Answer:
The number '1' is called the 'multiplicative identity' of a number '-12/13' because it does not change the number '-12/13' after getting multiplied by it.
Therefore, option (B) is true.
Step-by-step explanation:
We know that when a number let say 'n' get multiplied by '1', it remains unchanged.
i.e.
n × 1 = n1 × n = nThe number '1' is called the 'multiplicative identity' of a number 'n' because it does not change the number 'n' after getting multiplied by it.
Given the number
-12/13
Multiply the number '-12/13' by '1'.
i.e.
-12/13 × 1 = -12/13
1 × -12/13 = -12/13
Thus, the number '1' is called the 'multiplicative identity' of a number '-12/13' because it does not change the number '-12/13' after getting multiplied by it.
Therefore, option (B) is true.

First, divide 108 by 12.
The result is 9.
Now square root 9.
The result is 3.
Now, multiply 12 by 3.
The result is 36.
To check that this is the pattern, we multiply 36 by 3, and we indeed see that 3 times 36 is equal to 108.

Leila bought 3 bananas, which weighed a total of Three-fourths of a pound. If each banana weighed the same amount, what is the weight of each banana? StartFraction 1 Over 12 EndFraction of a pound StartFraction 1 Over 9 EndFraction of a pound One-fourth of a pound One-third of a pound
Answer:
[tex]Each\ Weight = \frac{1}{4}[/tex]lb
Step-by-step explanation:
Given
[tex]Weights = \frac{3}{4}lb[/tex]
[tex]Bananas = 3[/tex]
Required
Determine the weight of each
To do this, we simply divide the total weight by the number of bananas.
[tex]Each\ Weight = \frac{3}{4}/3[/tex]
Convert to multiplication
[tex]Each\ Weight = \frac{3}{4} * \frac{1}{3}[/tex]
[tex]Each\ Weight = \frac{1}{4}[/tex]
Hence, each banana weighs 1/4 of a pound

What is the independent variable (x) for this situation?
number of cases of paper
not enough information to determine independent quantity
cases of paper per tree
number of trees used
trees used per case of paper
Answer:
The independent variable would be
trees used per case of paper
Step-by-step explanation:
Answer:
Number of trees used
Step-by-step explanation:
The number of trees used is the independent variable because it doesn't depend on anything, meaning it isn't changed by other variables. The number of cases of paper would be the dependent variable because it depends on the number of trees used.

10/3 = x divided by -5/2
x =?
Answer:
-0.3x
Step-by-step explanation:
if you divide all of the number up you will get -0.3x
Answer:
Not possible
Step-by-step explanation:
The reason why its not possible is because to figure out a x type of problem, there needs to be a answer to it.
Lets try it solve it to make better sense.
10/3 = 3.33333333333
-5/2 = -2.5.
Divide.
= -1.33333333333.
If this is possible, the answer is -1.33333333333.

O f(x) =3x + 10
O fx) = 2x + 3
O fx)= 4x +5
O fx) =3x-10
The function with the domain is given by f ( x ) = 2x + 3
What is a function rule?The function rule is the relationship between the input or domain and the output or range. A relation is a function if and only if there exists one value in the range for every domain value.
A function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.
Given data ,
Let the function be represented as A
Now , the value of A is
Let the x values be x = { -7 , -1 , 3 , 4 , 7 )
Let the y values be y = { -11, 1 , 9 , 11 , 17 }
Now , the function is given as
f ( x ) = 2x + 3 be equation (1)
when x = -7
y = 2 ( -7 ) + 3
y = -11
when x = 7
y = 2 ( 7 ) + 3
y = 17
Hence , the function is f ( x ) = 2x + 3

Answer:
x=-1
Step-by-step explanation:
Step 1: Subtract x from both sides.
−x+4−x=x+6−x
−2x+4=6
Step 2: Subtract 4 from both sides.
−2x+4−4=6−4
−2x=2

Zoey made 6 1/2 cups of trail mix for a camping trip. She wants to divide the trail mix into 3/4 cup of servings. Twelve people are going on the camping trip. Can zoey make enough 3/4 cup servings so that each person on the trip has on serving?
Answer:
No
Step-by-step explanation:
Given that:
Total number of cups of trail mix available for camping trip = [tex]6\frac{1}{2}[/tex]
Amount of one serving contains = [tex]\frac{3}{4}[/tex] cups
Number of people at the trip = 12
To find:
Whether each person will be able to get the servings?
Solution:
Here, we can find the total number of servings by dividing the total number of cups of trail mix with the amount of one serving.
First of all, let us convert the mixed fraction into fractional number.
[tex]6\dfrac{1}{2} = \dfrac{6\times 2+1}{2} = \dfrac{13}{2}[/tex]
Therefore, total number of servings available as per the given quantities:
[tex]\dfrac{\frac{13}2}{\frac{3}4}\\\Rightarrow \dfrac{13\times 4}{2\times 3} \\\Rightarrow \dfrac{26}{3}\\\Rightarrow \approx 8[/tex]
So, With this type of servings Zoey will be able to serve only 8 people.
Therefore, there is not enough servings.

Answer:
x=7
y=14
Step-by-step explanation:
this is a special 30-60-90 right triangle bc there is a right angle marker and a 60 degree and 30 degree angle
in 30-60-90 right triangles the short leg is x, the long leg is x√3, and the hypotenuse is 2x
it is given that the long leg is 7√3, and since the long leg equals x√3, then x equals 7
so the short leg, x, is 7 and since the hypotenuse is 2x, 2(7) =14

Which of the followin statements are true about the equation 10x + 45x - 13 = 11(5x + 6) *
Step-by-step explanation:
The given expression is :
10x + 45x - 13 = 11(5x + 6)
We can simplify it as follows :
Opening parenthesis on RHS
10x + 45x - 13 = 55x + 66
Taking like terms together,
55x-55x = 13+66
0 = 13+66
The given expression has no solution, as the variable cancels out woh each other. It is a meaningless expression.
