given l m n find the value of x.
(9x+18) = (2x+19)
Answer:
Step-by-step explanation:
Not sure what "given l m n " means...
If you want the value of x in (9x+18) = (2x+19)
then
(9x + 18) = (2x + 19)
9x + 18 - 18 = 2x + 19 - 18
9x = 2x + 1
9x - 2x = 2x - 2x + 1
7x = 1
7x/7 = 1/7
x = 1/7

William Shakespeare wrote 37 plays, including tragedies, comedies , and histories. He wrote the same number of tragedies and histories, He wrote the same number of tragedies and histories , but the number of comedies he wrote is 3 less than twice the number of tragedies. Write the system of equation to find how many of each type of play did Shakespeare write.
Answer:
10 tragic and histories, and 1y comedies
Step-by-step explanation:
let X = the number of tragedies
let X = the number of histories
2x - 3 = the number of comedies
x + x + 2x - 3 = 37
4x = 40
x = 10
2x - 3 = 2(10) - 3 = 17 comedies.

The cost of bananas, y, is directly
proportional to x, the pounds of bananas
purchased. If 2.5 lbs of bananas costs
$1.50, find the total cost of a lbs of
bananas.
The equation is y = 0.60x. Then the total cost of 9 lbs of bananas will be 5.4 lbs.
What are ratio and proportion?A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.
The cost of bananas, y, is directly proportional to x, the pounds of bananas purchased. Then the relationship is given as,
y ∝ x
y = kx
Then the relationship between 'x' and 'y' will be linear. If 2.5 lbs of bananas cost $1.50. Then we have
1.50 = k (2.5)
k = 0.60
Then the equation is given as,
y = 0.60 x
Then the total cost of 9 lbs of bananas will be given as,
y = 0.60 (9)
y = 5.4 lbs
The equation is y = 0.60x. Then the total cost of 9 lbs of bananas will be 5.4 lbs.

Joel has just moved to a new town and wants to share plates of baked goods with his
neighbors. He has 20 cookies and 5 brownies to share and wants to split them equally
among the plates with no food left over. What is the greatest number of plates he can make to share
Answer:
Marta can arrange a maximum of 3 plates.
Solution:
Given, Marta has just moved to a new town and wants to share plates of baked goods with her neighbors.
She has 18 cookies and 15 brownies to share, and wants to split them equally among the plates with no food left over.
We have to find what is the greatest number of plates she can make to share?
Now, let the number of brownies per each plate be n.
Then, number of plates used =
Here, n is number of brownies per plate and is number of cookies per plate.
So, both n and should be whole numbers. Then, for to be whole number 6n must be an multiple of 5.
And to be particular, n should be a multiple of 5 as 6 is not multiple of 5.
So, possible n values are, 5, 10, 15. We need not take above 15 as number of brownies available are 15
In order to arrange in more plates we have to take less count in single plate. Then, n = 5.
Now, number of plates
Hence, Marta can arrange a maximum of 3 plates.

Are these functions inverses of each other?Be sure to explain how you know they are inverse or why they are not. Show all work necessary.
Answer:
Yes. f(x) and g(x) are inverses of one another
Step-by-step explanation:
[tex]f(x) = - \frac{1}{2} x - 2 \\ y = - \frac{1}{2} x - 2 \\ x = - \frac{1}{2} y - 2 \\ x + 2 = - \frac{1}{2} y \\ - 2(x + 2) = - \frac{1}{2} y \times - 2 \\ - 2x - 4 = y \\ {f }^{ - 1} (x) = - 2x - 4[/tex]
In step 1 we just copied the original function.
In step 2 we substituted y for f(x).
in step 3 we switched the variables.
in step 4 we added 2 to both sides.
in step 5 we multiply both sides by -2
In step 6 we solved for y.
In step 7 is just a fancy way of saying the inverse function f(x) = -2x - 4

You and three friends go to the local fair. You each buy a $3 food ticket and a stamp for unlimited rides. If the total cost for the four of you is $32, how much does the stamp for unlimited rides cost?
Answer:
5$ for a stamp
Step-by-step explanation: First calculate the TOTAL amount of money spent on the food tickets. 4 friends, 3$ each for a ticket = 12$. Total cost is 32$ so do 32$-12$ to find how much else you paid after the 12$ on food ticket which is 20$. Divide the reamaining money (20$) by 4 because of the four friends. Than there is the price for the unlimited ride stamp 5$. Think of it like this. x+12=32. x=20, x/4=20/4 x=5$. Let me know if im wrong

can anyone help?????? Can y’all write it detailed or like step by step explaining cause i have to write it down ..
Answer:
x = 5
Step-by-step explanation:
Step 1: Distributive property
Using this property means when you have something like the equation on the right side ( 4 ( x + 3 ) ) you multiply both the values in the parentheses by the number outside:
4 ( x + 3 )
( 4 x X ) + ( 4 x 3 )
4x + 12
8x + 2 = 2x + 4x + 12
Step 2: combine like terms
Combining like terms is when you find like terms with the same variables and such and add them together:
8x + 2 = 12 + ( 2x + 4x )
8x + 2 = 12 + 6x
Step 3:Using inverse operations
This means that you need to get a variable one one side and a constant on the other:
8x + 2 ( -2 ) = 12 ( -2 ) + 6x
8x = 10 + 6x
8x ( -6x ) = 10 + 6x ( -6x )
2x = 10
Step 4: solve for the variable
The last thing you need to do is divide both sides by the constant with the variable ( 2x ) to get x by itself:
2x ( /2 ) = 10 ( /2 )
x = 5
Answer:
x=5
Step-by-step explanation:
Step 1:Using the distributive property on the right side of the equation
8x+2=2x+4(x+3)
8x+2=2x+4x+12
Step2:Combining the like terms on the right side if the equation (Since there are no like terms on the left side) :
8x+2=6x+12
Step 3: Using the inverse operations to get the variables on the left side and the constants on the right side of the equation :
8x-6x=12-2
Step4: Using inverse operation to solve for the variable of interest which is 'x':
2x=10 (Dividing both sides by two sides by 2)
x=5
