Emily and Chelsea each improved their yards by planting hostas and shrubs. They bought their supplies from the same store. Emily spent $132 on 6 hostas and 12 shrubs. Chelsea spent $213 on 14 hostas and 9 shrubs. Find the cost of one hosta and the cost of one shrub.
Answer:
One hosta = $ 12 , One shrub = $ 5
Step-by-step explanation:
Let;
x = hostas
y = shrubs
Emily spent $132 on 6 hostas and 12 shrubs.
6x + 12y = 132 ........................................ (i)
Chelsea spent $213 on 14 hostas and 9 shrubs
14x + 9y = 213 ........................................ (ii)
From (i)
12y = 132 - 6x
y = 11 - 0.5x ........................................ (iii)
substitute (iii) into (ii)
14x + 9 (11 - 0.5x) = 213
14x + 99 - 4.5x = 213
9.5x = 114
x = $ 12
Substitute value of x in (iii)
y = 11 - 0.5(12)
y = 11 - 6 = $ 5
Write the equation of the line that passes through the points (5,-10) and (12,-17) in slope intercept form
Answer:
m = -1Step-by-step explanation:
[tex]\bold{slope\, (m)=\dfrac{change\ in\ Y}{change\ in\ X}=\dfrac{y_2-y_1}{x_2-x_1}}[/tex]
(5, -10) ⇒ x₁ = 5, y₁ = -10
(12, -17) ⇒ x₂ = 12, y₂ = -17
So the slope:
[tex]\bold{m=\dfrac{-17-(-10)}{12-5}=\dfrac{-7}7=-1}[/tex]
Pls help and show workings
Step-by-step explanation:
AB = 72 so, then FB would be half of that
so 72 divided by 2 would be 36
5x+1=36 then do substitution
-1 from both sides (from +1 you gotta do the inverse)
5x = 35
divide 5 from both sides because in between 5 and x is a times so the inverse of that is divide
x = 7
How many different 4-digit PIN codes are there that only include the digits 3, 4, 6, 7, 9 and 2
if each of those digits is only allowed to be used once?
Answer:
840
Step-by-step explanation:
I got the answer from Hegarty
There are different 4-digit PIN codes are there that only include the digits 3, 4, 6, 7, 9 and 2.
What is Multiplication?To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
Numbers to make 4 - digit PIN codes are,
⇒ 3, 4, 6, 7, 9 and 2.
Now,
Since, There are 6 number to choose to make 4 - digit PIN codes.
Hence, Number of different choices to make 4 - digit PIN codes is,
⇒ [tex]^6P_{4} }[/tex]
⇒ 6! / (6-4)!
⇒ 6! / 2!
⇒ 6 × 5 × 4 × 3 × 2! / 2
⇒ 360
Thus, There are 360 choices to make 4 - digit PIN codes.

Alicia is programming computerized robotic arms to cut burlap for the 4th of July placemats.
The placemats are to be rectangular in shape with an area represented by
45x2 - 71% - 150. The width of each placemat is represented by 5x + 6. The expression to
represent the length of each placemat can be determined by the formula,
length = area = width. Which expression can Alicia use in the programming to represent the
length of each placemat?
А
9x - 25
B
9x + 25
C 45x2 - 66x - 144
D 9x2 - 14.2x - 30
Answer:
A
Step-by-step explanation:
The expression for the width of rectangular placemats is (9x - 25) units.
Given that, the area of rectangular placemats=45x²-70x-150.
What is the area of a rectangle?The area of a rectangle (A) is the product of its length 'a' and width or breadth 'b'. So, the area of the rectangle = (a × b) square units.
Now, 45x²-70x-150=(5x + 6)×b
⇒b=45x²-75x-150/(5x + 6)
⇒b=(5x + 6)(9x - 25)/(5x + 6)
⇒b=(9x - 25)
Therefore, the expression for the width of rectangular placemats is (9x - 25) units.

