Layla and Amelia are making bracelets. It takes Layla 45 minutes to make 9 bracelets on her own. Together, Layla and Amelia can make 9 bracelets in 20 minutes. How long will it take Amelia to make 9 bracelets?
Answer:
Step-by-step explanation:
It takes Layla 45 minutes to make 9 bracelets on her own.
45 divided by 9 equals 5. It takes Layla 5 minutes to make one bracelet.
Layla and Amelia can make 9 bracelets in 20 minutes.
20 divided by 9 equals 2 and 2/9.
5 - 2 2/9= 2 7/9
2 7/9 times 9 equals 25
Amelia can make 9 bracelets in 25 minutes
So it takes Layla 56 minutes to make 9 ( 45 divided by 9 = 5) so that means in 20 minutes Layla will make 4 bracelets.
this means it will piece together as Layla would make 4 while Amelia makes 5. So i think on Amelia's own it'll take her 40 minutes.
so sorry if i'm wrong :(

Draw a line graph by hand, labeling the vertical and horizontal axis consistent with your choice of variables. The line in the line graph has to represent, what, in your view, is the relationship between the two variables. Describe your graph verbally in your post (no need to upload the graph itself
Using a linear function, given by S(x) = 10 + 2x, we have that:
The independent variable is the number of weeks x.The dependent variable is the savings after x weeks, given by S(x).The graph means that the balance starts at $10 and increases by $2 each week.What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.The value of y depends on the value of x, hence x is the independent variable and y is the dependent variable.One example is a person with savings of $10, and the amount increases by $2 each week, hence the relation is:
S(x) = 10 + 2x.

The length of a rectangle is 12 feet less than 6 times its width. If the perimeter of the rectangle is
312 feet, find the length and width of the rectangle.
If the perimeter of rectangle is 312 feet,
The length and width of the rectangle are 132 feet and 24 feet
let the width of the given rectangle be x feet
then as per the information provided in the question , the length of rectangle is 6x-12 feet
the parameter of the rectangle is the two times the sum of its length and breath = 2(l+ b)
We are already provided with the parameter of the rectangle as 312 feet
So, let us put the value of length and breath along with the parameter in the formula
312= 2( (6x-12) + x
312= 2( 6x-12 + x)
312= 2(7x-12)
312= 14x - 24
312+24 =14x
336=14x
therefore x= 24
Hence, the length and width of the rectangle are 132 feet and 24 feet

the younger sister's age in September 2022. Then use the equations you created to solve for all of their ages.
The younger sister is 29.
The older sister is 49.
Mr Fishman's age is 47.
What are their ages?Let:
x = older sister's age x = younger sister's age c = Mr. Fishman's ageThe difference between the older sister and younger sister's age: y - x = 20 equation 1
Mr Fishman's is 11 years less than twice his young sister's age: 2x - 11 = c equation 2
The difference between Mr Fishman and his older sister's age : y - c = 2
y - 2 = c equation 3
Let equation 2 and 3 be equal : 2x - 11 = y - 2
2x - y = 11 - 2
2x - y = 9
-y + 2x = 9 equation 4
The two equations that would be used are:
y - x = 20 equation 1
-y + 2x = 9 equation 4
Add both equations together
x = 29
Substitute for x in equation 1
y - 29 = 20
y = 29 + 20
y = 49
y - c = 2
49 - c = 2
c = 49 - 2

Using proportions, it is found that:
a) They can paint 2.8 pictures in one hour.
b) The rate per hour is of 131.2 magazines.
c) The unit rate is of 0.86 problems per minute.
d) He can make 92.5 tacos in one hour.
e) He walks 3.75 miles in one hour.
The code is of 148.79.
What is a proportion?A proportion is a fraction of a total amount, and the measures can be related using a rule of three, which derives from proportional relationships.
Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures, involving operations such as division and multiplication, as they involve unit rates.
A unit rate is given by amount or fraction divided by time. Hence, for item a, it is given as follows:
4/5/(2/7) = 4/5 x 7/2 = 2.8.
They can paint 2.8 pictures in one hour.
For item b, we have that:
328/2.5 = 131.2.
The rate per hour is of 131.2 magazines.
For item c, we have that:
15/17.5 = 0.86.
The unit rate is of 0.86 problems per minute.
For item d, we have that:
185/2 = 92.5.
He can make 92.5 tacos in one hour.
For item e, we have that:
0.75/0.2 = 3.75.
He walks 3.75 miles in one hour.
For the code, the letters are given as follows:
E = 3.75, B = 131.2, D = 92.5, A = 2.8, C = 0.86.
Hence the code is given by:
E(B - D) + (A + C) = 3.75(131.2 - 92.5) + (2.8 + 0.86) = 3.75(38.7) + 3.66 = 145.13 + 3.66 = 148.79.

Find the equation of the line though the point (−4,−1) and perpendicular to the line y=25x+7. Write your answer in the form y=mx+b.
The equation of the line though the point (−4,−1) and perpendicular to the line y=25x+7 is y = -(1/25)*x - 21/25
How to find the equation of the line?
We want to find a line perpendicular to y = 25x + 7, then the slope of our line must be the inverse of the opposite of 25, this is:
a = -(1/25)
Then our line is something like:
y = -(1/25)*x + b
And we want this to pass through (-4, -1), then:
-1 =-(1/25)*-4 + b
-1 = 4/25 + b
-1 + 4/25 = b
-25/25 + 4/25 = b
-21/25 = b

How do I solve 9-2(p+1)=4(p-8)
Answer:
Step-by-step explanation:
First, distribute the -2 to the p and +1 in the parentheses.
9-2(p+1)=4(p-8)
9-2p-2=4(p-8)
Then on the other side do the same thing distributing the 4 to the p and -8.
9-2p-2=4(p-8)
9-2p-2=4p-32
Now isolate the variable p by adding 2p to each side
9-2p-2=4p-32
9-2=6p-32
From here you subtract 9 from 2 and then add 32 to both sides.
7=6p-32
39=6p
finally you divide both sides by 6 to get p.
39/6=p
