what is 9/12 in simpleist form

Answer:

True.. :) Have a nice day.

Step-by-step explanation:

TRUE , the two system of equations are equivalent

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

We have two sets of equations

Let the first set of equation be A

Let the second set of equation be B

Equation set A :

6d + 4.5e = 16.5    be equation (1)

5d + 0.5e = 4   be equation (2)

Equation set B :

30d + 22.5e = 82.5   be equation (3)

5d + 0.5e = 4   be equation (4)

Now , we can see that Equation (3) is a multiple of Equation (1)

Multiply equation (1) by 5 , we get

5 ( 6d + 4.5e = 16.5 )

30d + 22.5e = 82.5   be equation (5)

Therefore , equation (5) = equation (3)

So , equation (1) = equation (3)

And , equation (2) = equation (4)

Therefore , Equation set A is equivalent to Equation set B

Hence , the two system of equations are equivalent

Answer:

width of given rectangle = 6 cm

length of given rectangle =  4 cm

Step-by-step explanation:

Let the breadth be x cm

given that

The length of a rectangle is eight centimeters less than twice its width

length of rectangle in terms of x =  2(breadth ) - 8 =  2x - 8

we know perimeter of rectangle is given = 2(l + b)

thus, perimeter of given rectangle is = 2 ( x +  2x - 8) = 6x - 16

also given perimeter of the rectangle is 20 centimeters

thus,

6x - 16 = 20

6x = 20 + 16 = 36

x = 36/6 = 6

Thus,

width of given rectangle = 6 cm

length of given rectangle = 2*6 - 8 = 4 cm

Answer:

Step-by-step explanation:

this is called a ratio and proportion or similar triangles

  21    =     35

x = 52.5 cm

Answer:

4

Step-by-step explanation:

I am not 100% sure but it should be 4

The input values that corresponds to f(x) = 4 are -1 and 8.

The correct answers are A and G.

A relation between a collection of inputs and outputs is known as a function. A function is a connection between inputs in which each input is connected to precisely one output. Each function has a range, co-domain, and domain.

Given function:

f(x) = 4

To find the input value of x;

Let the function,

y = f(x)

4 = f(x)

That means, y = 4.

From the attached graph;

We interpreted two values

x = -1 and 9 where  f(x) = 4

Therefore, -1 and 9 are the values.

Answer:

$0.68 per pound

Step-by-step explanation:

The price of sugar is $0.68 per pound.

A ratio indicates the number of times one number contains another.

Given that, the person paid $8.16 for 12 pounds of sugar.

Therefore, mathematically it can be written as:

12 pounds of sugar = $8.16

1 pound of sugar = $(8.16/12)

1 pound of sugar = $0.68

Hence, the price of sugar is $0.68 per pound.

Answer:

Below.

Step-by-step explanation:

The total number of marbles is 12.

Part A.

Prob(Red marble) = 5/12.

Part B.

Prob(pick 3 red marbles without replacement) = 5/12 * 4/11 * 3/10 = 1/22.

Part C.

The probability of the first being red is 5/12 because there are 5 red out of a total of 12 marbles. After that there are only 4 marbles and the total is 11 ( 1 marble less). Finally on the 3rd pick there are 3 red and a total of 10. WE then multiply these 3 probabilities.

The solution is: in the expression (5w+3) the value of w is: w = -3/5.

Here, we have,

given that,

the expression is: (5w+3)

now, we have to find the value of w

so, we get,

we can find the value of w by making it equal to 0:

5w+3 = 0

<- subtract 3 from both sides

5w = -3  

<- divide 5 from both sides

5w/5 = -3/5

so, we have,

w = -3/5 is the final answer.

Hence, The solution is: in the expression (5w+3) the value of w is: w = -3/5.
