Answer:
x-1
Step-by-step explanation:
Answer:
x - 1
Step-by-step explanation:
4(x+5)-3(7+x)
4( x + 5) = 4x + 20
4x+20-3(7+x)
-3(7 + x) = -21 - 3x
4x+20-21-3x
4x + 20 - 21 - 3x = x-1
simplify this (0.001)^3.
Answer:
0.003

Five friends attend a matinee movie and spend $8 per ticket. They also purchase a small bag of popcorn each. The friends spend a total of $62.50. Let x be the price of a small bag of popcorn.
i dont know the answer can you help
Step-by-step explanation:
so each ticket is $8 so thats going to be 8x.There are 5 friends so you pay for 5 tickets they buy small bag of popcorn so let that have a variable of.p. then they spend a total of 62.50.
62.50=8(5)+p
62.50=40+p
-40. -40
22.50=p
so the 5 small bags of popcorn costs $22.50
Decide whether or not the relation is a function.
[(0,1), (-5,4), (0,2), (5,-4)]
Answer:
The relation {(0,1), (-5,4), (0,2), (5,-4)} does NOT represent the relation.
Step-by-step explanation:
We know that a function is a relation where each input or x-value of the X set has a unique y-value or output of the Y set.
In other words, we can not have duplicated inputs as there should be only 1 output for each input.
Given the relation
{(0,1), (-5,4), (0,2), (5,-4)}
From the given relation is clear that the input value x = 0 is repeated twice.
In other words, the input value x = 0 is duplicated.
As we have already mentioned that we can not have duplicated inputs as there should be only 1 output for each input.
Therefore, the relation {(0,1), (-5,4), (0,2), (5,-4)} does NOT represent the relation.

D 35
Answer:
D 35
Step-by-step explanation:
When figuring this out you can just plug in your answers if you want to take it the easier way by just putting in the 35 in places of x and multiplying 0.1 times 35 gets you 3.5 so 3.5 minus 2.5 is 1

The price, P, of a sweater was discounted by 10% in
February. Because the sweater did not sell by the end of
the winter season, it was discounted by another 20% in
March. In terms of P, what was the price of the sweater
after the discount in March?
Answer:
In terms of P, the price of the sweater after the discount is 0.72P.
Step-by-step explanation:
Since the price P would represent 100% and the price was discounted by 10%, you can calculate 10% of 100% and subtract that amount, which would be:
100*10%=10
100-10=90%
This means that the price paid would be 90% of P. Then, the statement says that the price was discounted by another 20%. So, you have to calculate 20% of the price and subtract that amount from the price:
90*20%=18
90-18=72%
According to this, this means that in terms of P, the price of the sweater after the discount is 0.72P.

Taylor charges $15 for the first hour of dog walking and $10 for each additional hour or fraction of an hour. The rates that Lucy charges for x hours of dog walking are modeled with the function shown.
f(x) = LaTeX: \lbrace{LaTeX: \begin{matrix}\text{20x, 0 ≤ x ≤ 2}\\\text{10x, 2 4}\end{matrix}20x, 0 ≤ x ≤ 2 10x, 2 4
Who will charge more to walk a dog for 2.5 hours, Taylor or Lucy? How much more?
Who?:
How much more?:
Answer:
Taylor will charge more by $15
Step-by-step explanation:
Given
Taylor
First Hour = $15
Hourly Rate = $10
Lucy:
[tex]f(x) = \left \{ {{20x,\ 0 \le \ x \ \le 2} \atop {10x, x>2}} \right.[/tex]
For a dog walk of 2.5 hours.
Taylor's charges is:
[tex]Charges = First\ Hour + Hourly\ Rate * 2.5[/tex]
[tex]Charges = \$15 + \$10 * 2.5[/tex]
[tex]Charges = \$15 + \$25[/tex]
[tex]Charges = \$40[/tex]
Lucy's charges is:
Here, we consider
[tex]f(x) = 10x[/tex] Because [tex]x > 2[/tex]
i.e 2.5 > 2
So, Lucy's charges is:
[tex]Charges = 10 * \$2.5[/tex]
[tex]Charges = \$25[/tex]
By comparison;
Taylor will charge more by $15
The difference is calculated by:
[tex]Difference = \$40 - \$25[/tex]
[tex]Difference = \$15[/tex]

(one of those fraction is not equivalent to
[tex] \frac{1}{3} [/tex] )
Answer:
5/18 is not equivalent to 1/3.
Step-by-step explanation:
9/27, 2/6 and 15/45 are equivalent to 1/3.

Which of these is the standard form of the following function?
f(x) = -9(x + 5)2 + 4
f(x) = 9x2 − 90x − 221
f(x) = -9x2 − 90x − 221
f(x) = 9x2 − 180x + 221
f(x) = -9x2 − 180x − 221
Answer:
the answer is B) -9x2 -90x -221

32 feet long and 6 yards wide what is the perimeter in feet
Answer:
100
Step-by-step explanation:
1 yard = 3 feet
6 yards = 18 feet
(18*2)+(32*2)
36+64
100
Answer: The perimeter is a 100 feet.
Step-by-step explanation:
If it is 32 feet long and 6 yards wide then I am thinking that the shape will be a rectangle.
To find the shape of a rectangle, you can use the formula, P = 2l+2w were P is the perimeter, l is the length, and w is the width.
But first since feet and yards are different measurements, and the question is asking for the perimeter in feet, then you will first have to convert 6 yards to feet.
6 yards = 18 feet
This means that the sides will be 32 feet long and 18 feet wide.
Now using the formula, input 32 for L and 18 for W and solve for P the perimeter.
P = 2(32) + 2(18)
P = 64+ 36
P = 100

24. Paul's car holds a maximum of 19 gallons of gas. About how many
liters of gas does Paul need to fill his gas tank?
no
Answer:
71.915
Step-by-step explanation:
3.785= how many liters that are in a gallon X 19= gallons of gas needed to fill the tank
The number of liters in 1 gallon is 3.78541 therefore,71.92 liters Paul needs to fill in his tank.
What is unit conversion?To convert any unit into another is called a unit conversion.
In order to convert units, we need to care about their dimensions their dimension should not be changed.
Given that,
The amount of fuel Paul's car holds = 19 gallons.
We know that,
1 gallon = 3.78541 liter
Multiply both sides by 19
19 gallon = 71.92 liter.
Hence "The number of liters in 1 gallon is 3.78541 therefore,71.92 liters Paul needs to fill in his tank".
