The expression in the mathematical form will be 17 / 3.

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

PEMDAS rule means for the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.

Translate the phrase into an algebraic expression: k dollars per 28 bottles.

Then the division of the numbers k and 28 will be given by putting a division sign between them. Then we have

⇒ k ÷ 28

⇒ k / 28

Step-by-step explanation:

→Find a common factor of 5 and 25

5

→ Now factorise

5a ( x + 5y )

The value of the equation is A = 5a ( x + 5y )

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 ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

A = 5ax + 25ay   be equation (1)

On simplifying the equation , we get

On factorizing the equation by taking the common factor as 5a , we get

A = 5a ( x + 5y )

Therefore , the value of A is 5a ( x + 5y )

Hence , the equation is A = 5a ( x + 5y )

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

In the Cartesian coordinate system, a line perpendicular to the line that's across the Y axis is a row across the X axis. You see Y=1 is the line across Y axis, so we need a row that's across the X axis. So C. X=4 is the ideal choice.

If a line is drawn on a coordinate grid by the equation y = 1 then x=4 would represent a row perpendicular to it.

A coordinate geometry is a branch of geometry where the position of the points on the plane is defined with the help of an ordered pair of numbers also known as coordinates.

A line is drawn on a coordinate grid by the equation y = 1.

The equation y = 1 represents a horizontal line on the coordinate grid, passing through all the points where y-coordinate is 1.

A line that is perpendicular to a horizontal line is a vertical line.

The vertical line x = 4 passes through all the points where x-coordinate is 4, and is perpendicular to the horizontal line y = 1.

Hence, if a line is drawn on a coordinate grid by the equation y = 1 then x=4 would represent a row perpendicular to it.

Two or more expressions with an Equal sign is called as Equation.

Given that Members of a lacrosse team raised $1670.50 to go to a tournament.

The rent of the bus is $1013.50.

Now we need to find the left out fund after removing the rent of bus.

so one thousand six hundred and seventy point five minus one thousand and thirteen point five equal to six hundred and fifty seven.

1670.5-1013.5 = $657

The budget for each meal of player is $54.75.

Divide $657 by $54.75. to get the number of players.

  c.  $76.17 billion

Step-by-step explanation:

The relations between imports, exports, and tariffs can be described by ...

  0.06E +0.21I = $18.9603 . . . . . . total tariff revenue

  I -E = 26.76 . . . . . . . . . . . . . . . . trade deficit

Solving the second equation for E gives ...

  E = I -26.76

Substituting into the first equation yields ...

  0.06(I -26.76) +0.21I = 18.9603

  0.27I = 18.9603 +1.6056 = 20.5659 . . . . add 1.6056 to both sides

  I = 10.5659/0.27 = 76.17

Romania's imports are worth about $76.17 billion.

a. The number of rolls of wrapping paper it will take to cover the new box is 2¹/₄ rolls

b. The volume of the new rectangular box is 270 in³

Since the small box is a rectangular prism, its surface area, A = 2(lb + lh + bh) where

Now, when the dimensions are tripled, its new area is A' = 2(LB + LH + BH) where

So, A' = 2(LB + LH + BH)

= 2((3l)(3b) + (3l)(3h) + (3b)(3h))

= 2(3)(3)(lb + lh + bh)

= 18A

The number of rolls of wrapping paper it will take to cover the new box is 2¹/₄ rolls

Now, since we require 1/8 of a roll of wrapping paper to initially cover all 6 sides of the small box with dimensions, l,b and h. Then the number of rolls we require to cover the box when its dimensions are tripled are (since the area is proportional to the number of rolls)

N = 18 × 1/8

= 18/8

= 9/4

= 2¹/₄ rolls

The number of rolls of wrapping paper it will take to cover the new box is 2¹/₄ rolls

The volume of the new rectangular box is 270 in³

The volume of the rectangular box V = lbh where

When the dimensions are tripled, V' = LBH where

So, V' = LBH

= (3l)(3b)(3h)

= 27lbh

= 27V

Now since the initial volume of the rectangular box, V = 10 in³

V' = 27V

V' = 27 × 10 in³

V' = 270 in³

So, the volume of the new rectangular box is 270 in³

Answer:

30.4/15 = 2 2/75

Step-by-step explanation:

Step 1 - Find Whole Number

Calculate out how many times the denominator goes into the numerator. To do that, divide 30.4 by 15 and keep only what is to the left of the decimal point:

30.4 / 15 = 2.026666667 = 2

Step 2 - Find New Numerator

Multiply the answer from Step 1 by the denominator and deduct that from the original numerator.

30.4- (15 x 2) = 0.4

Step 3 - Get Solution

Keep the original denominator and use the answers from Step 1 and Step 2 to get the answer. 30.4/15 as a mixed number is:

2 0.4/15 = 2 2/75

Answer:

x= 0, y= -15

Step-by-step explanation:

Start by labelling the 2 given equations.

y= -2x -15 -----(1)

y= -15 +3x

y= 3x -15 -----(2)

Substitute (1) into (2):

-2x -15= 3x -15

3x +2x= -15 +15

5x= 0

Divide both sides by 5;

x= 0

Substitute x= 0 into (2):

y= 3(0) -15

y= -15

Answer:

Let eqn 1 be y = -2x -15

and Eqn2 be y-3x =-15

Substitute Eqn 1 into Eqn 2

where -2x-15-3x = -15

-5x = 0

X is 0

from Eqn1 the value of y Will be

-2(0) - 15

Value of y is -15

Therefore (X,y) = (0, -15)
