If both boxes of cookies together cost $4: -11.65
Please help me answer this question thank you.
Answer:
122°
Step-by-step explanation:
10a + 2° + 5a - 2° = 180° [ being linear pair ]
15a = 180°
a = 180° / 15
a =12°
Now
<XYQ = 10a + 2° = 10 * 12° + 2° = 120° + 2° = 122°
Hope it will help :)
Estimate the unit rate to the nearest hundredth $2.35 12 Grade AA eggs.
Answer:
2.4
Step-by-step explanation:
x+y=180
x=10y+48
(With Steps Plz)
Answer:
(168,12)
Step-by-step explanation:
Substitute x = 10y+48 in the first equation.
[tex]10y + 48 + y = 180 \\ 11y = 180 - 48 \\ 11y = 132 \\ y = \frac{132}{11} \\ y = 12[/tex]
We have got the y-value. Our next goal is to find the x-value by substituting y-value in any given equations.
For me, I will be substituting y = 12 in the first equation.
[tex]x + 12 = 180 \\ x = 180 - 12 \\ x = 168[/tex]
Answer Check
Substitute both x-value and y-value in both equations.
[tex]168 + 12 = 180 \\ 180 = 180[/tex]
Our first equation is true for both values.
[tex]168 = 10(12) + 48 \\ 168 = 120 + 48 \\ 168 = 168[/tex]
Our second equation is true for both values.
Thus, the answer is (168, 12)

Which statements are true about the ordered pair (−1, 5) and the system of equations?
Answer:
Option D is correct answer.
Step-by-step explanation:
We are given the system of equations:
[tex]x+y=4\\x-y=-6[/tex]
Solving the system of equations to find values of x and y
Let:
[tex]x+y=4--eq(1)\\x-y=-6--eq(2)[/tex]
Adding both equations to find value of x
[tex]x+y=4\\x-y=-6\\------\\2x=-2\\x=\frac{-2}{2}\\x=-1[/tex]
So, we get value of x: x=-1
Now, putting value of x: x=-1 into equation 1 to find value of y
[tex]x+y=4\\Putx=-1\\-1+y=4\\y=4+1\\y=5[/tex]
So, we get value of y: y=5
The ordered pair will be: (-1,5)
So, Option D: The ordered pair(-1,5) is a a solution to the system of equations because it makes both equations true is correct choice.
Checking:
Put x=-1 and y=5 in equation 1
[tex]x+y=4\\-1+5=4\\4=4\:True[/tex]
Put x=-1 and y=5 in equation 2
[tex]x-y=-6-1-5=-6\\-6=-6\:\:\:True[/tex]
So, both equations are true.
Therefore, Option D is correct answer.

Brainly annie has 2 bags of apples and 5 single apples eva has 1 bag of apples and 11 single apples they have the same amount of apples how many apples so they have in total
Answer:
34 apples
Step-by-step explanation:
To answer: try setting up each of the equations for Annie and Eva.
Annie: 2(bag) + 5
Eva: 1(bag) + 11
Those two equations equal each other. So set that up:
2(bag) + 5 = 1(bag) + 11
Now solve for the size of the bag.
2(bag) - 1(bag) = 11 - 5
1(bag) = 6 apples
Now substitute 6 back into either equation to determine number of apples.
Annie: 2(6) + 5 = 12+5=17
They each have 17, so there are 34 apples in total.

Sinister Stan stole 3 3/4 oz of slime from Messy Molly, but his evil plans require 6 3/8 oz of slime. He stole another 2 3/5 oz of slime from Rude Ralph. How much more slime does Sinister Stan need for his evil plan?
Answer: 1/40
Step-by-step explanation:
Since we are told that Sinister Stan stole 3 3/4 oz of slime from Messy Molly and stole another 2 3/5 oz of slime from Rude Ralph. The total oz of slime stole would be:
= 3 3/4 + 2 3/5
= 3 15/20 + 2 12/20
= 5 27/20
= 6 7/20
We are told that his evil plans require 6 3/8 oz of slime, the amount needed for Sinister Stan for his evil plan would be:
= 6 3/8 - 6 7/20
= 6 30/80 - 6 28/80
= 2/80
= 1/40
find the equation of a line which passes through (2 4) with a slope of ½
Answer:
The equation of the straight line is x - 2y +6 =0
Step-by-step explanation:
Explanation:-
Given a point ( 2, 4) and slope m = [tex]\frac{1}{2}[/tex]
The equation of the straight line passing through the point and having slope 'm'
y - y₁ = m ( x - x₁)
y - 4 = [tex]\frac{1}{2}[/tex] ( x - 2)
2( y -4) = ( x-2)
2 y - 8 = x -2
x - 2 y - 2 + 8 =0
x - 2y + 6 =0
The equation of the straight line is x - 2y +6 =0
The answer is:
y = 1/2x + 5
Work/explanation:
Since I have a point and the slope, I will write the equation in point slope form.
Point slope is
[tex]\sf{y-y_1=m(x-x_1)}[/tex]
where m = slope and (x₁, y₁) is a point on the line
Plug in the data
[tex]\sf{y-4=\dfrac{1}{2}(x-2)}[/tex]
Now let's simplify to slope intercept
[tex]\large\begin{gathered}\sf{y-4=\dfrac{1}{2}x+1}\\\sf{y=\dfrac{1}{2}x+1+4}\\\sf{y=\dfrac{1}{2}x+5}\end{gathered}[/tex]
Hence, the equation is y = 1/2x + 5.four less that the quotient of six and two

