Answer:
8x +4y
Step-by-step explanation:
6x + 3y + 2x + y
1) add similar variables together.
2) 6x + 2x = 8x
3y + (1)y = 4y.
3) y by itself basically means 1y, since in front of every variable theres an invisible 1.
6x + 3y + 2x + y
Simplified: 4 · ( 2x + y)
Answer= 11y
El jueves se vendieron 13.520 entradas para ver un partido de hockey y el viernes 14.608. Si en el polideportivo caben 50.000 personas. ¿Cuántas entradas se pueden vender todavía?
Answer:
21,872 tickets
Step-by-step explanation:
The computation of the number of tickets to be still sold is given below:
= Total people accommodated - total number of tickets sold yet
= 50,000 people - (13,520 tickets + 14,608 tickets)
= 50,000 people - 28,128 tickets
= 21,872 tickets

The football team plays at a stadium with
dimensions of 50 feet X 60 feet of seating
for spectators. Find the total area of the
football stadium’s spectator area?
Answer:
1,100
Step-by-step explanation:
The total area of the football stadium's spectator area is 3000 square feet.
What is the area of the rectangle?The area of a rectangle is defined as the product of the length and width.
The area of a rectangle = L × W
Where W is the width of the rectangle and L is the length of the rectangle
The total area of the football stadium's spectator area is the product of the length and width of the seating area.
Since the length of the seating area is 50 feet and the width is 60 feet, the total area is:
total area of the football stadium = 50 feet × 60 feet
Apply the multiplication operation, and we get
total area of the football stadium = 3000 square feet
Therefore, the spectator space of the football stadium is 3000 square feet in total.

Both answer is 65
Step-by-step explanation:
5x -30 = 2x +27
5x -2x = 27 +30
3x = 57
x = 57/3 = 19
5x -30 = 5(19) -30 = 65
2x +27 = 2(19) +27 = 65
A square outdoor patio with side length x feet is surrounded by a brick walkway that is 4 feet wide. What is the area of the walkway
Answer:
Area of walkway = 16(x+4) [tex]ft^{2}[/tex]
Step-by-step explanation:
Length of the sides of the square outdoor = x feet
Area of the square outdoor = length x length
= x * x
= [tex]x^{2}[/tex] [tex]ft^{2}[/tex]
The square outdoor is surrounded by 4 feet of walkway. So that,
length of the walkway = (x + 2(4))
= (x + 8)
Area of walkway with outdoor = (x + 8)*(x + 8)
= ([tex]x^{2}[/tex] + 16x + 64) [tex]ft^{2}[/tex]
Area of walkway = Area of walkway with outdoor - Area of the square outdoor
= ( [tex]x^{2}[/tex] + 16x + 64) - [tex]x^{2}[/tex]
= 16x + 64
Area of walkway = 16(x+4) [tex]ft^{2}[/tex]

Sebuah persegi di bagi menjadi 3 persegi panjan yang jika di sejajarkan mempunyai keliling 140cm Berapa luas persegi sebelum di bagi
Answer:
1225 cm²
Step-by-step explanation:
Keliling persegi diberikan sebagai 4 × a
Dimana a = Panjang sisi
Keliling persegi di atas = 140
Karenanya:
4a = 140
a = 140/4
a = 35 cm
Panjang sisi bujur sangkar = 35cm
Luas persegi = (Panjang sisi) ²
Karenanya:
Luas persegi = (35cm) ²
= 1225 cm²
Luas persegi sebelum membagi adalah 1225 cm²
Solve the equation with the quadratic formula 4k^2-11k-18=0
Answer:
D
Step-by-step explanation:
Quadratic formula tells us that the roots are equal to:
[tex]\frac{-b\pm \:\sqrt{b^2-4ac}}{2a}[/tex]
The letters are just the coefficients, so a = 4, b = -11, and c = -18. Plugging these values into the formula we get:
[tex]\frac{-11\pm \sqrt{11^2-4\cdot \:4\left(-18\right)}}{2\cdot \:4}[/tex]
Which when simplified tells us that the roots are:
[tex]\frac{-11+\sqrt{409}}{8}[/tex] or [tex]\frac{-11-\sqrt{409}}{8}[/tex]
Remember the plus or minus sign is what gives us two answers.

