Answer:

  factors: (x +5) and (2x -1)

  zeros: -5 and 1/2

Step-by-step explanation:

The factorization can be aided by considering the factors of ac=2·(-5) that have a sum of b=9.

  -10 = -1×10 = -2×5

The sums of these factors are ...

  -1+10 = 9 (the pair we want), and -2+5 = 3

This means we can rewrite the function as ...

  g(x) = 2x² +10x -x -5

and factor by grouping.

  g(x) = (2x² +10x) -(x +5)

  g(x) = 2x(x +5) -1(x +5) = (2x -1)(x +5)

The factors of g(x) are (x +5) and (2x -1).

__

The zeros of the function are the values of x that make these factors be zero.

  x+5 = 0   ⇒   x = -5

  2x -1 = 0   ⇒   2x = 1   ⇒   x = 1/2

3:18 - divide 3 into each side

None

Divide like number 1

Switch the numbers and divide

Do the opposite of number 1

Answer:x = 3

because (34x - 2) and (32x + 4) are two opposite angles

=> 34x - 2 = 32x + 4

⇔ 34x - 32x = 4 + 2

⇔ 2x = 6

⇔ x = 3

Answer:

120 m^2

Step-by-step explanation:

Length of the room = 10 m

Breadth of the room = 12 m

We know that, Area = Length * Breadth

Hence,

Total Area of carpet needed to cover the floor of the room = 12 * 10 = 120 m^2

If group of boy scouts are hiking the Appalachian Trail. They determine that they are traveling at a rate of 5 miles every 2 hours. It took 4hrs them to travel 10 miles.

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.

Given,

A group of boy scouts are hiking the Appalachian Trail.

They are traveling at a rate of 5 miles every 2 hours

We need to find how long will it take for them to travel 10 miles at the same rate.

Let x be the required time

5/2=10/x

Apply cross multiplication

5x=20

Divide both sides by 5

x=4

Hence it took for them 4 hours to travel 10 miles of distance

General Formulas and Concepts:

Pre-Algebra

Algebra I

Step-by-step explanation:

Step 1: Define systems

3x + y = 2

4x + 3y = 3

Step 2: Rewrite systems

y = 2 - 3x

4x + 3y = 3

Step 3: Solve for x

Step 4: Solve for y

Step 5: Check

Graph the systems of equations.

Answer:

x = 3/5, y = 1/5

Step-by-step explanation:

Starting with:

3x + y = 2

4x + 3y = 3

Multiplying the first equation by -3:

-9x - 3y = -6

4x + 3y = 3

Adding the equations:

-5x = -3

Simplifying:

x = 3/5

Substituting x = 3/5 into the first equation:

9/5 + y = 2

Subtracting:

y = 1/5

There is 2145.52 cubic inches of air in the ball

Step-by-step explanation:

A round ball is an example is hollow sphere. In order to find how much air the ball holds, the volume of the sphere needs to be found.

Given

Radius = r = 8 in

The volume of sphere is given by:

[tex]V = \frac{4}{3} \pi r^3[/tex]

Putting the values we get

[tex]V = \frac{4}{3} * \frac{22}{7} * (8)^3\\V = \frac{4}{3} * \frac{22}{7} * 512\\V = \frac{45056}{21}\\V = 2145.52\ in^3[/tex]

There is 2145.52 cubic inches of air in the ball

Answer:

He will cover 2,827.433 feet² area of the park with plant food.

Step-by-step explanation:

The diameter of the garden is 60 feet and the radius will be 60 feet/2 = 30 feet.

diameter= 60 feet

radius = diameter/ 2= 60/2= 30 feet

The area of the circle can be found by the formula πr²

Area= πr²=π(30)²

 Area = 900π= 2,827.433 feet²

He will cover 2,827.433 feet² area of the park with plant food.

Answer: It should be division property of equality.

Answer:

Division Property of Equality

Step-by-step explanation:

To solve this problem Remus needs to isolate the variable, which means to get rid of the 7. Since the 7 is being multiplied the opposite operation needs to be used; the opposite of multiplication is division. So each side needs to be divided by 7, the division property of equality tells us that an equation can be divided by anything as long as it is done on both sides. So to solve use the division property of equality to do 7q/7=49/7, which equals q=7 when simplified.

Answer:

50

Step-by-step explanation:

There are 50 candies in the bag.

A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.

Variables are the name given to these symbols because they lack set values.

In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.

Given:

John ate 40% of the candies in a bag.

If John ate 20 candies.

let the total number of Candies be x.

So, 40% of x = 20

40/ 100 x = 20

x = 2000/ 40

x= 50

Hence, there are total 50 Cadies.

0.1x + 0.25y = 5.40

x = number of dimes

y = number of quarters

Therefore,

Total number of coins will be

1 dime = $0.1

1 quarters =$0.25
