2x=3
After solving the equation, x = 3/2 is the value of x in 2x = 3.
⇒ 2x = 3
⇒ x = 3/2
How to solve an equation?
To solve linear equations, utilize the steps that are provided below.
Remove parentheses from each side of the equation and combine similar terms to make it simpler.To separate the variable term on one side of the equation, use addition or subtraction.To find the variable, use division or multiplication.The common denominator can be multiplied by each side of the equation to eliminate fractions.Lets take an example of solve z for 7z – (3z – 4) = 12
Here is no multiplication or division, so this will be easy to solve
⇒ 7z – (3z – 4) = 12
⇒ 7z – 3z + 4 = 12
⇒ 4z = 12 – 4
⇒ 4z = 8
⇒ z = 8/4
⇒ z = 2
See, that was so simple, using the mentioned methods, every linear equation can be solved easily.

Bron
b. How many hours did he take to drive one mile?
Graham drove 32.58 miles in one hour and it took 1.84 minutes to drive a mile
Miles Graham drove in 13 hours = 423 miles
Unitary method: A single unit's value can be determined from the values of multiple units, and multiple units' values can be determined from the values of single units using the unitary technique. It is a technique that we employ for the majority of math calculations.
Part a:
Miles driven in one hour = Total miles driven/Total no. of hours taken

How long would it take to double your principal in an account that pavs 6.5 % annual interest compounded continuously?
It will take 4.63 years to double the principal.
The formula for calculating the amount (A) on a principal (P) invested at the rate of r%, compounded continuously after t years is-
A = P[tex]e^{rt}[/tex]
Here r = 6.5%
= 0.065
Let the principal amount be P,
then the amount after t years = 2P
A = P[tex]e^{rt}[/tex]
2P = P[tex]e^{rt}[/tex]
2P/P = [tex]e^{rt}[/tex]
2 = [tex]e^{0.065t}[/tex]
Taking log on both sides-
Log 2 = log [tex]e^{0.065t}[/tex]
Log 2 = 0.065t log e
Log 2 = 0.065t
0.65t = Log 2t
= log 2/ 0.065t
= 0.301/ 0.065 t
= 4.63
Thus, it will take 4.63 years to double the principal.

The length of a rectangular garden is 5 feet less than twice its width. If the total distance around the garden is 44 feet, what are the length and width of the garden?
Answer: 78
Step-by-step explanation: multiply 44 by 2 because there are two sides on the rectangle and then you add 5 and 5 because yet again there are two sides so when you get your answer subtract 10 from the 88 and then you get 78 there is your explanation and equation
Rectangle with perimeter 44 ft has its length and breadth 13 ft and 9 ft respectively.
Dimension of rectangle : 13 × 9
Given, that perimeter of rectangle is 44 ft .
Now, perimeter of rectangle is given by:
P = 2(l + b)
l = Length of rectangle .
b = Breadth of rectangle.
Let the breadth of rectangle be 'x' m.
Then length will be (2x -5) ft.
Substitute the values in the perimeter formula,
[tex]44 = 2(x + 2x -5)\\22 = 3x -5\\x = 9[/tex]
Thus the breadth of rectangle is 9 ft .
Length of rectangle is 5 ft less than twice its breadth.
Length = 2(9) - 5
Length = 13 .
Therefore the dimensions of rectangle is 13 × 9.

Find the amount in a continuously compounded account for the given conditions.
principal: $ 6000 ; annual interest rate: 6.8 % ; time: 10 years
The amount after 10 years is $11,842.43
In continuous compounding the number of times by which compounding occurs tends to infinity.
In order to calculate the amount use the following formula
A= Pe^rt
where P represents the initial amount, e is the mathematical constant having value 2.7182, r is the rate of interest and t is the time period
Here the principal amount is $6000, r is 6.8 and time period t is 10 years
A = $6000 x 2.718⁽¹⁰ ˣ ⁶·⁸ %⁾
A = 6000 x 2.718⁽¹⁰ ˣ ⁶·⁸÷¹⁰⁰⁾
A = 6000 x 2.718 x 0.68
A = $ 11,842.43
Therefore the total amount calculated after 10 years is $ 11,842.43

The question is 0.65 into a fraction can anyone help me figure this out?
Answer:
If 0.65 is a decimal, then as a fraction it would be 65/100. This can be simplified though. 65 and 100 are both divisble by 5.
100 divided by 5 is 20 and 65 divided by 5 is 13. This is as simplified as it can go, so the answer is 13/20.