A truck driver has a route that takes him 125 miles each way each day that he works. If he makes 15 roundtrips on this route per month, how many miles does he drive the truck per month?
Answer: 3,750 miles
Step-by-step explanation:
Route takes him 125 miles each way so in a day he travels:
= 125 + 125
= 250 miles
He made 15 roundtrips so total miles is:
= 15 * 250
= 3,750 miles

Amelia's Reliable Fencing Co. prices fences based on the amount of fencing installed plus a fixed amount of $200. The
company charges S4 per foot of standard fencing. Which of the following scenarios is correct?
It costs $1040 to enclose a 90' by 40' rectangular area.
It costs $560 to enclose a 50' by 40' rectangular area.
ОООО
It costs $2600 to enclose a 10' by 60' rectangular area.
It costs $1480 to enclose an 80' by 80' rectangular area.
Answer:
It costs $560 to enclose a 50' by 40' rectangular area.
Step-by-step explanation:
50 + 40 = 90
90 x 4 = 360 because of the $4 per foot
360 + 200 = 560, you add 200 because of the flat rate charge.
Find the value of X in order to prove that the two triangles are congruent by the SSS Congruence Postulate
Answer:
x=2
Step-by-step explanation:
17x-8=11x+4
Add 8 to both sides:
17x=11x+12
Subtract 11 x from both sides:
6x=12
Divide both sides by 6:
x=2
Value of [tex]\boldsymbol{x}[/tex] is [tex]\boldsymbol{2}[/tex] such that the two triangles are congruent as per the Side-Side-Side Congruence Postulate.
Side-Side-Side PostulateAccording to Side-Side-Side postulate, if the three sides of one the two triangles are congruent to each other then the two triangles are congruent.
Congruent triangles have the same shape as well as the same size.
[tex]\boldsymbol{\bigtriangleup MPQ\cong \bigtriangleup NPQ}[/tex]
This implies [tex]PM,PN[/tex] are same in length.
[tex]17x-8=11x+4[/tex]
[tex]6x=12[/tex]
[tex]x=2[/tex]
So, value of [tex]\boldsymbol{x}[/tex] is [tex]\boldsymbol{2}[/tex].

Jake rewrites the expression 81x4 – 1 as a difference of squares so he can factor it. Which answer choice shows how Jake could rewrite the expression?
Answer: (9x^2)^2 -1^2
Step-by-step explanation:
Jake rewrite the expression as,
⇒ (3x - 1) (3x + 1) (9x² + 1)
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The expression is,
⇒ 81x⁴ - 1
And, Jake rewrites the expression as a difference of squares so he can factor it.
Now, We can rewrite the expression as;
⇒ 81x⁴ - 1
⇒ (9x²)² - 1²
⇒ (9x² - 1) (9x² + 1)
⇒ ((3x)² - 1²) (9x² + 1)
⇒ (3x - 1) (3x + 1) (9x² + 1)

A regular octagonal pyramid. Each side of the base is 6 cm long. it has a height of 10cm. Find the surface area of the pyramid
9514 1404 393
Answer:
470.16 cm²
Step-by-step explanation:
The apothem of the base is used for two purposes: to find the area of the base, and to find the slant height of each face.
The apothem of the base for side length s is ...
s/2 = a·tan(π/8)
a = s/(2·tan(π/8)) ≈ 7.24 cm
The slant height of a triangular face is found using the Pythagorean theorem. The apothem of the base and the height are legs of the right triangle whose hypotenuse is the slant height. For slant height x, we have ...
x² = 10² + a² = 100 +52.46
x ≈ √152.46 ≈ 12.35
__
The area of the 8 triangular faces will be ...
A = 1/2Px . . . . where P is the perimeter of the pyramid
The area of the base will be ...
A = 1/2Pa
So, the total surface area is ...
A = 1/2P(a + x) = (1/2)(8)(6 cm)(7.24 +12.35 cm) ≈ 470.16 cm²
The answer is 470.16 cm²