Rita traveled 1 unit left and 3 units up. She ended at the grocery store. The ordered pair describes where she started. Need coordinate grid plz ME IN RUSH PLZ ANSWER
Answer:
(3,2)
Step-by-step explanation:
Missing Information:
The coordinate of the grocery store is: (2,5).
Required:
Determine the starting point
Assume the starting coordinate is (x, y)
When a point (x, y) is translated b units left, the image of the translation is: x -> x - b
In this case:
b = 1 (i.e. 1 unit left)
So, we have:
[tex](x-1,y)[/tex]
When a point (x, y) is translated h units up, the image of the translation is: y -> y + h
In this case:
h = 3 (i.e. 3 units up)
So, we have:
[tex](x-5,y+3)[/tex]
So, the expression that describes the grocery store is:
[tex](x-1,y+3) = (2,5)[/tex]
By comparison:
[tex]x-1 = 2[/tex]
[tex]y+3=5[/tex]
Solve for x
[tex]x = 2 + 1[/tex]
[tex]x = 3[/tex]
Solve for y
[tex]y = 5 - 3[/tex]
[tex]y = 2[/tex]
Hence, the starting point is: (3,2)

Which system of equations is represented by lines m and n?
a. 3x - y = 6
4x + 9y = 4
b. 3x - y = 2
4x + 9y = 36
C. x-3y = -18
9x + 4y = 9
d. x + y = 10
9x + 4y = 13
Answer:
B
Step-by-step explanation:
slope formula
[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
we have the two points
(2,4) (3,7)
[tex]\frac{7-4}{3-2}=3[/tex]
which means the slope for line m is 3x
our equation so far looks like this
y=3x+b
plug in a set of numbers to solve for b
let's use (2,4)
4=3(2)+b
4=6+b
b= -2
which means our equation is
y= 3x-2
which is equal to
2= 3x-y
the only answer is then B

A farm lets you pick 2 pounds of blueberries for 5 dollars.
1. the unit rate of dollars to pounds is ___ dollars per 1 pound
2. the unit rate of pounds to dollars is ___ pounds per 1 dollar
Answer:
1. $2.5
2. 2/5lb
Step-by-step explanation:
1. The blank is asking what the cost of one pound of blueberries costs and you know that two pounds costs $5, so half of 5 is 2.5. So the first blank is $2.5.
2. You know that $2.5 will get you one pound, so divide by 5 and now you know that $0.50 will get you 1/5 pound of blueberries. multiply by two and now you know that $1.00 get you 2/5 pound of berries. So the second blank is 2/5 lb.
Answer:
1. 2.50 dollars
2. 0.2 pounds
Step-by-step explanation:
Sorry if I explain things you might not understand.
1. To find how much one pound is, you solve the equation 2 / 5 = 1 / P. You solve for P which will be 2.5 or 5/2
2/5 = 1/P
2/5 x P x 5/2 = 1 / P x P x 5/2
P = 5/2
2. To find the amount of pounds per dollar, you solve the equation 5/2 = 1/D. You solve for D which will be 2/5 or 0.2 dollars.
5/2 x D x 2/5 = 1/D x D x 2/5
D = 2/5

On the number line, which point is the closest pi .
A.
B.
C.
D.
The closest point to the number line is C.
Hence Option C is correct.
In the given number line
There are 10 equidistant points between 3.1 and 3.2
So, the set of points shown on the line is,
{3.1, 3.11, 3.12, 3.13, 3.14, 3.15, 3.16, 3.17, 3.18, 3.19, 3.2}
Therefore,
Point c represents point 3.14 approximately.
Since we know that π is an irrational number,
So it is non-terminating and non-repeating but for approximation,
π = 22/7
π ≈ 3.142
Hence,
The point C is very close to the π.
