Sara says, "If you subtract 15 from my number and multiply the difference by -7, the result is -133. What is sara's number
Answer:
39
Step-by-step explanation:
-133/-7=19+15=39
check:39-15=19
19x(-7)=-133
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)

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

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.

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.

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°

Student B
Step-by-step explanation:
Proportional relationship means that it follows a certain pattern or is constant.
Student B was the only relationship to be constant as it goes by multiples of 6.
Ex. 6, 12, 18, 24, 30.
Answer:
Student B
Step-by-step explanation:
Student B's wages increase by 6 each time, but Students A, C, and D do not steadily increase. The steady increase of 6 for Student B is what makes their wages proportional.
The function f(x)f(x) is a quadratic function and the zeros of f(x)f(x) are 11 and 55. The y-intercept of f(x)f(x) is 2020. Write the equation of the quadratic polynomial in standard form.
Answer: [tex]4x^2 -24x+20[/tex]
Step-by-step explanation:
If p and q are zeroes of f(x), then f(x) = k (x-p)(x-q) , where k is a constant.
Given: The function f(x)f(x) is a quadratic function and the zeros of f(x)f(x) are 1 and 5.
f(x) = k (x-1)(x-5)
y-intercept = Value of function at x=0
So, y-intercept = k (0-1)(0-5)= 5k
Since, y-intercept of f(x) = 20
so, 5k = 20
⇒ k= 4
Quadratic polynomial [tex]= 4(x-1)(x-5)[/tex]
[tex]=4(x^2-6x+5)\\\\= 4x^2 -24x+20[/tex]
Hence, the equation of the quadratic polynomial in standard form =[tex]4x^2 -24x+20[/tex]

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.

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
