Answer:

6x - 2 - 3x + 4

I think that would be it. I just multiplyed 2 by 3 and then 2 by - 1.

Edit:

The true answer would be 3x+2

The ratio is equivalent to 3:18 is 7:42.

A ratio is a comparison between two amounts that is calculated by dividing one amount by the other. The quotient a/b is referred to as the ratio between a and b if a and b are two values of the same kind and with the same units, such that b is not equal to 0. Ratios are represented by the colon symbol (:). As a result, the ratio a/b has no units and is represented by the notation a: b.

Given:

Ratio = 3:18

         = 1: 6

1. 6:21

= 3:7

2. 5:20

= 1:4

3. 7:42

= 1:6

4. 12:2

= 6:1

Hence, the ratio is equivalent to 3:18 is 7:42.

Answer:

Step-by-step explanation:

did it on ttm

Question 1)

The expression:

11 more than one third of a number

Lets split this is up into parts to make it easier

"11", "more", "one third", "of a", "number"

Lets form the expression for each part,

"11" = 11

"more" = +

"one third" = 1/3

"of a" = *

"number" = n

That forms

11 + (1/3) * n or (1/3) * n + 11

Therefore the answer is D) (1/3)n + 11

Question 2)

Equation,

[tex]\frac{6+5*3}{2+1} = 11[/tex]

Left Hand Side

=[tex]\frac{6 + 15}{3}[/tex]                      (multiplication is first then addition)

=[tex]\frac{21}{3}[/tex]

= 7

7  [tex]\neq[/tex] 11

So, Left Hand Side [tex]\neq[/tex] Right Hand Side

Therefore the answer is false

Answer:

(-3)^2

Step-by-step explanation:

You add 7 on both sides, giving you x^2 - 6x = 7

Then, take half of b, and square it. Giving you x^2 - 6x +(-3)^2 = 7

The answer will be (-3)^2 for this question, but this is not the full solution.

Step-by-step explanation:

because that is the correct answer

4 divided by 0.8 is equal to 5.

To divide 4 by 0.8 using place value, you can follow these way

Convert the decimal divisor, 0.8, into a whole number by multiplying both the tip and the divisor by a power of 10.

Since there's only one decimal place in0.8, you can multiply both figures by 10 to exclude the decimal

0.4 x  10 = 40( multiplying the tip by 10)

0.8 x 10 = 8( multiplying the divisor by 10)

Now we've the division problem as 40 divided by 8.

Divide the converted tip by the converted divisor

= 40 ÷ 8

= 5

Thus, 4 divided by 0.8 is equal to 5.

Answer:

AB ≈ 1095 yards

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

AB² + BS² = AS²

AB² + 1300² = 1700²

AB² + 1690000 = 2890000 ( subtract 1690000 from both sides )

AB² = 1200000 ( take the square root of both sides )

AB = [tex]\sqrt{1200000}[/tex] ≈ 1095 yd ( to the nearest yard )

Answer:

Step-by-step explanation:

a) Let's [tex]x[/tex] the length of the side of the small square.

Thus,

[tex]x^{2} + (\sqrt{40})^2 = (\sqrt{50})^2[/tex]

[tex]x^{2} + 40 = 50[/tex]

[tex]x^{2} = 50 - 40[/tex]

[tex]x^{2} = 10[/tex]

[tex]x = \sqrt{10}[/tex]

[tex]x=3.16[/tex]

b) Now, the area of the small square is

[tex]A= x^{2}[/tex]

[tex]A=(3.16)^2[/tex]

[tex]A=9.99[/tex]

9514 1404 393

Answer:

Step-by-step explanation:

The Pythagorean theorem (see Hint) tells you the length of the hypotenuse (c) is ...

  c² = 1² + 1² = 2

  c = √2 ≈ 1.4142136 . . . units

The estimated value of the length of the hypotenuse is 1.41 units.

__

Of course the shaded square will have an area that is the square of that value:

  area = s² ≈ 1.41² ≈ 1.99 . . . . . rounded to hundredths

The estimated area of the square is 1.99 square units.

__

Additional comment

Of course, we don't have to estimate. We can use the exact value of the side length to determine the shaded square has an area of ...

  area = s² = (√2)² = 2 . . . . exactly

We can also get there by recognizing that the lengths of 1 represent half the length of each of the diagonals of the square. That is, the square's diagonals are both of length 2. The area is half their product, so is (1/2)(2·2) = 2 square units.

Answer:

15/2

Step-by-step explanation:

5 3/4 - 1/6x = 4 1/2

move the variable to it's own side.

5 3/4 - 4 1/2 = 1/6x

change the subtracting side to have common denominators

5 3/4 - 4 2/4 = 1/6x

1 1/4 = 1/6 x

divide both sides by 1/6, same thing as multiplying both sides by 6 (reciprocal)

30/4 = x

reduce: 15/2 = x

The value of x should be 15/2.

Since

5 3/4 - 1/6x = 4 1/2

So, it can be like

5 3/4 - 4 1/2 = 1/6x

Now

5 3/4 - 4 2/4 = 1/6x

1 1/4 = 1/6 x

Now we have to divide both sides by 1/6

So,

30/4 = x

x = 15/2

The rate of change is -300 meters per minute

Step-by-step explanation:

Here, we want to get the rate of change for the given situation

Firstly, we will need to collate the points

Let us have the points as:

(time, height)

The points are;

(10,4500) and (15,3000)

The formula for the slope m representing the average rate of change is;

m = (y2-y1)/(x2-x1)

m = (3000-4500)/(15-10) = -1500/5 = -300 meters/minutes
