is correct √=============================================================
Solution :
Hence, the number needed is 78
Step-by-step explanation:
no. 10y+x
no. formed by reversing the digits = 10x+ y
ATQ
EQ(1)= x+y=15
EQ (2)=10x+y+9=10y +x ( Digits are reversed)
9x-9y=-9
x-y=-1
x+y=15 ( given)
2x=14,x=7
and y=15–7=8
thus the number=78

Answers
Based on the calculations, the function which best models the data in the graph is y = 10.1x + 101.
How to determine the function?Mathematically, the equation of a line in standard form is given by this formula:
y - y₁ = m(x - x₁)
Where:
m is the slope.y is the point on the horizontal axis.x is the point on the vertical axis.In order to determine the function which best models the data in the graph shown in the image attached below, we would calculate the slope of the data by using this formula:
[tex]Slope = \frac{Change\;in\;y\;axis}{Change\;in\;x\;axis}\\\\Slope = \frac{y_2\;-\;y_1}{x_2\;-\;x_1}\\\\Slope = \frac{202\;-\;101}{10\;-\;0}\\\\Slope = \frac{101}{10}[/tex]
Slope = 10.1.

billy has 2.4m of ribbon for crafts. he wants to share it evenly with 12 friends. how many centimeters of ribbon would 7 friends get
Answers
You would have to do 2.4 divided by 12 to get 0.2. Then multiply 0.2 by 7 to get 1.4.
Answer:
140cm
Step-by-step explanation:
We first have to change 2.4 meters into centimeters. And the formula for that is (x)m = (x)cm x 100.
So 2.4 x 100 = (x)m. We can solve this by moving the "." two times to the right and we will get 2.4m = 240cm.
The next step is to divide it by twelve because Billy wants to share it with 12 friends. 240cm/12 = 20cm per person.
Then we have to multiply 20 with 7 to see how many centimeters 7 friends would get.
20*7 = 140. So the answer is 140cm.

4.1 When a fraction equals zero ...
Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.
Now, to get rid of the denominator, I multiply both sides of the equation by the denominator.
Here's how:
5y-4x-47
———————— • 5 = 0 • 5

Now, on the left hand side, the 5 cancels out the denominator, while, on the right hand side, zero times anything is still zero.
The equation now takes the shape :
5y-4x-47 = 0
Equation of a Straight Line
4.2 Solve 5y-4x-47 = 0
CalderonJ recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).
"y=mx + b" is the formula of a straight line drawn on a Cartesian coordinate system in which "y" is the vertical axis and "x" is the horizontal axis.
In this formula :
y tells us how far up the line goes
x tells us how far along
m is the Slope or Gradient i.e. how steep the line is
b is the Y-intercept i.e. where the line crosses the Y axis
The X and Y intercepts and the Slope are called the line properties. We shall now graph the line 5y-4x-47 = 0 and calculate its properties
Notice that when x = 0 the value of y is 47/5 so this line "cuts" the y axis at y= 9.40000
y-intercept = 47/5 = 9.40000
Calculate the X-Intercept :
When y = 0 the value of x is 47/-4 Our line therefore "cuts" the x axis at x=-11.75000
x-intercept = 47/-4 = -11.75000
Calculate the Slope :
The slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is 9.400 and for x=2.000, the value of y is 11.000. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of 11.000 - 9.400 = 1.600 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)
Slope = 1.600/2.000 = 0.800
