2(3x+2)=4(x+4)
Then distribute to remove the parentheses, which would equal:
6x + 4 = 4x + 16
Then move constants on one side, variables on the other:
6x - 4x = 16 - 4
Then collect like terms:
2x = 12
Then divide both sides which will get you:
x = 6

A city issues 3-digit license plates for motorized scooters. The digits 0-9 are chosen at random by a computer program. What is the probability that a license plate issued meets each set of criteria
Answers
The probability of a license plate meeting all the given criteria is approximately 0.0000126, or [tex]1.26 x 10^{-5[/tex].
Given that: A city issues 3-digit license plates and digits are 0 to 9.
Having all different digits:
To calculate this probability, use the same approach as before:
Number of favourable outcomes = 10 × 9 × 8
Total number of possible outcomes = 10 × 10 × 10
Probability = (Number of favourable outcomes) / (Total number of possible outcomes)
Probability = (10 × 9 × 8) / (10 × 10 × 10)
Probability = 720 / 1000
Probability = 0.72 (*)
Having at least one even digit:
So, the license plate must have all odd digits (1, 3, 5, 7, or 9).
Number of favourable outcomes = 5 × 5 × 5
Total number of possible outcomes = 10 × 10 × 10
Probability = (5 × 5 × 5) / (10 × 10 × 10)
Probability = 125 / 1000
Probability = 0.125 (1)
Now, the probability of having at least one even digit is the complement of the above probability:
Probability of having at least one even digit = 1 - 0.125
Probability = 0.875 (2)
Having the digits in ascending or descending order:
Ascending: 012, 123, 234, 345, 456, 567, 678, 789
Descending: 987, 876, 765, 654, 543, 432, 321, 210
Total favourable outcomes = 8 + 8
Total favourable outcomes = 16
Probability = 16 / 1000
Probability = 0.016 (3)
Having a specific digit in a specific position:
Let's say want the digit 7 to be in the first position.
Number of favourable outcomes = 1
Total number of possible outcomes = 10 × 10
Probability = 1 / 100
Probability = 0.01 (4)
Now, to find the probability of all criteria being met simultaneously, multiply the individual probabilities:
Probability of meeting all criteria = Probability (1) × Probability (2) × Probability (3) × Probability (4)× Probability (*)
Probability of meeting all criteria = 0.125 × 0.875 × 0.016 × 0.01 × 0.72
Probability ≈ 0.0000126
Hence, the probability of a license plate meeting all the given criteria is approximately 0.0000126.

Ammar hikes 2 3/4 miles of nature trail in 1 hour and 15 minutes. 4
How many miles of trail does Ammar hike per hour?
Answers
Answer:
.42 mph
Step-by-step explanation:
The problem tells us theres 2.75/1.15 miles/hour. And we want to know x/1 miles/hour. To do this you cross-multiply using whats been referee to as the butterfly method. So take 2.75*x=1.15*1. Then you simplify and get 2.75x=1.15. To get x along you must divide which leaves you with. X=.4182(rounded). So you can go .42 miles per hour.

Jill spent 12% of her money on a book. After buying the book, she had $120.12. How much money did Jill have before buying the book?
Answers
Answer:
Jill had $136.50 before buying the book.
Step-by-step explanation:
Let x be the total amount that Jill had
Then 12% of x is 0.12x
Jill was left with $120.12 after buying the book
Subtracting the cost of book from the total amount will given us the remaining amount.
Which means
[tex]x - 0.12x = 120.12\\0.88x = 120.12\\x = \frac{120.12}{0.88} \\x = 136.50[/tex]
Hence,
Jill had $136.50 before buying the book.

Hiran invests 20 000 rupees in an account for 3 years at 1.5% per year compound interest.
Work out the total amount of money in the account at the end of 3 years.
Give your answer to the nearest rupee.
Answers
Answer:
There will be 20 914 rupees in the amount at the end of 3 years.
Step-by-step explanation:
The amount of rupes after t years in compound interest is given by:
[tex]A(t) = A(0)(1+r)^{t}[/tex]
In which A(0) is the initial amount and r is the interest rate, as a decimal.
Hiran invests 20 000 rupees in an account for 3 years at 1.5% per year compound interest.
This means that [tex]A(0) = 20000, r = 0.015[/tex]. So
[tex]A(t) = A(0)(1+r)^{t}[/tex]
[tex]A(t) = 20000(1+0.015)^{t}[/tex]
[tex]A(t) = 20000(1.015)^{t}[/tex]
Work out the total amount of money in the account at the end of 3 years.
This is A(3). So
[tex]A(3) = 20000(1.015)^{3} = 20913.6[/tex]
Rounding to the nearest rupee.
There will be 20 914 rupees in the amount at the end of 3 years.

Make x the subject of the formula 7 + x = t
Answers
Answer:
x = t-7Step-by-step explanation:
[tex]7 + x = t[/tex]
Move 7 to the right side.
Note : That when a number crosses an equality sign , the sign changes.
[tex]x = t - 7[/tex]
Answer:
x=t-7
Step-by-step explanation:
To make x the subject of the formula 7 + x = t
What we mean is that we want x to stand alone.
So if we want x to stand alone then we will subtract both sides by 7 to make the x stand alone.
-7+7+x=t-7
x = t - 7
So now the final answer becomes;
x = t - 7

Find the angle of elevation if the building is 653 feet tall and the observer is 150 feet from the building. Round to the nearest tenth of a degree
Answers
Answer:
Angle of elevation = 77.1°
Step-by-step explanation:
The formula to solve for angle if elevation is given below as:
tan θ = Opposite/ Adjacent
Where
Opposite = Height of the building = 653 ft
Adjacent = Distance from the building = 150 ft
θ = Angle of Elevation = ?
Hence:
tan θ = 653ft/150ft
θ = arc tan (653ft/150ft)
= 77.063069956°
Approximately to the nearest tenth = 77.1°

d. V = π(x^3 + 90x^2 + 2,400x + 20,000)
Step-by-step explanation:
volume of cylinder = πr^2h
We have r = x + 20; h = x + 50
V = π(x + 20)^2(x + 50)
V = π(x^2 + 40x + 400)(x + 50)
V = π(x^3 + 50x^2 + 40x^2 + 2000x + 400x + 20,000)
V = π(x^3 + 90x^2 + 2,400x + 20,000)
A blueprint of an apartment is shown below. What is the actual length of the longest wall in the living room in feet? 0.5 inch : 6 feet Living Room Bedroom Bath 1.5 in.
Answers
Answer:
36 feet long.
Step-by-step explanation:
If the longest wall in the living room is referring to the side that I have drawn over in white and red in the attached image, or if it is the leftmost wall, then that wall is 36 feet long. For every half inch, it is 6 feet, so because there are 6 'half inches' in 3, you multiply 6 feet by the 6 half inches there are, and get 36. There are simpler ways to solve it but I can't take a picture of my work, so I hope this helps. Good luck.
The actual length of the longest wall in the living room is 36 feet.
The blueprint is a scale drawing of the apartment. A scale drawing is a smaller diagram of a large image. A scale drawing is reduced by constant dimensions.
Looking at the given image, the longest wall is 3 inches.
The length of the longest wall in the apartment : (3 in x 6) / 0.5
=18 / 0.5
= 36 feet
