Answer:

Step-by-step explanation:

*Not sure how your teacher wants you to round this, but here is how I do it

All you need to do to find the decimal form of a fraction is to take the numerator and divide it by the denominator :

     2 / 3 = 0.6666666.... and keeps going

              = 0.67

To convert this decimal to percentage just multiply it by 100 :

     0.67 x 100 = 67 %

Answer:

13.3 units (nearest tenth)

Step-by-step explanation:

[tex]\boxed{Distance \: between \: 2 \: points = \sqrt{ {(x1 - x2)}^{2} + {(y1 - y2)}^{2} } }[/tex]

Using the formula above, distance

[tex] = \sqrt{ {[2 - ( - 1)]}^{2} + ( - 9 - 4)^{2} } [/tex]

[tex] = \sqrt{ {(2 + 1)}^{2} + ( - 13) {}^{2} } [/tex]

[tex] = \sqrt{ {3}^{2} + ( - 13) {}^{2} } [/tex]

[tex] = \sqrt{9 + 169} [/tex]

[tex] = \sqrt{178} [/tex]

= 13.3 units (nearest tenth)

x is equal to 2 or -5

y is equal to 1 or 8

Step-by-step explanation:

first put your first equation in a format of y = x + _

here it will be :

[tex]y = - \times + 3[/tex]

now go and substitute this in your second equation. just like the picture. the pictures explain further

Hello there!

We are given the simultaneous equations:

[tex] \displaystyle \large{ \begin{cases} x + y = 3 \\ {x}^{2} - 3y = 1 \end{cases}}[/tex]

There are many methods to solve the equation but the best way for this problem is Substitution Method.

First, we have to isolate one-degree variable. I will choose the first equation to isolate. We are going to isolate y-variable so we can substitute the first equation in the second.

[tex] \displaystyle \large{ \begin{cases} x + y = 3 \\ {x}^{2} - 3y = 1 \end{cases}}[/tex]

Subtract x both sides for first equation.

[tex] \displaystyle \large{ \begin{cases} x - x+ y = 3 - x \\ {x}^{2} - 3y = 1 \end{cases}} \\ \displaystyle \large{ \begin{cases} y = 3 - x \\ {x}^{2} - 3y = 1 \end{cases}}[/tex]

After isolating y-term, we can finally substitute y = 3-x in the second equation.

[tex] \displaystyle \large{ \begin{cases} y = 3 - x \\ {x}^{2} - 3(3 - x) = 1 \end{cases}}[/tex]

Expand -3 in. Recall that negative × negative = positive and negative × positive = negative.

[tex] \displaystyle \large{ \begin{cases} y = 3 - x \\ {x}^{2} -9 + 3x= 1 \end{cases}}[/tex]

Notice that the second equation is in quadratic pattern. We are going to convert in the standard form to solve the equation.

Subtract both sides by 1.

[tex] \displaystyle \large{ \begin{cases} y = 3 - x \\ {x}^{2} -9 - 1 + 3x= 1 - 1 \end{cases}} \\ \displaystyle \large{ \begin{cases} y = 3 - x \\ {x}^{2} -10 + 3x= 0 \end{cases}}[/tex]

Arrange the expression in ax^2+bx+c = 0.

[tex] \displaystyle \large{ \begin{cases} y = 3 - x \\ {x}^{2} -9 - 1 + 3x= 1 - 1 \end{cases}} \\ \displaystyle \large{ \begin{cases} y = 3 - x \\ {x}^{2} + 3x - 10= 0 \end{cases}}[/tex]

Factor the expression.

What two numbers add or subtract each others and equal to 3? (These numbers must not multiply each others and be greater than 10)

What two numbers multiply each others and equal to -10?

Check the number above and multiply two numbers.

Two numbers would be 5 and -2. Factor the expression in two brackets.

[tex] \displaystyle \large{(x + 5)(x - 2) = 0}[/tex]

Then we solve like a linear equation, isolate both x.

