Alyssa bought 2 packs of football cards for $4.62 each, and a deck of Digimon cards
for $11.47 with two $20 bille, Alyssa found $7.72 in her pocket. How much change
did Alyasa get?
Hello :D
2 x $4.52 = $9.04
$9.04 + $11.47 = $20.51
2 x $20 = $40.00
$40.00 - $20.51 = $19.49
With change:
$40.00 + $7.72 = $47.72
$47.72 - $20.51 = $27.21

The sum of 5 consecutive integers is 110 what is the 4th number of this sequence
Step-by-step explanation:
Let 5 consecutive no. be
n, n+1,n+2,n+3,n+4
n+n+1+n+2+n+3+n+4=110
5n+10=110
5n=110-10
5n=100
n=100/5
n=20
4th term is n+3=20+3=23

Answer:
x = 7
Step-by-step explanation:
RT= RS+ST
70 = (7x +2 ) + (2x+5)
70 = 9x + 7
9x= 70 - 7
9x = 63
x= 63/ 9
x = 7
I hope I helped you^_^
Answer:
[tex]given \: that \: total \: length \: rt = 70 \\ \: then \: rs + st = rt \\ 7x + 2 + 2x + 5 = 70 \\ 9x + 7 = 70 \\ 9x = 63 \\ x = \frac{63}{9} \\ x = 7 \\ thank \: you[/tex]

If 8(x - 2y) = 16x, then what is x in terms of y?
Answer: y = -1/2x
8(x - 2y) = 16x
8x -16y = 16x
-16y = 16x-8x
-16y = 8x
-16y/-16= 8x/-16
y = -1/2x

Volumen de un cilindro: es igual al área de la tapa por la altura del mismo
A = πD² * h / 4
Lata grande y lata pequeña
Para la lata grande, el diámetro y la altura han aumentado un 20%.
Lata pequeña:
d = 4 cm
h = 3 cm
A 1 = π * (4) ² * 3/4
A1 = 37,70 cm²
Lata grande:
d = 4 * 1,2 = 4,8 cm
h = 3 * 1,2 = 3,6 cm
A2 = π (4,8) ²3,6 / 4
A2 = 65,14 cm²

6. Find the circumference and area of a circle with a diameter of 8 meters. Leave your answers in terms of . Write "pi" instead of the symbol
Answer: Area = 16*pi m^2
Circumference = 8*pi
Step-by-step explanation: The circumference and area of a circle are given by:
Area = pi*r^2
Circumference = 2 pi*r
Radius = Diameter/2, or 4 meters (m)
Area = 16*pi m^2 (50.27 m^2)
Circumference = 8*pi (25.13 m)
Find the distance between the points (-6, – 7) and (5. – 7).
Answer:
11
Step-by-step explanation:
d=√(5-(-6))²+(-7-(-7))²
d=√(11²+0²)
d=11
Answer:
[tex]\boxed {\boxed {\sf d= 11}}[/tex]
Step-by-step explanation:
We are asked to find the distance between 2 points. We will use the distance formula.
[tex]d= \sqrt{ (x_2-x_1)^2+(y_2-y_1)^2[/tex]
In this formula, (x₁ , y₁) and (x₂ , y₂) are the points. We are given the points (-6, -7) and (5, -7). If we match the value and the corresponding variable, we see that:
x₁ = -6 y₁ = -7 x₂ = 5 y₂ = -7Substitute these values into the formula.
[tex]d= \sqrt{(5- -6)^2 + (-7--7)^2[/tex]
Solve inside the parentheses. Remember that two back-to-back negative signs become a plus sign.
(5 - - 6) = (5 +6) = 11( -7 - - 7) = (-7 +7) = 0[tex]d= \sqrt{ (11)^2+(0)^2[/tex]
Solve the exponents.
(11)² = 11 * 11 = 121 (0)² = 0*0= 0[tex]d= \sqrt{(121)+(0)[/tex]
Add.
[tex]d= \sqrt{121}[/tex]
[tex]d=11[/tex]
The distance between (-6, -7) and (5, -7) is 11.

Answer:
Step-by-step explanation:
Perimeter = 2W + 2L
160 = 2W + 2L
width = 16 feet less than length
W = L - 16 ------------(I)
Finding the dimensions of the court:
2W + 2L = 160
2*(L-16) + 2L = 160 {from (I) }
2*L - 2*16 + 2L = 160 {Distributive property}
2L - 32 + 2L = 160
2L + 2L - 32 = 160 {Combine like terms}
4L - 32 = 160 {Add 32 to both sides}
4L = 160 +32
4L = 192 {Divide both sides by 4}
L = 192/4
L = 48
W = 48 - 16
W = 32

Answer: D
Step-by-step explanation:
Johhny Badoingas collects $0.12 from a 1000 people, how much does he have altogether. Now he has to share that total product with 100 people, how much does each person get?
Find total collected by multiplying the amount per person by number of people:
1000 x 0.12 = $120.00
Total collected = $120.00
Divide total collected by number of people:
120.00 / 109 = $1.20
Each person gets $1.20

helpppppppppppppppppppppppppppppppppppppppp
Step-by-step explanation:
let : the pair of jeans = X
a. the equation is :
4(X-3) + 8 = 92
b. 4(X-3) = 92-8
4X -12 = 84
4X = 84+12
4X = 96
X = 96/4
X = 24
so, the price of each pair of jeans = $24

