help solve this equation
Answer:
If you're supposed to use elimination to find (x, y) the answer is (6, 1)
Step-by-step explanation:
Add:
2x+3y=15
x-3y= 3
y cancels out and left with...
2x=15
x=3
that becomes
3x=18
find x
18/3= 6
x=6
Then plug in x (which is 6) to one of the equations to solve for y
6- 3y= 3
-3y= 3-6
-3y= -3
y= 1
(x, y) equals (6, 1)
A ribbon is 5 2 5 yards long. Mae needs to cut the ribbon into pieces that are 2 5 of a yard long. How many pieces of ribbon can she cut?
Answer: The number of pieces of the ribbon she can cut = [tex]13\frac12[/tex] yards
Step-by-step explanation:
Given: The length of the ribbon = [tex]5\dfrac25[/tex] yards
[tex]= \dfrac{5\times5+2}{5} =\dfrac{27}{5}[/tex] yards
Length of each piece = [tex]\dfrac25[/tex] yards
The number of identical pieces can be cut from the entire ribbon = (Length of the ribbon ) ÷ (Length of each piece )
[tex]=\dfrac{27}{5}\div\dfrac{2}{5}\\\\=\dfrac{27}{5}\times\dfrac{5}{2}\\\\=\dfrac{27}{2}\\\\=13\dfrac12[/tex]
Hence, the number of pieces of the ribbon she can cut = [tex]13\frac12[/tex] yards
solve for x
350 = 25(x+4)
Answer:
Step-by-step explanation:
I'm just going to reverse the equation because I'm more comfortable with the x being on the left side:
25(x+4) = 350
Do distributive property (I'll explain down below if you don't know what that is):
25x+100=350
Same to both sides
25x = 250
Divide 25 on both sides
x = 10
Distributive property is when there are multiple terms inside the parenthesis and 1 or more term outside of it
To show this works, lets do 6(5+1)
We can either do 6*6 or we can do 30+6 and we get the same answer

There are 4 female and 4 male kittens are sleeping together in a row. Assuming that the arrangement is a random arrangement, what is the probability that all the female kittens are together, and all the male kittens are together?
Answer:
I beleive the answer is 8
Step-by-step explanation:
4+4=8
The probability that the female kittens are together, and all the male kittens are together is 1/35.
What is Permutation?Permutation is defined as the calculation of a set such that it defines the number of ways that something can be arranged.
Let A represents the arrangements of 8 kittens which includes 4 male and 4 female.
N(A) = 8P₈ / (4! × 4!) = 8! / (4! × 4!) = 70
Let B represents the arrangement of kittens such that 4 males are together and 4 females are together.
N(B) = 2
Probability of arranging kittens in such a way that all the female kittens are together, and all the male kittens are together = 2/70 = 1/35
Hence the required probability is 1/35.

The table below summarises the number of books in some students' schoolbags.
Number of books Frequency
1 3
2 5
3 12
4 25
5 4
6 1
How many students are included in this data set?
Answer:
Total number of students = 50 students.
Step-by-step explanation:
Total number of books = number of books * frequency
1 * 3 = 3
2 * 5 = 10
3 * 12 = 36
4 * 25 = 100
5 * 4 = 20
6 * 1 = 6
Total number of books = 3 + 10 + 36 + 100 + 20 + 6
Total number of books = 175 books.
Now, to find the total number of students;
Total number of students = summation of frequency
Total number of students = 3 + 5 + 12 + 25 + 4 + 1
Total number of students = 50 students.

Answer:
The possible range of the length of side LM is 8 < x < 26 ⇒ A
Step-by-step explanation:
In any triangle:
The sum of the lengths of any two sides must be greater than the length of the 3rd sideThe length of any side must greater than the difference of the lengths of the other two sidesThe difference of the other sides < The side < The sum of the other sidesIn the given figure
∵ LMN is a triangle
∵ LM = x, MN = 9, NL = 17
→ Find the sum of the lengths of MN and NL
∴ The sum of the lengths of MN and NL = 9 + 17 = 26
→ Find the difference between the lengths of MN and NL
∴ The difference between the lengths of MN and NL = 17 - 9 = 8
→ By using the rules above, x should be between 8 and 26
∴ 8 < x < 26
∴ The possible range of the length of side LM is 8 < x < 26

xyz angle=23.6°The volume of a rectangular prism is given by the product of its length, and height. Samantha has a rectangular prism that has a length of b squared units, a width of a units, and a height and ab+c units.
Answer:
V = a²b³ + acb² units³
Step-by-step explanation:
The volume of a rectangular prism is given by :
V = l×b×h
Here, l = b² units
b = aunits
h = ab+c units
So, the volume of the prism is given by :
V = b² × a × (ab+c)
= ab²(ab+c)
= a²b³ + acb²
Hence, the required volume is a²b³ + acb² units³.

The vertex of the graph of f(x) = |x - 3| +6 is located at
Done
Intro
Answer:
The vertex of the graph is located at the point (3,6)
Step-by-step explanation:
Here, we want to know where the vertex of the equation if plotted will be
To get this, what we have to do is to equate the expression that we have in the absolute value to zero
After this, we then proceed to solve for the value of x
We have this as;
x -3 = 0
hence;
x = 0 + 3
x = 3
to get the y-value of the vertex, we look at the value at the side of the absolute value
This value is 6 and thus, the y-value of the vertex point is 6
So the coordinates of the vertex is (3,6)
