Jane had $d to buy three beanie babies.(in our problem they all cost the same). If she were to buy all three, she'd spend all her money. Instead, she bought just one. How much money dose Jane have left
Answer:
$4
Step-by-step explanation:
If she have $6 so 6-2=4
If buying 3 beanies babies of same cost costs $d (all money that Jane had), then buying only one such beany baby would save Jane $2d/3
How can we interpret the division?When 'a' is divided by 'b', then the result we get from the division is the part of 'a' that each one of 'b' items will get.
Thus, if 10 mangoes are there, and 2 people, then 10 ÷ 2 is the number of mangoes each person would get, which is 5.
Division, thus, can be interpreted as equally dividing the number that is being divided in total x parts, where x is the number of parts the given number is divided.
Thus, [tex]a \div b[/tex]= a divided in b equal parts.
Also, we can write: [tex]a \div b = a \times \dfrac{1}{b}[/tex]
(it is since a = a times 1 so [tex]a/b = 1 \times (a/b) = (1/b) \times a[/tex] )
Given that:
Total money Jane had = $d3 beanie babies are of same costTheir whole cost is $d (as buying them all makes Jane spend all her money).To find:
The amount she'd save if she buy only one such beanie baby.
Amount that she'd save = Total amount she could've spent - Total price of one beanie baby
As we know, total amount she could've spent = $d
Also, because of 3 beanie babies cosing equal, and total cost being $d,
the cost of each beanie baby is:
$d divided in 3 equal parts = d/3 dollars
Thus, we get:
Amount that she'd save = Total amount she could've spent - Total price of one beanie baby
Amount that she'd save = [tex]d - \dfrac{d}{3} \: \rm dollars[/tex]
We can write d = 3d/3 since dividing and multiplying a number by same non-zero number doesn't affect that number.
We do so, so that that both terms could get in fraction form with same denominator so that numerators could work directly.
[tex]d - \dfrac{d}{3} = \dfrac{3d}{3} - \dfrac{d}{3} = \dfrac{3d - d}{3} = \dfrac{2d}{3}[/tex]
Thus, if buying 3 beanies babies of same cost costs $d (all money that Jane had), then buying only one such beany baby would save Jane $2d/3

27
Step-by-step explanation:
Seems like your question(shown/written) is incomplete. Based on the given data.
15% of the total students participated in soccer
15% of 180 students participated in soccer

On the set of axes below, draw the graph of y=x^2-4x-1
9514 1404 393
Answer:
axis of symmetry: x = 2
see below for a graph
Step-by-step explanation:
You can complete the square to put the equation in vertex form.
y = (x^2 -4x +4) -1 -4
y = (x -2)^2 -5 . . . . . . vertex is (2, -5)
The equation of the axis of symmetry is the equation of the vertical line through the vertex:
x = 2 . . . . . axis of symmetry
__
Points on the graph are easily found by using integer values on either side of x=2. Points on one side of the axis of symmetry are mirrored on the other side of it.

Margaret and Kevin both have to write an expression that is equivalent to 6 to the power of -4. Part A Who is correct? Part B What is a possible error made by the incorrect student?
Margaret writes 6 x (1/6 to the power of 5)
Kevin writes 1/6 x (6 to the power of 4)
Please help
Answer:
Margret is correct, Kevin is wrong.
Step-by-step explanation:
6^-4 can be written as (1/6)^4
By taking (1/6)^5 times you have (1/6)(1/6)(1/6)(1/6)(1/6), multiplying by 6 would cancel one of those (1/6ths) out. Meaning you would be left with (1/6)^4 or 6^-4
Kevin is wrong because taking 6^4 would not be the same as 6^-4, 6^4= 1296, multiplying that by 1/6 would not give you the same value as 6^-4. His mistake was that he did not take the reciprocal of 6^-4 and incorrectly removed a negative.

-Lil G
Answer:
x=25
Step-by-step explanation:
Hey There!
Those angles are supplements meaning all of them added together will equal 180
so we set up an equation
180 = 3x+2x+80 and solve for x
step 1 combine like terms
3x+2x=5x
now we have
180=5x+80
step 2 subtract 80 from each side
180-80=100
80-80 cancels out
now we have
5x=100
step 3
divide each side by 5
5/5 cancels out
100/5=25
x=25
Therefore the value of x is 25
Hope this helps :)
Please help will give brainliest number 8.
Answer:
x = 1
Step-by-step explanation:
Were trying to solve for x so we would say 3 1/2 - 2 1/2 and we would be left with 1. So x=1, which you then substitute into the problem to make sure it's correct so 2 1/2 + 1 = 3 1/2.

Solve this equation v^2 - 2v = 3
Answer:
v = − 1 or v = 3
Step-by-step explanation:
Let's solve your equation step-by-step.
[tex]v^{2}[/tex] − 2v = 3
Step 1: Subtract 3 from both sides.
[tex]v^{2}[/tex] − 2v − 3 = 3 − 3
[tex]v^{2}[/tex] − 2v − 3 = 0
Step 2: Factor left side of equation.
( v + 1 ) ( v − 3 ) = 0
Step 3: Set factors equal to 0.
v + 1 = 0 or v − 3 = 0
v = −1 or v = 3

At a baseball game henry bought 5 hot dogs and three bags of chips for $14.82. Scoot bought 7 hotdogs and 6 nags of chip for $22.98. Find the cost of each hotdog and bag of chips
2.25
per hot dog
1.19
per bag o' chips
Explanation:
5x +3y = 14.82
7 x+6y = 22.89
− 10x−6y = −29.64
7 x+6y = 22.89
−3x = −6.75
x=2.25
5⋅2.25+3y = 14.82
3y = 14.82 − 11.25
y = 3.57 /3 = 1.19
The cost of each hot dog and bag of chips is $2.22 and $1.24
What is a system of equations?A set of simultaneous equations, also known as a system of equations or an equation system, is a finite set of equations for which common solutions are sought.
Given that, At a baseball game Henry bought 5 hot dogs and three bags of chips for $14.82. Scoot bought 7 hot dogs and 6 nags of chip for $22.98.
Let the unit prices of hot dogs and chips be h and c respectively,
Therefore, establishing the equations,
5h + 3c = 14.82...(i)
7h + 6c = 22.98....(ii)
Multiply eq(i) by 2 and subtract eq(ii) by eq(i)
(10h + 6c = 29.64) - (7h + 6c = 22.98)
3h = 6.66
h =2.22
Put h = 2.22 in eq (i)
5(2.22) + 3c = 14.82
11.1 + 3c = 14.82
3c = 3.72
c = 1.24
Hence, the cost of each hot dog and bag of chips is $2.22 and $1.24

The tyre of a car wheel has an outer diameter of 30 cm . How many times will the wheel rotate on a journey of 5 km
Answer:
5305.1647 times
Step-by-step explanation:
The Circumference of a circle : πd
d = diameter of circle = 30 cm
Circumference of wheel = π * 30cm = 94.247779 cm
1km to cm
1km = 100000cm
5 km = 500000 cm
Hence, number of times wheel rotate on a 5km journey :
500000 cm / 94.247779 cm
= 5305.1647 times
