Answer:
Twice a number increased by five - 2x + 5
Five decreased by twice a number- 5 - 2x
Twice the difference of a number and five- 2(x - 5)
Twice the sum of a number and five= 2(x + 5)
Five subtracted from twice a number= 2x - 5
Twice a number, less five= 2x - 5
Step-by-step explanation:
a. Twice a number increased by 5
Assuming the number as x
Therefore, It's [tex]{{\underline{\textsf{\textbf{2x + 5}}}}}[/tex]
b. Five decreased by twice a number
Assuming the number as x
Therefore, It's [tex]{{\underline{\textsf{\textbf{2x - 5 }}}}}[/tex]
c. twice the difference of a number and five.
Assuming the number as x
Therefore, It's [tex]{{\underline{\textsf{\textbf{2(x - 5)}}}}}[/tex]
d. Twice the sum of a number and five
Assuming the number as x
Therefore, It's [tex]{{\underline{\textsf{\textbf{2(x + 5)}}}}}[/tex]
e. five subtracted from twice a number
Assuming the number as x
Therefore, It's [tex]{{\underline{\textsf{\textbf{ 2x - 5}}}}}[/tex]
f. twice a number, less five
Assuming the number as x
Therefore, It's [tex]{{\underline{\textsf{\textbf{5 - 2x}}}}}[/tex]
Hope it helps!!Sam is framing a closet under a stairway. The stairway is 20 ft 6 in. long, and its angle of elevation is 31º. Find the depth of the closet to the nearest inch.
Answer:
The depth is 127 inches.
Step-by-step explanation:
The stairway and its depth can be compared to a right angled triangle. Let the depth be represented by d.
But,
12 inches = 1 foot
20 ft 6 in = 20 + [tex](\frac{6}{12} )[/tex]
= 20.5 feet
So that applying the appropriate trigonometric function, we have;
Sin θ = [tex]\frac{opposite}{hypotenuse}[/tex]
Sin 31º = [tex]\frac{d}{20.5}[/tex]
d = 20.5 x Sin 31º
= 20.5 x 0.5150
d = 10.5575
d ≅ 11 feet
Therefore,
d = 10.5575 feet = (10.5575 x 12) inches
= 126.69 inches
The depth is 127 inches.

Help me with this I will give you all my points???
Answer:
1. Yes 2. No 3. Yes 4. No
Step-by-step explanation: 1 is a function because none of the x values repeat, 2 isn't a function because in the x coordinates, -2 repeats, 3 is a function because if you were to draw a (vertical) line through each point, none of them have two points on one line, 4 is a function because none of the x coordinates point to more than one y coordinate
A triangle has sides that measure 5 units, 7 units, and 8 units. Is this a right triangle
Answer:
No
Step-by-step explanation:
Using the given lengths if we say this is a right triangle then 8 would be length of hypotenuse
From the Pythagorean theorem
8^2 = 5^2 + 7^2
64 = 25 + 49
64 = 74 is not a correct equation so the triangle is not a right triangle for the given lengths
Sales for the Men’s Suit department last year were $920,000. The manager for the department plans an increase of 9.5% for this year. What is this year’s projected sales volume?
Answer:
The projected sales is $1007400
Step-by-step explanation:
Given
[tex]Sales = \$920000[/tex]
[tex]Increment = 9.5\%[/tex]
Required
Determine the new projected sales
Increment is calculated using:
[tex]Increment = Initial\ Value(1 + Increment\%)[/tex]
In this case:
[tex]Projected\ Sales = Sales(1 + Increment\%)[/tex]
[tex]Projected\ Sales = 920000(1 + 9.5\%)[/tex]
Convert % to decimal
[tex]Projected\ Sales = 920000(1 + 0.095)[/tex]
[tex]Projected\ Sales = 920000*1.095[/tex]
[tex]Projected\ Sales = 1007400[/tex]
Hence, the projected sales is $1007400

Use the distributive property to remove the parentheses.
10(u-2)
Answer:
After using distributive property to remove the parentheses [tex]10(u-2)[/tex] we get [tex]10u-20[/tex]
Step-by-step explanation:
We need to use distributive property to remove the parentheses 10(u-2)
According to distributive property of multiplication over subtraction: [tex]a(b-c)=ab-ac[/tex]
Using the above distributive property to solve the question. Multiply 10 with terms inside the bracket and solving:
[tex]10(u-2)\\=10u-10*2\\=10u-20[/tex]
So, After using distributive property to remove the parentheses [tex]10(u-2)[/tex] we get [tex]10u-20[/tex]

