Answer:
[tex]u<-1\text{ or } u>2[/tex]
Step-by-step explanation:
So we have the equation:
[tex]-3|2-4u|+5<-13[/tex]
First, subtract -5 from both sides:
[tex]-3|2-4u|<-18[/tex]
Divide both sides by -3. Since we are dividing by a negative, we will flip the sign:
[tex]|2-4u|>6[/tex]
Definition of absolute value:
[tex]2-4u>6\text{ or } 2-4u<-6[/tex]
Note that we flip the sign on the right because we multiplied 6 by a negative.
On both the left and right, subtract 2:
[tex]-4u>4\text{ or } -4u<-8[/tex]
Divide both equations by -4. Since we're dividing by a negative, flip the signs:
[tex]u<-1\text{ or } u>2[/tex]
So, our final solution is:
[tex]u<-1\text{ or } u>2[/tex]
And we're done!

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 )

4-Fui al supermercado y había un descuento del 15% en el total de la compra, si pagaba en efectivo. Gasté $ 2.400. ¿Qué cantidad aboné en realidad?
Answers
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.

HAS TO BE DONE BY TOMORROW - A positive integer is called snakelike if its digits alternately increase and decrease or vice versa. For example, 130 and 91727 are snakelike. However 123 is not snakelike (2 is greater than 1 but not 3) and 91727 is not snakelike (7 is greater than 1 but not 7)
A) How many 4-digit snakelike numbers contain each of the digit 1,2,3,4 exactly once
B) How many 3-Digit snakelike numbers have 6 as their middle digit
C) a 7-digit snakelike number starts with digit 9. Explain why it last digit cannot be 0
Answers
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.

Step-by-step explanation:
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.

Maria is trying to meet her friends at the pool but construction is blocking her path from the parking lot directly to the pool. Because of this, she has to walk 20 ft north, 35 ft east, and then 20 ft south to get to the pool. Find her distance and displacement
Answers
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.

The table below shows the price, in dollars, for the number of Rose's indicated.
Answers
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

If the area of the yard is 540 square feet, how many feet shorter than the length is the width? A yard with a length of 30 feet and a width of (30 minus x) feet. Which equation represents the scenario? 30 + (30 – x) = 540 540 – 30 = 30 – x 30(30 – x) = 540 540 – (30 – x) = 30 : Please Help

Answer:
I got this answer from the comments and it was correct so the correct answer is C.
Step-by-step explanation:
Ty cco713.
The equation that represents the scenario is 540 = 30(30 - x)
Area of a rectangleA 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)

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

If R is the midpoint of QS, QR = 8x – 51 and RS = 3x – 6, find QS.
Answers
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.

Step-by-step explanation:
First, we distribute (get rid of parentheses):

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
