Two more than a certain number is 15 less than the product of 7/8 and the number
Final answer:
The algebraic equation derived from the statement is solved by isolating 'x' after moving terms to either side of the equation and combining like terms. The solution to the equation is x = -136, which represents the certain number in question.
Explanation:
Solving the Algebraic Equation
The question can be translated into an algebraic equation. Let's call the certain number 'x'. According to the problem, 'two more than a certain number is 15 less than the product of 7/8 and the number'. We can write this as:
x + 2 = (7/8)x - 15
To solve for x, we can start by moving all terms involving x to one side of the equation and the constant terms to the other side, aiming to isolate x:
Subtract (7/8)x from both sides to get x - (7/8)x + 2 = -15.
Combine like terms, remembering that x is the same as (8/8)x, which results in (1/8)x + 2 = -15.
Subtract 2 from both sides to get (1/8)x = -17.
Multiply both sides by 8 to find x. Therefore, x = -136.
The certain number in the equation is -136.
1. If one letter is chosen at random from the word combed, what is the probability that the letter chosen will be a "d"?
2. The sides of number cube have the numbers 2,4,8,9,4, and 7. If the cube is thrown once, what is the probability of rolling a 7?
3. A bag contains 12 red marbles, 10 green marbles, 2 yellow marbles, 19 blue marbles, and 9 purple marbles. What is the probability of pulling out a green marble?
Answer:
Probability that the chosen letter is d is [tex]\frac{1}{6}[/tex]Probability of rolling a 7 is [tex]\frac{1}{6}[/tex]Probability of picking a green is [tex]\frac{5}{21}[/tex]Step-by-step explanation:
Probability of choosing d in the word "combed"Given:
Alphabet: d
Word: combed
First, we note down the length of the word "combed";
The length is 6 characters
The we check the number of occurrence of d in the word "combed"
Occurrence of d = 1
Probability is then calculated as;
Probability of choosing d = [tex]\frac{Number of Occurrence}{Total Observation}[/tex]
By Substitution; Probability = [tex]\frac{1}{6}[/tex]
Probability of rolling a 7 in a cube of side numbers 2,4,8,9,4, and 7Given:
Roll number = 7
Sample Space= {2,4,8,9,4, 7}
Sample Size, n(S) = 6
We check the number of occurrence of 7 in the sample space
Number of occurrence = 1
Probability is then calculated as;
Probability of rolling a 7 = [tex]\frac{Number of Occurrence}{Sample Size}[/tex]
By Substitution; Probability = [tex]\frac{1}{6}[/tex]
Probability of pulling out a green marbleGiven
Red = 12
Green = 10
Yellow = 2
Blue = 19
Purple = 9
Total = 12 + 10 + 2 + 19 + 9 = 42
Probability of picking a green marble is then calculated as;
Probability of choosing d = [tex]\frac{Number of Green}{Total}[/tex]
By Substitution; Probability = [tex]\frac{10}{42}[/tex]
Probability = [tex]\frac{5}{21}[/tex]

List three numbers that are divisible by 3, 4 and five
To find numbers divisible by 3, 4, and 5, we need to find common multiples of these three numbers. One example is 30, and other possible numbers include 60 and 90.
Explanation:When we need to find numbers that are divisible by 3, 4, and 5, we can look for numbers that are common multiples of these three numbers. In other words, we need to find numbers that can be divided evenly by 3, 4, and 5 without any remainder. Let's take a look at the first few numbers and see if they satisfy this condition.
15: 15 is divisible by 3 (15 ÷ 3 = 5), divisible by 5 (15 ÷ 5 = 3), but not divisible by 4 (15 ÷ 4 = 3 remainder 3), so it is not a solution.20: 20 is not divisible by 3 (20 ÷ 3 = 6 remainder 2), not divisible by 4 (20 ÷ 4 = 5 remainder 0), but divisible by 5 (20 ÷ 5 = 4), so it is not a solution.30: 30 is divisible by 3 (30 ÷ 3 = 10), divisible by 4 (30 ÷ 4 = 7 remainder 2), and divisible by 5 (30 ÷ 5 = 6), so it is a solution.From our analysis, we found that the number 30 is divisible by 3, 4, and 5. We can list two more numbers by finding common multiples of these three numbers.

Customers at an ice-cream shop took a survey. The results showed that 144 customers rates the shop as being "very satisfactory." This number represented 45% of the total number of customers who took the survey. What was the total number of customers who took the survey ? explaination plz
The total number of customers who took the survey is 320 customers
let
x = total number of customers
percentage of "very satisfactory" customers = 45%
Number of "very satisfactory" customers = 144
So,
Number of "very satisfactory" customers = percentage of "very satisfactory" customers × total number of customers
144 = 45% × x
144 = 0.45 × x
144 = 0.45x
x = 144/0.45
x = 320
Therefore, the total number of customers who took the survey is 320

the left and right page numbers of an open book are two consecutive integers whose sum is 329. Find these page numbers.
Follow below steps:
The student is seeking to find two consecutive integers whose sum is 329. This is a mathematics problem and involves understanding of even and odd numbers as well as basic algebra. Since the numbers are consecutive, we can represent them as n and n + 1. The sum of these numbers given in the problem is 329, so we have the equation n + (n + 1) = 329.
Solving this equation:
Combine like terms: 2n + 1 = 329
Subtract 1 from both sides: 2n = 328
Divide both sides by 2: n = 164
Thus, the two consecutive page numbers of the book are 164 and 165

Tom went on a bike ride to the store 3 miles away if it took Time 1/2 hour to get there in 2/3 of an hour to get back what was his average rate of speed miles per hour for the entire trip
In order to achieve the times that he did in going to and from the store, Tom went at an average speed of 5.14 miles per hour.
The store was 3 miles away which means that the distance of the entire trip is:
= Distance going + Distance coming
= 3 + 3
= 6 miles in total
The time he took was:
= Time going + Time coming
= 1/2 hours + 2/3 hours
= 0.5 + 0.67
= 1.17 hours
His average speed for the entire journey is:
= Distance / Time
= 6 / 1.17
= 5.14 miles per hour
In conclusion, Tom's average speed was 5.14 miles per hour.
