Transitive property of equality

Step-by-step explanation:

Answer:

You can represent "the opposite of Shana's temperature is equal to Pearl's" as follows:

(-20 C) + (-x) = x

Where x represents Pearl's temperature.

Alternatively, you can also write it as:

20 C - x = x

Both of these equations are equivalent and mean the same thing: the opposite of Shana's temperature is equal to Pearl's temperature.

Step-by-step explanation:

20 degrees Celsius

The temperature in Pennsylvania is the opposite of the temperature in Canada, therefore -20⁰ Celsius in Canada would then be 20⁰ Celsius in Pennsylvania.

$1052 is the total saving og Ms. Davis after 30 weeks from the given point .

Given that:

Inital saving of Ms. Davis = $54.50

Ms. Davis has already saved $54.50 and plans to save an additional $33.25 each week for the next 30 weeks. This means that she will be adding a total of $33.25 x 30 = $997.50 to her savings over the next 30 weeks.

If she does not spend any of the money she has saved, her total savings will be :

sum of Initial saving and saving after 30 weeks

$54.50 + $997.50 = $1,052.00.

so the total saving is $1052.

Answer:

m/_A= 84

Step-by-step explanation:

Answer:

y=x+1

Step-by-step explanation:

first find the slope using the two coordinates:

use the slope formula- m=y^2-y^1/x^2-x^1

6-2/5-1

=4/4

=1

y=mx+b

now plug in one of the coordinates, and the slope we just found into the slope intercept formula

2=1(1)+b

2=1+b

subtract 1 from both sides

1=b

1=b; m=1,

y=x+1

Answer:

x = -2

y = -8

Step-by-step explanation:

y = 3x – 2

y = 4x

Substituting the second equation for y into the first

4x = 3x - 2

Subtract 3x from both sides

x = -2

plug in x = -2 into the second equation

y = 4(-2)

y = -8

Taking into account the definition of a system of linear equations, the length and width of the rectangle is 22.5 cm and 19.5 cm respectively.

Systems of linear equations are groupings of first degree equations with the same unknowns, of which a common solution must be found.

In the systems of equations, the values of the unknowns must be found, with which, when replaced, they must give the solution proposed in both equations.

In this case, a system of linear equations must be proposed taking into account that:

You know:

The system of equations to be solved is

2x + 2y= 84

x= y + 3

The substitution method is a way to solve systems of equations. To use the substitution method, you choose an equation and find an expression for one of the variables in terms of the other variable. Then substitute that expression for the variable in the other equation.

In this case, substituting the second equation in the first one you get:

2×(y+3) + 2y= 84

Solving:

2y+ 2×3 + 2y= 84

2y+ 6 + 2y= 84

2y + 2y= 84 - 6

4y= 78

y= 78÷4

y= 19.5

Replacing this value in the second equation, you get:

x= 19.5 + 3

x= 22.5

Finally, the length of the rectangle is 22.5 cm and the width of the rectangle is 19.5 cm.

Answer: $1.05

Step-by-step explanation:

The profit made will be calculated as the difference between the selling price and the cos price. This will be:

= Selling price - Cost price

= $6.30 - $5.25

= $1.05

Therefore, Jerry will make $1.05 profit on each baseball card that's sold.

There will be a total of 430 pages in the book or the length of the book in pages = 430.

Adrianne reads 275 pages

She is left with 155 pages.

So, for converting the above in form of an equation,

Let us assume that the total pages in the book be x

Let us assume that the total number of pages she read = a

Assuming that the total remaining pages that she does not read = b

So, the total number of pages will be = total pages which she read + total remaining pages.

=> x = a+b

Now, solving the values given in the questions,

The value of a = 275 and the value of b = 155

So, the total number of pages in the book = 275+155 = 430

Which statement.........

Answer: 4/5 minus 5/10 can be simplified as:

(4/5) - (5/10)

It can also be re-written as

(4/5) - (1/2)

To subtract these fractions, we need a common denominator, which is 10 in this case.

So it becomes

(4/5)(2/2) - (1/2)(5/5) = 8/10 - 5/10 = 3/10

So the result of 4/5 minus 5/10 is 3/10 on a number line.

Answer:

A square of side length 40 m will give the maximum area of the play area

Step-by-step explanation:

Mathematically, it has been established that a square gives the maximum area of a quadrilateral

Hence, for us to have a maximum area of the given perimeter, we have to divide the perimeter by 4 to get the side length of the square

From what we have, we know that the perimeter of the fencing is 160 m

To get the side length, we divide the perimeter by 4

Side length of the shape would be 160/4 = 40 m

A is the variable and X is the coefficient term in the supplied  X2 expression. An algebraic expression is used to solve a particular mathematical problem .

In mathematics, a variable is an alphabet or phrase that denotes an unknowable quantity, unknowable value, or unknowable number. In the case of algebraic expressions or algebra, the variables are employed specifically. The two primary categories of variables are categorical and numeric. Then, for categorical and numerical variables, respectively, nominal or ordinal and discrete or continuous subcategories are created for each category. This section provides a quick overview of these types.

given

The coefficient term is denoted as X2, and the variable is A.

An algebraic expression is used to solve a particular mathematical problem by combining words and numbers.

For instance, the numerical coefficient in the equation 5x is 5, meaning that the variable x has been multiplied by 5 times.

Answer:

PF = 9

Step-by-step explanation:

the incentre of a triangle is equally distant from the triangle's 3 sides, that is

PD = PE = PF

using PD = PE to solve for x

5x - 6 = 3x ( subtract 3x from both sides )

2x - 6 = 0 ( add 6 to both sides )

2x = 6 ( divide both sides by 2 )

x = 3

then

PE = 3x = 3 × 3 = 9

PF = PE = 9

Answer:

Step-by-step explanation:

This is a binomial probability question.  "Makes" is what some writers call a "success."  In the binomial probability distribution, the probability of  r  successes in  n  trials is

[tex]\binom{n}{r}p^r(1-p)^{n-r}[/tex]

p is the probability of "success."  [tex]\binom{n}{r}=\frac{n!}{r!(n-r)!}[/tex]

In this problem, n = 12,  r = 10, p = 0.87 (the 87%).

The probability of exactly 10 made shots out of 12 attempted is

[tex]\binom{12}{10}(0.87)^10(1-0.87)^2 =66(0.87^10)(0.13)^2 \approx 0.2771[/tex]

Angles x° and 157° are neighboring because they share a shared vertex and side, preventing them from overlapping,  the sum of any two angles on a straight line equals 180°.

Two lines converge at a common point to form an angle. They are expressed by the sign ° and are measured in degrees. Acute, right, obtuse, and reflex angles are four crucial types. There are 360° in a circle. Two rays (half-lines) combined into an angle have a single terminal. The latter is known as the vertex of the angle, while the rays are known as its sides, occasionally as its legs, and occasionally as its arms. The vertex of an angle is the point at which all points meet .

given

If two angles' sums are same, they are said to be supplementary.

If two angles' sums are same, they are said to be complimentary.