True or false: When a figure on a coordinate grid is translated down and to the right, the vertex with the largest y-coordinate in the pre-image will correspond to the vertex with the largest y-coordinate in the image.(1 point)
Answer:
TrueStep-by-step explanation:
Translation down and to the right doesn't change the dimensions of the original figure.
This will change coordinates of each vertex but the highest coordinates of the pre-image and image will correspond to each other.
A coin is tossed three times. Use this information to solve these problems.1) List the sample space.2) Find the probability of tossing heads exactly twice.3) Find the probability of tossing tails at least twice.
Answer:
1) sample space = {HHH, HHT, HTH, THH, THT, TTH, HTT, TTT}
2) pr(tossing heads exactly twice) = [tex]\frac{3}{8}[/tex]
3) pr(tossing tails at least twice) = [tex]\frac{1}{2}[/tex]
Step-by-step explanation:
In tossing a coin three times, the sample space is the possible outcomes for the number of toss.
So that for the question,
1) The sample space = {HHH, HHT, HTH, THH, THT, TTH, HTT, TTT}
The total number of possible outcome is 8.
2) pr(tossing heads exactly twice) = [tex]\frac{numner of outcome with exactly two heads}{total number of outcome}[/tex]
= [tex]\frac{3}{8}[/tex]
3) pr(tossing tails at least twice) = [tex]\frac{number of outcome with at least two tails}{total number of outcome}[/tex]
= [tex]\frac{4}{8}[/tex]
= [tex]\frac{1}{2}[/tex]

Drag the tiles to the correct boxes to complete the pairs.
Match each division of rational expressions with its quotient.
Answer:
The pairs are:
[tex]\frac{4p^3q}{6p^2q^2}\div \frac{12pq^3}{2p^2q^2}[/tex] => [tex]\frac{p^2}{9q^2}[/tex]
[tex]\frac{10p^3q^3}{2p^2q}\div \frac{5pq}{6pq^2}[/tex] => [tex]6pq^3[/tex]
[tex]\frac{14p^2q^3}{2pq}\div \frac{7p^2q^2}{6p^3q^2}[/tex] => [tex]6p^2q^2[/tex]
[tex]\frac{16pq^3}{24p^2q^3}\div \frac{2p^2q^2}{p^3q^3}[/tex] => [tex]\frac{q}{3}[/tex]
Step-by-step explanation:
We are going to solve the questions one by one and then write the quotients with every question.
In order to calculate the division, the terms are multiplied then exponents are added or subtracted between numerator and denominator to get the simplest form of answer.
First Expression:
[tex]\frac{4p^3q}{6p^2q^2}\div \frac{12pq^3}{2p^2q^2}[/tex]
When two fractions have to be divided the second fraction is reversed i.e. numerator becomes denominator and vice versa.
[tex]= \frac{4p^3q}{6p^2q^2} * \frac{2p^2q^2}{12pq^3}\\=\frac{p^5q^3}{9p^3q^5}\\=\frac{p^2}{9q^2}[/tex]
Second Expression:
[tex]\frac{10p^3q^3}{2p^2q}\div \frac{5pq}{6pq^2}[/tex]
Removing the division symbol
[tex]=\frac{10p^3q^3}{2p^2q} * \frac{6pq^2}{5pq}\\=\frac{6p^4q^5}{p^3q^2}\\=6pq^3[/tex]
Third Expression:
[tex]\frac{14p^2q^3}{2pq}\div \frac{7p^2q^2}{6p^3q^2}[/tex]
Removing the division symbol
[tex]=\frac{14p^2q^3}{2pq} * \frac{6p^3q^2}{7p^2q^2}\\= \frac{6p^5q^5}{p^3q^3}\\= 6p^2q^2[/tex]
Fourth Expression:
[tex]\frac{16pq^3}{24p^2q^3}\div \frac{2p^2q^2}{p^3q^3}[/tex]
Removing the division symbol
[tex]=\frac{16pq^3}{24p^2q^3} * \frac{p^3q^3}{2p^2q^2}\\=\frac{p^4q^6}{3p^4q^5}\\=\frac{q}{3}[/tex]
Hence,
The pairs are:
[tex]\frac{4p^3q}{6p^2q^2}\div \frac{12pq^3}{2p^2q^2}[/tex] => [tex]\frac{p^2}{9q^2}[/tex]
[tex]\frac{10p^3q^3}{2p^2q}\div \frac{5pq}{6pq^2}[/tex] => [tex]6pq^3[/tex]
[tex]\frac{14p^2q^3}{2pq}\div \frac{7p^2q^2}{6p^3q^2}[/tex] => [tex]6p^2q^2[/tex]
[tex]\frac{16pq^3}{24p^2q^3}\div \frac{2p^2q^2}{p^3q^3}[/tex] => [tex]\frac{q}{3}[/tex]

Compute |1-3+5-7+...+13-15|
Answer:
8
Step-by-step explanation:
There are a couple different ways you can solve this, but this is generally the quickest way.
Identify a pattern in the problem. We can see that [tex]1-3=-2[/tex], [tex]5-7=-2[/tex], and so on. Subtracting every two odd numbers (without repeating any numbers) in that problem will always give us the same answer: -2.
So, we see how many pairs of odd numbers there are.
1 and 3, 5 and 7, 9 and 11, 13 and 15. We have four pairs of odd numbers. We can just multiply -2 by 4, which leaves us with an answer of -8.
Finally, since this is also an absolute value equation, the answer will be positive, so the final answer is 8.
