Answer:

[tex]t=-5[/tex]

Step-by-step explanation:

Let's solve this equation.

[tex]20=-4t[/tex]

Let's turn it around.

[tex]-4t=20[/tex]

Let's make this into a fraction and divide each side by -4

[tex]\frac{-4t}{-4} =\frac{20}{-4}[/tex]

And the answer is

[tex]t=-5[/tex]

Answer:

v+24

Step-by-step explanation:

I first drew a line with A in one side and C in the other side. Then, I put B in the middle, as it is the midpoint. Under AB, I put 4v, and under AC, I put 5v+24. To get BC, you must subtract 5v+24 and 4v. I did 5v+24-4v. All I really had to do was subtract 4v from 5v which gave me v, since I can only subtract like-term numbers. Anyway, after that, I got v+24. Hope this helped!

Answer:

Step-by-step explanation:

B) the sum is linear and the product is quadratic

D) the sum has one y-intercept and the product has two x-intercepts

The sum is linear and the product is quadratic and The sum has one y-intercept and the product has two x-intercepts are two statements which compare the sum and product

Two or more expressions with an Equal sign is called as Equation.

We need to find the statements which correctly compare the sum and product

The given statements are

1. Both functions have a constant rate of change.

2. The sum is linear and the product is quadratic.

3. The x-intercepts are the same.

4. The sum has one y-intercept and the product has two x-intercepts.

5. Both functions decrease for x > 2

A linear function simply means a function that represents a straight line on the coordinate plane.

In this case, the sum is linear and the product is quadratic while the sum has one y-intercept and the product has two x-intercepts.

Hence, the sum is linear and the product is quadratic and The sum has one y-intercept and the product has two x-intercepts are two statements which compare the sum and product

Answer:

89

Step-by-step explanation:

There are only 30 pages but last page number is 89.

The last page of the book would be with the number 89. For details, check the calculations below.

The number system is characterized as the arrangement or sequence in which the numbers are arranged in a mathematical order beginning from 0 in whole numbers.

In the given situation,

We know that,

Total pages available in the book = 30

And every third page is omitted from the book due to misprinting of the page numbers.

If we divided 90/3 = 30 pages are there. Hence, the last page would be 89 itself.

Thus, the above response is correct.

Answer:

22/3

Step-by-step explanation:

First, I multiplied 7 and 3 because 7 is the whole number and 3 is the denominator of the fraction.

7*3=21

Then, I added 21 to 1 because 1 is the numerator in the fraction.

21+1=22

Finally, I made it 22/3 because the denominator of the fraction is 3.

So, your final answer is 22/3.

[tex]$7\frac{1}{3}[/tex] as a improper fraction can be written as 22/3.

Given is to write 7 1/3 as a improper fraction.

An improper fraction is a fraction where the numerator is greater than or equal to the denominator. We can write that for a fraction {x/y} to be improper, the following conditions should be fulfilled -

{x} > {y}

or

{x} ≥ {y}

We can write 7 1/3 as a improper fraction as -

[tex]$7\frac{1}{3}[/tex] = [tex](3\times7+1)/3[/tex] = [tex]$\frac{22}{3}[/tex]

Therefore, [tex]$7\frac{1}{3}[/tex] as a improper fraction can be written as [tex]$\frac{22}{3}[/tex].

Answer: The slope of the line is -2/3.

Step-by-step explanation:

How I think of it is that on the y plane on a graph, going from positive 1 to negative 1 you need to move down 2 places and thats the "rise" part of rise over run eventhough you moved down. Then on the x plane, going from 0 to 3 you need to move 3 spaces to the right on the graph and thats the "run" part of rise over run because you can either move left or right. Rise over run can also be thought of as change in y over change in x which means that since i went down 2 places on the y, the change in y was 2 and since we moved 3 places over on the x plane the change in x whould be 3. Since we move down and then to the right on the graph, the line being created would be negative, so you final answer for the slope is -2/3!

Answer:

970 cm

Step-by-step explanation:

Given that:

Size of brick :

25cm × 16cm × 10cm

Number of bricks = 4700

Dimension of wall = 20 m long × 20 cm wide

Let the height = h

Hence, dimension of wall (length and height)

2000 cm × h

Dimension of window = 2m × 1.5m = 200cm × 150cm

Number of windows = 2

Total area covered by windows = 2 * (L * B)

= 2(200 * 150) = 60,000cm

Brick = (25 * 16) * 4700 = 1, 880, 000 cm ( length and height)

Wall = 2000 * height - 60,000 = 1880000

2000height - 60,000 = 1880000

2000height = 1880000 + 60,000

2000height = 1940000

Height = 1940000 / 2000

Height of wall = 970 cm

Answer:

Every inch is 2.54 cm, so 29.5 in=74.93 cm. 74.93 rounded to the nearest whole is 75cm.

Answer:

75 cm

Step-by-step explanation:

Answer: W * L = 120

2W + 2L = 44

2W = 44 - 2L

W = 22 - L

(22-L) * L = 120

22L - L² = 120

L² - 22L = -120

L² - 22L + 121 = 121 - 120

(L - 11)² = 1

L - 11 = ±1

L = 11 ± 1

L = 10 or 12

Answer: The expression x(x + 1) is even for any integer x (since either x or x + 1 is even). So this says that 5 × even + 1 = even, or odd = even. Since there is no integer that is both even and odd, we have reached a contradiction and √5 is irrational. So the answer would be D.) because it cannot be expressed as a ratio of integers

A) x(x-4)(x-1)/2(x+4)

Step-by-step explanation:

(x²-16)/(2x+8) * (x³-2x²+x)/(x²+3x-4)

factor

(x+4)(x-4)/2(x+4) * x(x-1)(x-1)/(x+4)(x-1)

You can take out both (x+4) from the first side, and both (x-1) on the second side.  Then you’re left with:

(x-4)/2 * x(x-1)/(x+4)

which equal

x(x-4)(x-1)/2(x+4)

which is A.
