In what ways is it useful to develop an algorithm for adding and subtracting rational numbers?

Answers

Answer:

To add or subtract these rational numbers, you first need to change your rational numbers so that they share a common denominator. Once you have a common denominator, you can then go ahead with the addition or subtraction of just the numerator part

Step-by-step explanation:

The algorithm is shown below

What is Algorithm?

An algorithm in math is a procedure, a description of a set of steps that can be used to solve a mathematical computation.

For example, a step-by-step procedure used in long divisions is a common example of a mathematical algorithm.

To add or subtract these rational numbers,

First make sure that both the rational number must have same  denominator.

After that having common denominator proceed with subtraction or addition.

The subtraction or addition only be performed with numerator not with denominator.

Answer:

For the first one, you get x<7.

For the second one, you get x >_ 11

Step-by-step explanation:

For the first one: -2x - 2 > -16

Step 1. Add 2 to both sides.

-2x - 2 +2 > -16 + 2

-2x > -14

Step 2. Divide both sides by -2 and switch the sign

-2x/-2 > -14/-2

x < 7

For the second one: 2x - 1 >_ 21

Step 1: Add 1 to both sides

2x -1 +1 >_ 21 + 1

2x >_ 22

Step 2: Divide both sides by 2

2x/2 >_ 22/2

x >_ 11

The new coordinates of the point will be (7, 8)

What are coordinates?

A pair of numbers called coordinates are used to locate a point or a form in a two-dimensional plane. The x-coordinate and the y-coordinate are two numbers that define a point's location on a 2D plane.

Given, the new position of the given point (7, 4) has been achieved after the translation of 4 units up

Since translation upward in the cartesian plane means it is moving along the y-axis and hence its y-coordinate is changed. So, if a point is translated units up, its y-coordinate increases by a unit, and for a point (x,y), it changes to (x,y+a)

Thus,

The new coordinates of the point will be = (7, 4 + 4)

The new coordinates of the point will be = (7, 8)

find x and y if p || q and m3=(4x+6y),m5=86,and m6=(5x+6y)

Answers

Answer:

(8, 9)

Step-by-step explanation:

3 and 5 are vertical angles and are equal as per definition of vertical angles

4x + 6y = 86

5 and 6 are supplementary angles and sum up to 180 as per definition of supplementary angles

5x + 6y + 86 = 180 ⇒ 5x + 6y = 94

Comparing the two equations

6y = 86 - 4x and 6y = 94 - 5x86 - 4x = 94 - 5x5x - 4x = 94 - 86x = 8

What would be your next step?
14p - 8 = 22 + 20p
-8 = 22 + 6p

Answers

to subtract 22 from both sides, then the 6p after! hope that helped :))

The next step to solve the equation is subtracting 22 from both sides.

Thus, option (B) is correct.

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

Given equation: -8 = 22 + 6p.

1. Start by isolating the variable term, 6p, on one side of the equation.

In this case, subtracting 22 from both sides of the equation:

  -8 - 22 = 22 + 6p - 22

  -30 = 6p

2. Next, divide both sides of the equation by 6 to solve for p:

  -30/6 = 6p/6

  -5 = p

Therefore, the solution to the equation is p = -5.

Thus, option (B) is correct.

5. Give the x-intercept from standard form (remember, let y=0)

Answers

Answer:

The slope of the line is  m = −11/3 ≈ −3.66666666666667 .

Step-by-step explanation:

The slope of a line passing through two points P=(x1,y1) and Q=(x2,y2) is given by m=y2−y1x2−x1.

We have that x1=−6, y1=7, x2=−3, y2=−4.

Plug the given values into the formula for a slope: m=−4−(7)−3−(−6)=−113.

Now, the y-intercept is b=y1−mx1 (or b=y2−mx2, the result is the same).

b=7−(−113)(−6)=−15

Finally, the equation of the line can be written in the form y=b+mx:

y=−15−11x3

The dimensions of a rectangular dining room are 18 feet by 16 feet. If a scale factor of One-fourth is used to make a scale model of the dining room, what is the area of the dining room in the scale model?
18 square feet
36 square feet
48 square feet
72 square feet

Answers

Given -

The dimensions of a rectangular dining room are 18 feet by 16 feet. i.e, length (l) = 18 feet and breadth (b) = 16 feetScale factor of One-fourth is used to make a scale model of the dining room.

To find -

the area of the dining room in the scale model (A)

Solution -

As we know, the area of rectangle = length of the rectangle × breadth of the rectangle

To state the dimensions of the scale model we will multiply 1/4 with the already given dimensions of a rectangular dining room. Hence, dimensions of scale model is 18/4 by 16/4.

Now,

Area = length × breadth

Area = 18/4 × 16/4 square feet

Area = 18 square feet

Therefore, the area of the dining room in the scale model (A) is 18 square feet.

Answer:

18 square feet

Step-by-step explanation:

lets call the shortest side x.

that means the second side is 3x

the third side is x + 5

the perimeter of the triangle is 95 inches.

using this information, you can make the following equation:

x + 3x + x + 5 = 95

subtract 5 from both sides.

x + 3x + x = 90

5x = 90

x = 18

the shortest side is 18 inches long
