Answer:

  -3/2

Step-by-step explanation:

The line crosses grid intersections at (-1, 2), (1, -1) and (3, -4). These points are separated by 2 units horizontally and 3 units vertically.

The rise (vertical change) is -3 for each run (horizontal change) of +2, so the ratio rise/run is -3/2. That is the slope of the line: -3/2.

Answer:

20x+40

Step-by-step explanation:

Hey there! first, we multiply 5 x 4x = 20x. then we multiply 5 x 8 = 40

now we add them but in the 20x there is x so we can't add them but we can write them as 20x + 40

Answer:

[tex]\huge\boxed{\sf{20x+40}}[/tex]

Step-by-step explanation:

Hello.

The Distributive Property states that

a(b+c)=ab+ac [tex]\mapsto[/tex] we multiply a times b and c

Now, simplify the given expression:

5(4x+8)

20x+40

I hope it helps.

Have a great day.

Answer:

-4

Step-by-step explanation:

8x-3=5(2x+1)

8x-3=10x+5

-2x-3=5

-2x=8

x=-4

Answer:

A

[tex]x = - 4[/tex]

Step-by-step explanation:

do the Parentheses first so----

do Parentheses first which would then be 8x-3=10x+5

then put "10x in the middle of 8x and -3

so

[tex]8x - 10x - 3 = 5[/tex]

then 8x-10x which would equal -2x

then you would be left with

[tex] - 2x = 5 + 3[/tex]

add the 5+3 ------>> -2x=8

(divide both sides)

[tex]x = - 4[/tex]

MAKE SURE TO USE UNITS

Answer:

n>1

Step-by-step explanation:

Given

Statement: 4x n is greater than 4

Required

Value of n

First we need to rewrite the statement in algebraic form;

Product 4 * n is represented by 4n

greater than 4 is represented by > 4

Bringing these two together, it gives the following

Divide through by 4

We've arrive at solution;

This means that n is greater than 1

So, the values of n must start from 2 to show that the condition is true

Answer:

Step-by-step explanation:

surface area of a square base pyramid = base area + 4 ( triangular sides area)

where:

base = 12 m

side height length = 9 m

Surface area = 12² + 2(12)9

                     = 144 + 216

                     = 360 m²

Answer:

5

Step-by-step explanation:

(n-2)180 = 108

          n

Distribute

180n-360=108n

-360=-72n

5=n

n=5

Answer:

5 sides

Step-by-step explanation:

Use the formula for the measure of an interior angle of a polygon

[tex]\frac{(n - 2)180}{n}[/tex]

Solve for n (the number of sides):

108 = [tex]\frac{(n - 2)180}{n}[/tex]

108n = (n - 2)180

108n = 180n - 360

-72n = -360

n = 5

So, the polygon has 5 sides.

Answer:

25

Step-by-step explanation:

30 goes into 750 25 times.

You can check your answer by multiplying 30 by 25 which equals 750. Therefore your answer is correct.

The 750 divided by 30 equals 25. This means that if we distribute 750 objects into 30 groups equally, each group would contain 25 objects.

When we divide 750 by 30, we can calculate the result as follows:

750 ÷ 30 = 25

Therefore, 750 divided by 30 equals 25. This means that if we distribute 750 objects into 30 groups equally, each group would contain 25 objects. Division is the arithmetic operation that allows us to determine how many times one number (the divisor) can be subtracted from another number (the dividend) without resulting in a negative value.

In this case, when we divide 750 by 30, we find that the quotient is 25. This represents the number of groups or units we can obtain when dividing 750 into 30 equal parts. Division is a fundamental mathematical operation used in various real-life scenarios, such as distributing resources, calculating averages, and solving ratio problems.

Answer:

4000000

Step-by-step explanation:

thats to the nearest million

Using conversion, the 3887860 tones of paper is converted into 400000 millions.

Conversion is "the process of changing the value one of form to another".

According to the question,

3887860 tones of paper was collected last year. In order to convert to the nearest million.

1 ton = 9,071847 million

3887860 tones = 9,071847 × 3887860

                          = 3.52700711 [tex]e^(13)[/tex]  ≈ 400000

Hence, using conversion, the 3887860 tones of paper is converted into 400000 millions.
