Answer: Subtract 3 from each side

Step-by-step explanation:

The goal of the problem is to isolate 3 on one side by itself. The only thing standing in our way is that pesky three. In order to get rid of it, and make y have the whole left side to themselves, we have to see what is three doing in the equation. Well, it is a positive three and it is being added to y. So, we want to do the opposite of what it is. Since it is a positive three, we are going to subtract three on both sides. It will zero itself out on the left side and move on over to the right side, giving y the entire left side of the equation.

The tree A is 3t taller than tree B.

Equation to represent tree A = 16 + 6t

Equation to represent Tree B= 37+ 7t

A linear equation is an algebraic equation of the form y=mx+b. involving only a constant and a first-order (linear) term, where m is the slope and b is the y-intercept.

Given that : Tree A was 16 inches tall and Tree B was 37 inches tall.

Tree after 't' year

A= 16 + 6t

B = 37 + 7t

so,

A-B= 16 + 6t -(37+3t)

    = 16 + 6t - 37 -3t

    = 3t- 21

As tree A grew 2 times the tree B

then t'= 2t

A'- B'= 3t' -21

        = 3(2t)-21

        =6t -21

Thus, (A'- B')(A-B) = 6t-21- (3t-21)

                   = 6t-3t

                   = 3t

Hence the tree A is 3t taller than tree B

Equation to represent Tree A = 16 + 6t

                                     Tree B= 37+ 7t

Answer:

The sample mean (x⁻ ) is the point of estimate of the Population mean

x⁻ = 7.7

The sample standard deviation   (S)  is the point of estimate of the Population standard deviation

 S = 3.65

Step-by-step explanation:

Step(i):-

Given data    12  7  6  3   5   12   9   10  11  2

Mean of the data

          [tex]x^{-} = \frac{12+7+6+3+5+12+9+10+11+2}{10} = 7.7[/tex]

x          :     12      7       6       3        5         12      9       10           11        2

x-x⁻      :   4.3     -0.7    -1.7   -4.7    -2.7     4.3    1.3      2.3         3.3     -5.7

(x-x⁻  )² :  18.49  0.49   2.89  22.09 7.29  18.49 1.69    5.29  10.89   32.49

Step(ii):-

Standard deviation of the sample

[tex]S^{2} = \frac{sum (x-x^{-})^{2} }{n-1} = \frac{120.1}{10-1} = 13.344[/tex]

Standard deviation of the sample

 S = √13.344 =3.65

Final answer:-

The sample mean (x⁻ ) is the point of estimate of the Population mean

x⁻ = 7.7

The sample standard deviation   (S)  is the point of estimate of the Population standard deviation

 S = 3.65

Answer:

12 = 4

Step-by-step explanation:

Answer:

c ⋅ 4 = 12

Step-by-step explanation:

We know that on the right side of the hanger, it holds one square, and that square has a value of 12 units.

And on the left side, the hanger holds four pentagons, and each pentagon has a value of c.

So, we know that 4 pentagons equal one square, or 4c = 12.

So how can we make that into an equation?

To get 4c, we multiply c four times. It should look like this:

c ⋅ 4 = 4c

And, we know that 4c equals 12, so all we have to do is make an equation showing that. You should get:

c ⋅ 4 = 12

 *If you are looking for the value of c, you should get 3 because 3 ⋅ 4 = 12, proving c = 3

Answer:

-2.8 x 10^5 or -280,000

Step-by-step explanation:

We first have to look at:

P : Parenthesis

E : Exponents

M : Multiply

D : Divide

A : Add

S : Subtract

We have to solve the question in that order:

The first thing we do is figure out the value of the exponents from left to right since there are exponents inside the parenthesis.

10^4 is just 10x10x10x10 = 10,000

10^5 same thing 10x10x10x10x10 = 100,000

Now that we know the value of the exponents we can solve the equations inside the parenthesis:

12 x 10,000 = 120,000

(120,000) - ( 4 x 100,000)

4 x 100,000 = 400,000

So the final expression is:

(120,000) - (400,000) = -280,000

Answer: 12(5x - y)

Step-by-step explanation:

60x - 12y can be factorized as 12(5x - y).

Factorization is the process of writing a number or expressions as a product of it's factors. In other words, it is the breaking down of a single number or expression into many using it's factors. When we multiply these factors altogether, we will get the original number.

Factorization can be done to numbers or expressions like polynomials and matrices as well.

We have two terms here, 60x and 12y.

Let us find the common factor of 60x and 12y.

12 is a common factor of both 60x and 12y.

60x = 12 × 5x and 12y = 12 × y

Taking 12 outside the bracket indicating as a common term,

60x - 12y = 12 (5x - y)

Hence, 60x - 12y is factorized as 12(5x - y).

Answer:

[tex]Length = 15cm[/tex]

Step-by-step explanation:

Given

The cross-section

[tex]Volume = 630cm^3[/tex]

Required

Calculate the length

We start by calculating the area of the trapezium cross-section.

[tex]Area = \frac{1}{2}(Sum\ of\ parallel\ sides) * Height[/tex]

[tex]Area = \frac{1}{2}(9cm + 5cm) * 6cm[/tex]

[tex]Area = \frac{1}{2}* 14cm* 6cm[/tex]

[tex]Area = 42cm^2[/tex]

The length is then calculated from volume as:

[tex]Volume = Area * Length[/tex]

Substitute values for Volume and Area

[tex]630cm^3 = 42cm^2 * Length[/tex]

Make Length the subject

[tex]Length = \frac{630cm^3}{42cm^2}[/tex]

[tex]Length = 15cm[/tex]
