(7h + 7) + (7h + 8)
........
Answer:
14h+15
Step-by-step explanation:
(7h + 7) + (7h + 8)
First simplify
Eliminate redundant parentheses
(7h+7)
7h+7+7h+8
Add the numbers
7h+(7)+7h+(8) . 7+8=15
7h+15+7h
Combine like terms
(7h)+15+(7h) (7h)+(7h)=14h
14h+15
The answer would be 14h+15
Jayson reads the first 48 pages of a 480-page book in 3 days. Marcus reads the first 50 pages of a 400-page book in 4 days. Nina reads the first 120 pages of a 600-page book in 5 days. If they continue to read at these rates, who will finish first?
Answer:
Nina will finish first.
Step-by-step explanation:
Let's calculate how many pages each person reads in one day:
Jayson ⇒ 48 pages / 3 days = 16 pages/dayMarcus ⇒ 50 pages / 4 days = 12.5 pages/dayNina ⇒ 120 pages / 5 days = 24 pages/dayThen we divide the number of pages of each book by reading speed of the respective person:
Jayson ⇒ 480 pages ÷ 16 pages/day = 30 days Marcus ⇒ 400 pages ÷ 12.5 pages/day = 32 days Nina ⇒ 600 pages ÷ 24 pages/day = 25 daysThus Nina will take the shortest time finishing her book.

Daren draws a scale model of the Statue of Liberty
that is 15 inches tall. If the Statue of Liberty is 305
feet tall, what is the scale of the model?
Answer: 1525
Step-by-step explanation:
Explanation:
One way we can do this is to divide the hight of the Statue by the model height:
305ft 1525ft
20in = 1 in
And so for every inch of the model, it represents 15.25 feet.
Solve for x.
A)-6
B)-9

If you ask the first 50 females who enter a restaurant to complete a survey about their experience, who is the sample?
Answer:
the first girl
Step-by-step explanation:
because the first girl to take the survey is a sample but the rest that follows are just extras(can i get brainliest pls)
The sample in this scenario would be the first 50 females who enter the restaurant and are asked to complete a survey about their experience. These 50 females form a subset of the entire population of females entering the restaurant during that specific period.
A sample is a smaller group selected from a larger population for the purpose of gathering information or conducting research. It is often used in situations where it is impractical or impossible to survey the entire population. By surveying this sample of 50 females, the restaurant may gain insights into the experiences and opinions of their female customers.
It's important to note that the sample should ideally be randomly selected to ensure that it represents the population fairly. In this case, if the first 50 females entering the restaurant are chosen randomly, they can provide valuable feedback on their overall experience, which may help the restaurant make improvements or gain valuable insights into their customer base.

Find the greatest common factor (GCF) of 65 and 55.
The greatest common factor of 65 and 55 is 5 because 5 is the highest number that is divisible by both numbers.
What is the greatest common factor?The greatest common factor is the largest positive number which can be divided into given numbers evenly.
In mathematics, the largest positive integer that divides each of the integers is known as the greatest common divisor of two or more integers that are not all equal to zero. The greatest common divisor of two integers is x and y.
Given that the two numbers are 65 and 55. The greatest common factor is the largest number which is divided into both numbers.
65 = 13 x 5
55= 11 x 5
The greatest common factor is,

What is the greatest common factor of 10, 20, and 50?
Answer:
10
Step-by-step explanation:
first you need to find the prime factors of the three numbers
ex:
prime factor of 18= [tex]2*3*3[/tex]
prime of 24=[tex]2*2*2*3[/tex]
there is one 2 and one 3 in common
greatest common multiple 2*3=6
so the greatest common multiple is ten because it is the only one that can divide between all three evenly.
[tex]10=10/10=1\\20=20/10=2\\50=50/10=5[/tex]
so 10 is your answer

B) x= 1/4
C) No solutions
D) x = 3 or x = -4
Answer:
A) x = 3/2 or x= 1/4
Step-by-step explanation:
Solve for x
|3x − 2| = |x + 1|
Rewrite the absolute value equation as four equations without absolute value bars.
3x − 2 = x + 1
3x − 2 = − (x + 1)
− (3x − 2) = x + 1
− (3x − 2) = − (x + 1)
After simplifying, there are only two unique equations to be solved.
3x − 2 = x + 1
3x − 2 = − (x + 1)
Solve 3x − 2 = x + 1 for x.
Move all terms containing x to the left side of the equation.
2x − 2 = 1
Move all terms not containing x to the right side of the equation.
2x = 3
Divide each term by 2 and simplify.