For the solution x = 2.6, the left side of equation
(2x - 6) => would be 2(2.6)-6 = 5.2-6 = -8 ( the negative value),
but on the right side of the equation 4x+8 => 4(2.6) +8 = 18.4 ( the positive value)
this difference indicates that x=2.6 is not the right solution.
Answer:
a) Let x be the cost of one pair of jeans
[tex]4(x-3)+8=92[/tex]
b) $24
Step-by-step explanation:
Given information:
Cost of t-shirt = $8Coupon used for $3 off each pair of jeansTotal spend = $92 (before tax)Define the variable:
Let x = the cost of one pair of jeans
Create an equation using the defined variable and the given information:
Apply the coupon ⇒ cost of one pair of jeans = (x - 3)4 pairs of jeans ⇒ 4(x - 3)Plus the cost of the t-shirt ⇒ + 8Equals the total cost of ⇒ = 92:[tex]4(x-3)+8=92[/tex]
To find the price of each pair of jeans, solve the equation for x:
[tex]\implies 4(x-3)+8=92[/tex]
[tex]\implies 4(x-3)+8-8=92-8[/tex]
[tex]\implies 4(x-3)=84[/tex]
[tex]\implies \dfrac{4(x-3)}{4}=\dfrac{84}{4}[/tex]
[tex]\implies x-3=21[/tex]
[tex]\implies x-3+3=21+3[/tex]
[tex]\implies x=24[/tex]
Therefore, the price of each pair of jeans was $24.
----------------------------------------------------
Solving 3(2x - 6) = 4x + 8 mentally:
Expand the brackets:
⇒ 16x - 18 = 4x + 8
Subtract 4x from both sides:
⇒ 12x - 18 = 8
Add 18 to both sides:
⇒ 12x = 26
Two times 12 is 24. As 26 is very close to 24, then x ≈ 2.
(The actual value of x is 2.2 to 2 decimal places).
Assessing the student's solution:
As x = 2.6 rounds to x ≈ 3 then the student's solution is incorrect because:
⇒ 3(2(3) - 6) = 4(3) + 8
⇒ 3(6 - 6) = 12 + 8
⇒ 3(0) = 20
⇒ 0 = 20
Okay guys please help and explain it accurately and solve please so I can understand it. This is for 100 points!
-6a + 10 = -27
-6a + 10 = -27
First step: subtract 10 from both sides:
-6a = -37
Now divide both sides by -6:
A = -37/-6
Simplify:
A = 37/6
Answer:
a = 37/6
Step-by-step explanation:
-6a +10 = -27
Subtract 10 from each side using the subtraction property of equality
-6a+10-10 = -27-10
-6a = -37
Divide each side by -6 using the division property of equality
-6a/-6 = -37/-6
a = 37/6

30. f(x) = |x|; reflection in the y-axis followed by a
translation 3 units right
Answer:
[tex]g(x) = |x-3|[/tex]
Step-by-step explanation:
We are given the parent function:
[tex]f(x) = |x|[/tex]
And we want to find the equation after a reflection in the y-axis followed by a translation of three units right.
To reflect a function over the y-axis, we multiply the input by a negative. That is:
[tex]\displaystyle f(x) \rightarrow f(-x)[/tex]
In other words, a reflection over the y-axis will be given by:
[tex]f(-x) = |-x|[/tex]
To shift horzontally, we add if we are moving leftwards or subtract if we are moving rightwards. That is:
[tex]f(x) \rightarrow f(x-k)[/tex]
Where k is the horizontal translation.
Since we are translating three units rightwards, k = 3. Hence:
[tex]\displaystyle f(-(x-3)) = |-(x-3)|[/tex]
Recall that |ab| = |a||b|. Hence:
[tex]\displaystyle f(-(x-3)) = |-(x-3)| = |-1||(x-3)| = |x-3|[/tex]
Hence, f reflected over the y-axis followed by a translation of three units right is given by:
[tex]g(x) = |x-3|[/tex]

Show your work and solve for x and y.
3x + y = 8
2x + 4y = 12
Answer:
x=2, y=2
Step-by-step explanation:
3x + y = 8
2x + 4y = 12
Multiply the first equation by -4
-12x -4y = -32
Then add to the second equation
-12x -4y = -32
2x + 4y = 12
------------------------
-10x + 0y = -20
-10x = -20
Divide by -10
-10x/-10 = -20/-10
x =2
Now find y
3x+y = 8
3(2)+y = 8
6+y = 8
y = 8-6
y =2
Answer:
[tex]\huge\boxed{\sf Solution Set = \{(2,2)\}}[/tex]
Step-by-step explanation:
3x + y = 8 ----------------------(1)
2x + 4y = 12 -------------------(2)
Multiply Eq. (1) by 4
4(3x+y) = 8*4
12x + 4y = 32 -----------------(3)
Subtract Eq. (3) from (2)
2x + 4y - (12x + 4y) = 12 - 32
2x + 4y - 12x - 4y = -20
2x - 12x = -20
-10x = -20
Divide both sides by -10
x = 2
Put x = 2 in Eq. (1)
3(2) + y = 8
6 + y = 8
Subtract 6 to both sides
y = 8 - 6
y = 2
Solution Set = {(x,y)} = {(2,2)}