Pleaseeeee helpppppp
Answer:
Okay so I’m gonna do a few and list a few examples
In slope intercept form its
y=mx+b
Y= Random Y coordinate (Not that important for now while writing)
m= Slope
X= random x coordinate (not that important for now while writing)
b= Y intercept
SO basically plug it in like that so for the first one
the slope is 1/3 and y-intercept is -1
so
y=1/3x-1
And thats how you do it
leave the y and x
Graphing
So for graphing or fining the equation, first identify the y-intercept
The y-intercept is on the y axis (obviously), and its the number where the line first hits, so for the first one, the y intercept is 3 becuase thats where the first line meets on the Y axis. When identified start doing rise over run, lik just go up and right, if there is no space, dot he opposite, go down and go left or right (depends if the line is rising or falling, you can tell if rising (positive) if the line goes from down to up form left to right , if falling (negative) vice versa, up to down from left to right). And just write the equation after identifying the slope And y-intercept, the x and y don’t matter.
4) y= -1/3x+3 (watch your signs, if falling the slope is automatically negative)
5) y=1/2x+1
6) y=4x-5 (negative y-intercept due to the part where the y meets up with the line, its in the negative side)
(remember to write these equations on the top side of the line

Suppose M is the midpoint of FG. Find the missing measure.
MG = 13x + 1, FG = 15
Answer:
14 - 13x
Step-by-step explanation:
take 13x + 1 away from 15
15 - (13x + 1) = 15 - 13x - 1 = 14 - 13x
The value of x is 1/2 and the measure of MG is 7.5 cm.
Given that, M is the midpoint of FG.
We need to find the measure of MG and FM.
What is the midpoint of a line segment?In geometry, the midpoint is the middle point of a line segment. It is equidistant from both endpoints, and it is the centroid both of the segment and of the endpoints. It bisects the segment.
Now, FG=MG+FM
⇒FG=MG+MG (MG=FM)
⇒FG=2MG
⇒15=2(13x+1)
⇒15=26x+2
⇒x=1/2
Now, MG=FM=13(1/2)+1=7.5 cm
Therefore, the value of x is 1/2 and the measure of MG is 7.5 cm.

Step-by-step explanation:
The diagram shows you that the boxes have a length (L) to width (W) ratio such that ...
3L = l = 4W
L/W = 4/3
Suppose we call the width of the box 3 units, then its length is 4 units, and we have the crate dimensions ...
l = 4(3) = 3(4) = 12
w = 3+3+4 = 10
Then the ratio l : w is 12 : 10 = 6 : 5.

since a triangle has 180 degrees, the angles all have to add up to 180
So 180 = a + b + c
we already know a, its 95
So 180 = 95 + b + c
now we know the equation for b, so we'll just put it there instead of the b, and since the angles are the same, we should put it instead of c too
180 = 95 + (4x-15) + (4x-15)
now subtract 95 from both sides
85 = (4x-15) + (4x-15)
add the xs and numbers together
85 = 8x - 30
now add the 30 to both sides
115 = 8x
divide by 8
your x is 14 3/8 or 14.375 or 115/8
that's not your angle, that's your x

Prove that: (12^13–12^12+12^11)(11^9–11^8+11^7) is divisible by 3, 7, 19, and 37. The answer should be like: x^b*3*7*19*37. Also this is my first time asking a question on brainly :)
Answer:
Step-by-step explanation:
Given (12^13–12^12+12^11)(11^9–11^8+11^7),
(12^13–12^12+12^11)(11^9–11^8+11^7) =
[(12^12)12 – 12^12 + 12^11][(11^8)11 – 11^8 + 11^7)
[(12^12)(12 – 1) + 12^11][(11^8)(11 – 1) + 11^7] =
(12^12(11) + 12^11)(11^8(10) + 11^7) =
(12^11(12x11) + 12^11)(11^7(11x10) + 11^7) =
[(12^11)(12x11 + 1)][(11^7)(11x10 + 1)] =
[(12^11)x(11^7)](12x11 + 1)(11x10 + 1) =
[(12^11)x(11^7)](133 x 111) =
[(12^11)x(11^7)](133 x 111) =
[(12^11)x(11^7)](14763) =
[(12^11)x(11^7)](3x7x19x37)
From here, it is clear that the given number is divisible by 3, 7, 19 and 37.