Step-by-step explanation:
Colton is 1.55 meters tall. At 1 p.m., he measures the length of a tree's shadow to be 44.35 meters. He stands 39 meters away from the tree, so that the tip of his shadow meets the tip of the tree's shadow. Find the height of the tree to the nearest hundredth of a meter.
If Colton is 1.55 meters tall. At 1 p.m., he measures the length of a tree's shadow to be 44.35 meters. the height of the tree to the nearest hundredth of a meter. is 12.85 meters.
HeightFirst step is to find the distance that he is horizontally from the top of the shadow
Distance = 44.35 meters - 39 meters
Distance = 5.35 meters
Second step is to make use of equal proportion and find the height
5.35/ 1.55 = 44.35/x
5.35x = 1.55 × 44.35
x= 1.55 × 44.35 /5.35
x= 12.849
x= 12.85 meters (Approximately)
Therefore If Colton is 1.55 meters tall. At 1 p.m., he measures the length of a tree's shadow to be 44.35 meters. the height of the tree to the nearest hundredth of a meter. is 12.85 meters.

10) Your friend has a play tepee. The tepee
has a radius of 4 feet and a height of 6
feet. What is the volume of the tepee?
The volume of the tepee is 100.48 feet³
The formula for the volume of tepee is same as the volume of cone which is given as :
V = 1/3 πr²h (1)
where V = volume
r = radius of the tepee
h = height of the tepee
According to the question we have been given that
radius = 4 feet
height = 6 feet
Putting the required values in equation (1) we get
V = 1/3 π (4)²(6)
= 1/3 (3.14)(96)
= 301.44/3

Three orders are placed at a sandwich shop. Four sandwiches, two beverages, and
one salad costs $40; two sandwiches, one beverage, and two salads costs $26; and
three sandwiches, three beverages, and two salads costs $38. How much does each
item cost?
The respective prices are given below as
The price of the sandwich is 20/3 dollars.
The salad may be purchased for a price of $16/3.
There is a fee of $2 for the drinks.
How can you build equations that are simultaneous?Let's say that the price of the sandwich is x.
Allow the price of salad to equal y.
Allow the price of drinks to equal z.
The new total for this meal is $46. It includes three sandwiches, three beers, and two salads. Thus;
3x + 3y + 2z = 40 ——- (eq 1)
The price of $29 covers two sandwiches, two drinks, and one salad.
Thus;
2x + 2y + z = 26 ——-(eq 2)
It will cost you $54 for four sandwiches, one drinks, and three salads. Thus;
4x + y + 3z = 38 ———-(eq 3)
The following are the results of concurrently solving the three equations:
x = 20/3
y = 16/3
z = 2
Therefore, the following is how much each item costs:
There is a charge of $20/3 for the sandwich.
The salad may be purchased for a price of $ 16/3.
There is a fee of $2 for the drinks.

We need to know about logarithm to solve this problem. The greatest integer that is less than the value of log 5 is 0.
Logarithm is the exponent that is raised to a base to get a certain number. There are a few rules of algorithm, log a+ log b can be written as log ab, log a -log b can be written as log a/b, when a number whose logarithm is being calculated is raised to a certain power then the power can be directly multiplied to the log itself. Logarithm when written as log has a base of 10, the logarithm of a number that is same as it's base is always 1, the log of 1 is always zero, because any nonzero number raised to 0 is 1.We will find the value of log 5 first and then choose the nearest integer that is less than log 5.
log 5=log 10/2 =log 10-log 2=1-0.30=0.7
Therefore the greatest integer that is less than the value of log 5 is 0.
