Answer:

1,600

Step-by-step explanation:

When dividing with fractions, remember this rule!!!!

KEEP SWITCH FLIP

- Keep the first fraction

- Switch the sign from division to multiplication

- Flip the second fraction so it becomes its reciprocal (the numerator becomes the denominator and the denominator becomes the numerator)

Let's begin!

640 ÷ 2/5

We know that every number divided by 1 is itself, thus every numerator has an invisible 1 as its denominator. Now we can rewrite it as:

640/1  ÷ 2/5

First, keep 640/1. Then change the ÷ into a ×

640/1 × 2/5

Next, flip the 2/5 so the 5 is on top and 2 is on the bottom

640/1 × 5/2

And multiply across!

640 × 5 = 3,200

1 × 2 = 2

3,200/2 = 1,600

Your answer is 1,600!!

Hope this helps clear things up for you. Let me know if you any other questions :D

Answer: Slope = -7

Concept:

Here, we need to know the formula that helps to find the slope by two points.

The slope of a line is a number that describes both the direction and the steepness of the line.

Slope = Δy / Δx = (y₂ - y₁) / (x₂ - x₁)

Solve:

Given information

(x₁, y₁) = (1, 4)

(x₂, y₂) = (0, 11)

Given expression

Slope = (y₂ - y₁) / (x₂ - x₁)

Substitute values into the expression

Slope = (11 - 4) / (0 - 1)

Simplify the values in the parentheses by subtraction

Slope = (7) / (-1)

Simplify by division

Step-by-step explanation:

Answer: 4/10 + 1/5 = 0.6 and  4/10 - 1/5 = 0.2.

Step-by-step explanation:

1. Convert the fractions into decimals by dividing the numerator(the number to the left or top of the fraction) by the denominator(the number to the right or bottom of the fraction.

2. For the first question, add the two decimals to get your answer. For the second question, you subtract. 0.4-0.2.

Answer:

5/3 or 1.6

Step-by-step explanation:

To solve this, multiply the numerator by 5.

1/3 * 5 = 5/3. We can simplify that into decimal form which is 1.6.

Answer:

1. q = 3

2. w = 9

Step-by-step explanation:

1.

-2q - 5 = -11

Add 5 to both sides:

-2q - 5 + 5 = -11 + 5

-2q = -6

Divide both sides by 2:

-2q ÷ 2 = -6 ÷ 2

-q = -3

Divide both sides by -1:

-q ÷ -1 = -3 ÷ -1

q = 3

2.

w/3 + 2 = 5

Subtract 2 from both sides

w/3 = 3

Multiply both sides by 3:

w = 9

The value of the expression (x² + 3x + 2) × (2x² + 3x - 1) will be 2x⁴ + 9x³ - 12x² + 3x - 2.

When the relevant components and basic processes of a numerical method are given values, the expression's result is the result of the computation it depicts.

The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.

The expression is given below.

⇒ (x² + 3x + 2) × (2x² + 3x + 1)

Simplify the equation, then we have

⇒ (x² + 3x + 2) × (2x² + 3x - 1)

⇒ x²(2x² + 3x - 1) + 3x(2x² + 3x - 1) + 2(2x² + 3x - 1)

⇒ 2x⁴ + 3x³ - x² + 6x³ + 9x² - 3x + 4x² + 6x - 2

⇒ 2x⁴ + 9x³ - 12x² + 3x - 2

The value of the expression (x² + 3x + 2) × (2x² + 3x - 1) will be 2x⁴ + 9x³ - 12x² + 3x - 2.

Answer:

x=2

Step-by-step explanation:

first you distribute the two on the left side of the equation and get 2x+10= -10x+34. Then add 10x to both sides of the equation to get 12x+10=34. Then subtract 10 from both sides of the equation to get 12x=24. finally divide both sides of the equation by 12 and get x=2

Answer:

2x - (x+6)

Step-by-step explanation:

Answer:

Explanation:

The number 43 is basically 40+3

We read "43" as "forty three", in which you can think of having 40 and then an additional 3 on top of that to get 40+3 = 43 overall.

As for the decimal portion, we do the same sort of thing.

The 0.205 breaks up into 0.2 + 0.005

0.2 = 2 tenths

0.005 = 5 thousandths

So that's why 43.205 breaks down into 40+3+0.2+0+0.005; each place value digit corresponds to a term in that expanded sum.
