9e - 7 = 7e - 11
solve for e
Answer:
e = -2
Step-by-step explanation:
9e - 7 = 7e - 11
Subtract 7e from both side
2e - 7 = -11
Add 7 to both sides
2e = -4
Divide by 2 to isolate e
e = - 2
Answer:
e = -2
Step-by-step explanation:
9e - 7 = 7e -11
9e - 7e - 7 = -11
9e - 7e = -11 + 7
2e = -4
e = -2

Answer:
b = [tex]\sqrt{333}[/tex]
Step-by-step explanation:
1. We can use the Pythagorean Theorem to find the missing side, b.
[tex]14^2 + b^2 = 23^2[/tex]2. (Solving)
Step 1: Simplify both sides of the equation.
[tex](14*14)+b^2 =(23*23)[/tex] [tex]196 + b^2 = 529[/tex]Step 2: Subtract 196 from both sides.
[tex]196 + b^2 - 196 = 529 - 196[/tex] [tex]b^2 = 333[/tex]Step 3: Take square root of both sides.
[tex]\sqrt{b^2} = \sqrt{333}[/tex] [tex]b = \sqrt{333}[/tex]Step 4: Check if solution is correct.
[tex]14^2 + \sqrt{333^2} = 23^2[/tex] [tex](14*14)+(\sqrt{333} *\sqrt{333})=23*23[/tex] [tex]196 + 333 = 529[/tex] [tex]529 = 529[/tex]Therefore, b = [tex]\sqrt{333}[/tex].
Answer:
Step-by-step explanation:
[tex]a^{2} + b^{2} = c^2\\14^2 + b^2 = 23^2\\\\196 + b^2 = 529\\\\b^2 = 333\\b = 18.2482875909[/tex]

Penny reads 11 pages in 1/3 hour. What is the unit rate for pages per hour? For hours per page?
Answer: 33
Step-by-step explanation:
Answer:
33 pages per hour
Step-by-step explanation:
1. To solve for how many pages Penny can read in one hour, we need to write a ratio of pages to hours.
[tex]11: 1/3 = x : 1[/tex]2. Now, 1/3 goes into one, three times. This means that 11 goes into x, three times. We can write "11 goes into x, three times" as: [tex]\frac{x}{11} =3[/tex].
3. (Solving x/11 = 3)
Step 1: Multiply both sides by 11
[tex]\frac{x}{11}*11=3*11[/tex] [tex]x = 33[/tex]Therefore, Penny read 33 pages per hour.

This question has been answered in a secondary question post by the OP.
A school had 180 boys and 240 girls attending
(a) What is the ratio of boys to girls?
(b) What is the ratio of girls to boys?
(c) What is the ratio of students to boys?
(d) What is the ratio of girls to students?
Answer:
a) 3 : 4
b) 4 : 3
c) 7 : 3
d) 4 : 7
Step-by-step explanation:
(just a side note: you can write ratios in fraction form as well!)
To find the ratio between boys to girls, we would write it like this:
180/240 or 180 : 240 or 180 to 240
Although that is right, that isn't simplified.
Thus, we need to find a common factor that both the numerator and denominator share!
180 and 240 are both divisible by 60!
180 ÷ 60 = 3
240 ÷ 60 = 4
Therefore, you would get a simplified ratio of 3 : 4! For every 3 boys. there are 4 girls!
For part b, you simply switch the 4 and 3 around so you get 4 : 3. For every 4 girls, there are 3 boys.
Now part c involves the total amount of students...
Basically, add the number of boys and the number of girls together, and you would get 420.
420 : 120 shows the amount of students there are to boys...but it is not in its simplest form!!
Like we did before, we have to find a common factor between the two...which is 60!
420 ÷ 60 = 7
120 ÷ 60 = 3
Thus, there are 7 students for every 3 boys (7 : 3)
Finally, part d! Simply the ratio:
420 : 240
Divide both by 60 and...
You get 4 :7! For every 4 girls, there are 7 students
Hope this helps! Let me know if you have any other questions :D
Answer:
(a) 3:4
(b) 4:3
(c) 7:3
(d) 4:7
Step-by-step explanation:
(a) 3:4
180:240 = 3:4 (after simplification)
(b) 4:3
240:180 = 4:3 (after simplification)
(c) 7:3
Total number of students = 240 + 180 = 420
420:180 = 7:3 (after simplification)
(d) 4:7
Total number of students = 240 + 180 = 420
240: 420 = 4:7 (after simplification)

