The length of a rectangle is twice its width. The perimeter of the rectangle is 121 feet.
Plzzz help
Answer:
[tex]121=6w[/tex]
Step-by-step explanation:
Formula for perimeter of a rectangle:
[tex]P=2l+2w[/tex]
[tex]w[/tex] = width
[tex]l[/tex] = length
Since the length is twice the width,
[tex]l=2w[/tex].
So, plugging these values into the formula, as well as the given perimeter of 121 feet, we get,
[tex]121 = 2(2w)+2w[/tex]
And after some simplification, we are left with,
[tex]121 = 6w[/tex]

x/7+x-2/14=1/7
Please answer x as a fraction!
Answer:
x = [tex]\frac{1}{4}[/tex]
Step-by-step explanation:
Given
[tex]\frac{x}{7}[/tex] + x - [tex]\frac{2}{14}[/tex] = [tex]\frac{1}{7}[/tex]
Multiply through by 14 to clear the fractions
2x + 14x - 2 = 2 ( add 2 to both sides )
16x = 4 ( divide both sides by 16 )
x = [tex]\frac{4}{16}[/tex] = [tex]\frac{1}{4}[/tex]

Producing a musical cost $88,000 plus $5,900 per performance. One sold-out performance earns $7,500 in revenue. If every performance sells out, how many performances are needed to break even? ( solving and writing Mulit-step equation question)
Answer:
55 performances
Step-by-step explanation:
The first equation will be the total cost. The total cost has $88,000 already and then $5,900 is added with each performance. So the equation would be 88,000+5,900x because x will represent the number of performances.
y = 88,000 + 5,900x
The next equation will be how much the performances earn. If they earn $7,500 with each performance then the equation will be 7,500x, with x representing the number of performances
y = 7,500x
Now set the equations equal to each other and solve for x
7,500x = 88,000 + 5,900x
1,600x = 88,000
x = 55
They need to have 55 performances for the cost and the revenue to break even.

Write the equation of the parabola in vertex form.
vertex (0,3), point (1,-4)
f(x) =
Answer:
f(x) = 7x² + 3Step-by-step explanation:
vertex form of an equation of the parabola:
f(x) = a(x - p)² + q
vertex (0, 3) ⇒ p = 0, q = 3
so:
f(x) = a(x - 0)² + 3
f(x) = ax² + 3
the parabola goes through point (1, -4) ⇒ x=1, f(x)=-4
-4 = a(1)² + 3
-4 = a + 3
a = 7
Therefore the equation of the parabola in vertex form:
f(x) = 7x² + 3
Which is a greater y-intercept (0,-1) or (0,-2)
Answer:
(0,-1)
Step-by-step explanation:
-1 is less than -2 so -1 have a greater value since it is closer to the origin (0,0)

like terms and unlike terms
Answer:
In algebra, like terms are terms that have the same variables and powers. The coefficients do not need to match.
Unlike terms are two or more terms that are not like terms, i.e. they do not have the same variables or powers. The order of the variables does not matter unless there is a power. For example, 8xyz2 and −5xyz2 are like terms because they have the same variables and power while 3abc and 3ghi are unlike terms because they have different variables. Since the coefficient doesn't affect likeness, all
Answer:
unlike terms

New York City is a popular field trip destination. This year the senior class at High School A and the senior class at High School B both planned trips there. The senior class at High School A rented and filled 3 vans and 14 buses with 509 students. High School B rented and filled 12 vans and 10 buses with 472 students. Each van and each bus carried the same number of students. Find the number of students in each van and in each bus.
Answer:
Step-by-step explanation:
Let's say :
v = number students in van, b = number of students in bus
From the info provided in the question:
High school A takes 3 vans and 14 buses for 509 students
We can write this as:
3v + 14b = 509
You can re-write this as :
3v = 509 - 14b
We also know High School B takes 12 vans and 10 buses for 472 students:
12v + 10b = 472
Since we already know that 3v = 509 - 14b , substitute this equation into the above formula and you get:
12v + 10b = 472
4(509 - 14b) + 10b = 472
2036 - 56b + 10b = 472
2036 - 46b = 472
2036 - 472 = 46b
1564 = 46b
Divide both sides by 46 to find "b".
b = 1564/ 46 = 34
Therefore the number of students that fit in each bus is 34.
So since we know b = 34, substitute b into the equation at the top:
3v = 509 - 14b
3v = 509 - 14(34)
3v = 509 - 476 = 33
Divide both sides by 3 to find "v".
v = 33/3 = 11.
Therefore the number of students in each van is 11.

Xavier has a savings account with a balance of $320 and deposits(adds money
into account) $12 per month. Dayuan has a savings account with a balance of
$266 and deposits $30 per month.
write the inequality to determine the number of months xavier's account balance will greater than dayuans account balance
Answer:
320 + 12h > 266 + 30h
Step-by-step explanation:
Xavier total = 320 + 12h
Dayuans total = 266 + 30h
Where h = number of months
The inequality to determine the number of months xavier's account balance will be greater than dayuans account balance is
320 + 12h > 266 + 30h

Lois builds a cage for her hamster. The cage is a right rectangular prism. The height of the cage is 2 feet. The length and width are both x feet more than the height. Which expression represents the volume, in cubic feet, of the cage?
A. x^2 +6
B.2x^2+4x+4
C.x^2+4x+6
D.2x^2+8x+8
Answer:
[tex]V=2x^2+8x+8[/tex]
Step-by-step explanation:
The volume of a right rectangular prism is given by :
[tex]V=lbh[/tex]
Where,
l is length, bis breadth and h is height
ATQ,
Height of the cage is 2feet
The length and width are both x feet more than the height.
l = b = (x+2)
So,
[tex]V=(x+2)(x+2)2\\\\V=(x+2)^22\\\\V=(x^2+4+4x)2\\\\V=2x^2+8+8x[/tex]
