1). x2 = 121
2). 4x? = 20
3). 4x² + 5 = 20

Answer:

The largest is -5

Step-by-step explanation:

This is because when dealing with negatives, the closer to the zero, the larger the number.

Answer:

-5

Step-by-step explanation:

-5, because numbers that are closer to zero are larger than others that are farther away from 0.

These are the numbers in order from least to greatest: -15, -12, -11, -9, -5

Answer: I think it's 662.4

Please correct me if I'm wrong.

Answer:

The distance Maria walked is 75 ft.

Total displacement from her starting point is 35 ft east.

Step-by-step explanation:

Consider the sketch below.

The distance travelled can be obtained by adding all the distances walked in different directions.

This is 20ft +35 ft +20ft = 75ft

The distance Maria walked is 75 ft.

The displacement of an object refers to the distance travelled in a specified direction.

We noticed that maria moved 20ft north, then 35 ft east, only to come back 20 ft south again.

This means her total displacement from her starting point is 35 ft east. this is because her north and south movements cancelled out each other.

Answer:

x = 1.5

Step-by-step explanation:

First, we distribute (get rid of parentheses):

6x - 3 - 3x = 5 - x - 2

Then, we simplify:

3x - 3 = 3 - x

Then, we combine like terms:

3x + x = 3 + 3

Then, we simplify again:

4x + 6

Finally, we divide 4 on both sides:

We got x = 1.5

Hope this helps!

Answer:

X = 1.5

Answer:

75/99

Step-by-step explanation:

Do you mean

 0.757575... = 0.75 = ?

If so, consider this:

        x =  0.757575...

     100x = 75.757575...

 100x - x = 75

      99x = 75

        x = 75/99

Answer:

no solution

Step-by-step explanation:

start by

distributing the 2 on the right side of the equation

you should get 4n-9=10+4n

then you should try to combine like terms, start by subtracting the 4n on the left side from the one on the right

both of those should cancel out

leaving you with -9=10, which is obviously false, meaning there is no solution

I think it’s no solution.

Answer:

  A) 10

  B) 39

  C) the last digit must be greater than the previous digit. 0 is not greater than any other digit, so the last digit cannot be 0.

Step-by-step explanation:

A) Numbers of the form low, high, ... can start with digits 1 or 2, and the 3rd digit will be the other one. There 4 such numbers 1423, 1324, 2413, 2314. In addition, For a first digit of 2, the second digit may be 1, allowing 2143. Thus, there are 5 numbers starting with 1 or 2 and ending with 3 or 4.

There are 5 additional numbers that are the reverse of these.

  There are 10 4-digit snake-like numbers containing 1–4 exactly once.

__

B) We assume a "3-digit number" will be in the range 100–999. That is, the leading digit will not be zero. If you allow a leading 0, the answer is different.

With 6 as a middle digit, the numbers 1–5 can be the first digit and the numbers 0–5 can be the last digit. Hence there are 5·6 = 30 numbers of the form low-6-low.

If the form is high-6-high, there are 3 possible first digits and 3 possible last digits, so 3·3 = 9 numbers of the form high-6-high.

  There are 39 3-digit snake-like numbers with 6 as the middle digit.

__

C) A 7-digit snake-like number will alternate high-low, with high being the last digit. Hence the last digit must be higher than the previous digit, so cannot be 0.

Answer:

1. The relationship is proportional.

2. The cost for 30 roses is 90 dollars.

Step-by-step explanation:

1. The price (y) divided by the number of roses (x) equals 3, no matter what section in the table you try it on; y/x = 3. This means that the relationship is proportional.

Another way to explain this is x * 3 = y. For example, 3 roses * $3 = $9

2. We know that one rose costs $3. So you can multiply:

30 roses * $3 = $90

2(1/2 A + N = d)

A + 2N = 2d

A = 2d - 2N

Answer:

A = 2(d - N)

Step-by-step explanation:

Given

[tex]\frac{1}{2}[/tex] A + N = d ( subtract N from both sides )

[tex]\frac{1}{2}[/tex] A = d - N ( multiply both sides by 2 to clear the fraction )

A = 2(d - N)

With the advent and proliferation of the use of computers, data can now be analyzed with the aid of spreadsheets. These spreadsheets such as the one found in Microsoft Excel are arranged in grids whereby, the rows are numbered and the columns are identified with alphabets. The data entered in the spreadsheet are guided by formulas which can be found on the formula tool bar.

The formula gives an insight into the calculation performed for the list of items provided in the grid. There are several mathematical functions that aid in the calculations, such as the SUM and DIV functions.

Answer:

$2.040

Step-by-step explanation:

Para calcular la cantidad que fue abonada en realidad, debes encontrar el valor del descuento calculando el 15% del valor total de la compra y este resultado se debe restar del total:

$2.400*15%= $360

$2.400-$360= $2.040

De acuerdo a esto, la cantidad abonada en realidad es: $2.040.

Answer:

42 units

Step-by-step explanation:

If R is the midpoint of QS, then by definition, QR = RS. Since QR = 8x - 51 and RS = 3x - 6, set these equal to solve for x:

QR = RS

8x - 51 = 3x - 6

5x = 45

x = 9

Now that we know x = 9, we can plug this back into one of the expressions for QR or RS to find its length:

QR = 8x - 51 = 8 * 9 - 51 = 72 - 51 = 21

Since half of QS is 21, then the whole of QS is twice that:

2 * 21 = 42

The answer is thus 42 units.

Answer:

Associative states you can regroup numbers and you will get the same answer and the commutative property states that you can move numbers around and still have the same answer.

Example:

Commutative a+b=b+a

Associative a+ (b+c) = (a+b) +c= a+b+c

The equation that represents the scenario is 540 = 30(30 - x)

A rectangle is a 2-D shape with 4 sides.The formula for calculating the area of the rectangle is expressed as:

A =lw

where:

l is the length

w is the width

Given the following parameters

l = 30ft
w = 30 - x

A = 540

Substitute

540 = 30(30 - x)

Hence the equation that represents the scenario is 540 = 30(30 - x)