At the beginning of the week, Aksa’s parents deposited $20 into Aksa’s lunch account. The amount of money Aksa had left after each day is shown in the table, where x is the number of days and y is the remaining balance.
a. What are the x- and y-intercepts?
b. What do the x- and y-intercepts represent?
Here we need to plot x and y co-ordinates from the given table.
What are x and y co-ordinates and intercepts ?This is 2D co-ordinate geometry here we have an x axis and a y axis we use co-ordinate geometry to plot lines and curves according to the gives question.when the question consist of linear equations they form straight lines and when questions consists of quadratic and higher degree polynomials they form curves.
a. Here the the days are represented by x and remaing balance are represented by y.
So, when x = 0, y = 20 is co-ordinate form we can represent this as (0,20)
similarly the other co-ordinate points are (1,16), (2,12), (3,8), (4,4), (5,0).

Answer:
20) 7/16 = 0.4375
21) 1/6 = 1.6 repeating
22) 2 4/5 = 2.8
23) 98 2/3 = 98.6 repeating
24) 0.8 = 4/5
25) 26 1/5
26) 72.1 repeating = 72 1/9
27) 0.505 = 101/200
Explanation:
To convert fraction into decimal, divide the numerator by the denominator and that's your answer. For example:
7 ÷ 16 = 0.4375.
To convert a decimal into a fraction, place the number after the decimal point over the number place it's in. For example: If you look at 0.8 , 8 is in the tenths place, so you place it over 10 like this 8/10, and then you simplify. Half of 8 is 4 , and half of 10 is 5, so you'd have 4/5.
For #27, since 505 in 0.505 , is in the thousandths place, you'd put it over 1,000 like this 505/1000 and then you simplify. Look at image above to learn how to simplify 505/1000.⤴⤴⤴

Write the verbal phrase

the sum of d and 7
Answer:7
Step-by-step explanation:
I graduate from Harvard
a carpenter is fitting some bookcases to an alcove, using as much of the space as possible from floor to ceiling, a height of 2.5 m. The books to be fitted into the shelves are 210 mm high and a gap of at least 30 mm is necessary above each book so that they can be removed. The shelves are 20 mm thick. The alcove is 1.2 m wide. The bottom shelf should not be less than 300 mm from the ground, as the house-owner cannot bend down easily. How many shelves can be fitted into the alcove?
The number of shelves that fit in the alcove is given by the height of each shelve and the height of the bookshelf above the ground
The number of bookshelves that fit into alcove, is 8 bookshelves
Reason:
Height of the alcove = 2.5 m
Height of the books = 210 mm = 0.21 m
The gap above each book = 30 mm = 0.03 m
The thickness of the shelves = 20 mm = 0.02 m
Width of the alcove = 1.2 m
Height of the bottom shelf above the ground = 300 mm = 0.3 m
Required:
The number of shelves that can be fitted into the alcove
Solution;
Let x, represent the number of shelves that can be fitted into the alcove
We have;
An initial height of the bookshelves above the ground = 0.3 m
Height of a shelve, H = Height of books + Gap above books + Thickness of shelves
Height above ground, including the bottom shelve = 0.3 m
[tex]x = \dfrac{2.5 - (0.3)}{0.02 + 0.03 } = 8\frac{6}{13}\approx 8.46[/tex]Therefore, the maximum number of whole bookshelves that can be fitted into alcove, x ≈ 8 bookshelves

What is the total price of a $45.79 item when a 7% taxe is added
Answer:
$42.58
Step-by-step explanation:
You would multiply the price of the item (45.79) by the percentage as a decimal (0.07) and subtract the product.
in this case:
45.79x0.07 = 3.205 (rounded 3.21)
45.79-3.21 = 42.58
