Stephanie earned 8 points for every book she read over the summer. The equation y = 8x represents Stephanie's points based on the number of books she read.
Use the table and equation to complete the statements and find the number of books Stephanie read.
1. Stephanie earned 72 points. Did she read fewer than 2 books, between 2 and 5 books, between 5 and 6 books, or more than 7 books? Explain how you know.
2. The equation y = 8x gives the points, y, earned by reading x books.
Use this equation to find the number of books Stephanie read to earn 72 points. Show your work.
(here are the tables)(plz answer both and dont be greedy as * and say i d k and get pts!)
Answers
Answer: multiply 8 on all x number of books read
Step-by-step explanation:
1 is 8 because 8 × 1 is 8
2 is 16 because 8 × 2 is 16
3 is 24 because 8 × 3 is 24
4 is 32 because 8 × 4 is 32
5 is 40 because 8 × 5 is 40
6 is 48 because 8 × 6 is 48
7 is 56 because 8 × 7 is 56
8 is 64 because 8 × 8 is 64
9 is 72 because 8 × 9 is 72
10 is 80 because 8 × 10 is 80
1. If Stephanie had read fewer than 2 books, she would have earned less than 16 points.
2. Stephanie read 9 books to earn 72 points.
What is an equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
1. To determine the number of books Stephanie read, we can plug in the number of points she earned, which is 72, into the equation y = 8x and solve for x:
72 = 8x
Dividing both sides by 8, we get:
x = 9
So, Stephanie read 9 books to earn 72 points.
If Stephanie had read fewer than 2 books, she would have earned less than 16 points (since 8 points per book multiplied by 2 books is 16 points).
Similarly,
If Stephanie had read between 2 and 5 books, she would have earned between 16 and 40 points.
If Stephanie had read between 5 and 6 books, she would have earned between 40 and 48 points.
If Stephanie had read more than 7 books, she would have earned more than 56 points.
2. The given equation is as follows:
y = 8x
Substitute the value of y = 72 in the equation,
72 = 8x
Dividing both sides by 8, we get:
x = 9
Therefore, Stephanie read 9 books to earn 72 points.

Answer:
32
Step-by-step explanation:

The required smallest natural number value of n that will make each number rational is 1.
60+n and 2n+28, the smallest natural value of n that will make each number rational is to be determined.
Rational numbers are numbers that can be structured in the form of the fraction of integers. Eg- 5/6, 2/3, etc.
Here,
the natural number starts with 1, 2, 3, ... and so on.
The smallest natural number is n = 1
Now, putting n = 1 in the expressions,
60 + 1 and 2*1 + 28
61 and 30
both are rational numbers,
Thus, the required smallest natural number value of n that will make each number rational is 1.

Starting with 0.00082350:
Move the decimal point four places to the right:
0.00082350 becomes 8.2350
Now, we have 8.2350 as our number.
To determine the power of 10 needed to represent this value.
Since we moved the decimal point four places to the right, we raise 10 to the power of -4:
8.2350 x 10⁻⁴.

As you can see, my red numbers are 27 / 32 / 37 / ? / 47. You need to solve for the missing number. This is pretty easy. Each number is five digits apart, so the answer here is “42.” Jot it down.
Now solve for blue. I have 33 / ? / 36 / 39 / 43. This is a bit trickier since there isn’t a simple difference between each one. Working backward helps. 43 is four digits higher than 39; 39 is three digits higher than 36. Working back we can see the pattern. The answer is “34” which is two digits lower than 36, and one digit higher than 33.