[tex] \displaystyle \large{x= - 5,2}[/tex]

We've got two x-values. But we are not done yet.

We are going to use these values to substitute in the simultaneous equation. You can substitute in any equations; the first or second. I will choose to substitute x = -5 or x = 2 in the first equation since it is faster.

[tex] \displaystyle \large{ \begin{cases} y= 3 - x \\ {x}^{2} - 3y = 1 \end{cases}}[/tex]

Substitute x = -5

[tex] \displaystyle \large{ \begin{cases} y= 3 - ( - 5)\\ {x}^{2} - 3y = 1 \end{cases}} \\ \displaystyle \large{ \begin{cases} y= 3 + 5\\ {x}^{2} - 3y = 1 \end{cases}} \\ \displaystyle \large{ \begin{cases} y= 3 - ( - 5)\\ {x}^{2} - 3y = 1 \end{cases}} \\ \displaystyle \large{ \begin{cases} y= 8\\ {x}^{2} - 3y = 1 \end{cases}} [/tex]

When we substitute x = -5, y = 8.

Next, substitute x = 2

[tex] \displaystyle \large{ \begin{cases} y= 3 -2\\ {x}^{2} - 3y = 1 \end{cases}} \\ \displaystyle \large{ \begin{cases} y= 1\\ {x}^{2} - 3y = 1 \end{cases}}[/tex]

When we substitute x = 2, y = 1.

Therefore,

OR

Answer:

-183

Step-by-step explanation:

= −134+(−35)+(−14)

= -134 +(-49)

= -183

The value of the addition the algebraic addition is -183

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division. Finding the sum, or total, of a set of integers is the process of addition in mathematics.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

The algebraic expression will be solved as below:-

E = −134+(−35)+(−14)

E = -134 +(-49)

E = -183

Therefore, the value of the addition the algebraic addition is -183

The perimeter of a triangle is 5.25 inches.

The perimeter of a triangle is defined as the addition of the lengths of the triangle's three sides.

The perimeter of a triangle = sum of all sides

Two triangles are said to be congruent if their corresponding sides and angles are equal.

Given that an equilateral triangle has three congruent that measure 1 3/4 inches on each side.

⇒ [tex]1\dfrac{3}{4} = \dfrac{3+4}{4} = \dfrac{7}{4}[/tex]

Since the perimeter of a triangle is the addition of the lengths of the triangle's three sides.

So the perimeter of a triangle = sum of all sides

The perimeter of a triangle = 7/4 + 7/4 + 7/4

The perimeter of a triangle = 21/4

The perimeter of a triangle = 5.25

Hence, the perimeter of a triangle is 5.25 inches

Answer:

d = 1 7/24 or 31/24;  midpoint would be half of that,or 31/48

Step-by-step explanation:

Since distance is absolute value, add 2/3 and 5/8 to get the entire distance.  Midpoint is that distance divided by 2.

9514 1404 393

Answer:

Step-by-step explanation:

The distance between the points is the difference of their coordinates:

  5/8 -(-2/3) = 15/24 +16/24 = 31/24 = 1 7/24

__

The midpoint is the average of the two coordinates: half their sum.

  (5/8 +(-2/3))/2 = (15/24 -16/24)/2 = (-1/24)(1/2) = -1/48

Answer:

The difference between Shelly's and Terrence's total points

Step-by-step explanation:

The constant is 20. The constant is always on it's own. The variable is x and the coefficient is 90.

If the constant is negative (-), we are assuming that there is a difference. This difference is a comparison. Since Shelly has 90x points and Terrence has 90x - 20. Terrence has less points than Shelly. Terrence has 20 points less (from the expression) and therefore a difference. Since they using Shelly's points (90x) to calculate Terrence points (90x - 20). As you can see both expressions are similar and only the constant makes them unequal, therefore since the constant makes them unequal they are different.
