Angie has already written 19 pages, and she expects to write 1 page for every additional
hour spent writing. How many hours will Angie have to spend writing this week in order to
have written a total of 28 pages?
Answers
Answer:
[tex]9[/tex]
Step-by-step explanation:
[tex]28 - 19 = 9[/tex]
9 hours
Explanation:
What we know:
- Angie has already written 19 pages
- Angies writes 1 page per hour
First, we can create the following equation to model this scenario:
Let x be equal to the number of hours that pass.
Total number of pages=1x+19
Now, because Angie wants to write 28 pages in total, we can plug that into the left side of the equation and solve for x, the number of hours.
28=1x+19
Subtract both sides by 19
28-19=1x+19-19
9=1x
x=9
Therefore, Angie would have to spend 9 hours to write a total of 28 pages.

Jessica is selling books during the summer to earn money for college. She
earns a commission on
each sale but has to pay for her own expenses.
After a month of driving from neighborhood to neighborhood and walking
door-to-door, she figures out that her weekly earnings are approximately a
linear function of the number of doors she knocks on.
She writes the equation of the function like this: E(X) = 10x - 30, where x is the
number of doors she knocks on during the week and E(x) is her earnings for
the week in dollars.
Which of the following are reasonable interpretations of the y-intercept of
Jessica's function?
Check all that apply.
A. She can earn $10 per week even if she does not knock on any
doors.
B. She will lose $10 per week if she does not knock on any doors.
C. If she does not knock on any doors at all during the week, she will
lose $30.
D. Her expenses are $30 per week.

Jesse went to the store with a total of $45. He bought a
hat that cost $12, a hat for $10 and some ties. If each
tie cost $4. What is the most amount of ties he can buy?
asap pls
Answers
Answer: He can buy 5 ties
Step-by-step explanation:
12+10=22. 4x5=20. 22+20=42. If you add 1 more tie, you will have $46, so you cannot add one more tie. So the most amount of ties he can buy is 5 ties, with $3 left to spare.

To solve a multi-variable problem, you need to isolate single variables. To do this, there are two ways to do it. One way you eliminate one of the variables and the other you substitute.
In this example, you are being asked to eliminate one of the variables. To do this, you multiply 2x+2y= 12 by 2 and get 4x+4y = 24.
See how now both equations contain a 4y?
Using this you can subtract one equation from the other.
5x+4y=28
- 4x+4y=24
And then you get x=4
To get the other variable, you substitute 4 in for x (in one of the equations) and then solve for y.
2(4) + 2y =12
8+2y= 12
2y=4
y=2
Therefore, x = 4 and y = 2

C. 3x2 - 10x + 1
D. 3x2 + 4x + 1
Answers
Step-by-step explanation:
(f - g)(x)
= f(x) - g(x)
= (3x² - 3x + 5) - (-7x + 4)
= 3x² - 3x + 5 + 7x - 4
= 3x² + 4x + 1. (D)

erica planted 8 cucumber plants each plant had 37 green cucumbers how many cucumbers are on the 8 plants altogether
Answers
Answer:
296 Cucumbers
Step-by-step explanation:
I think it maybe 296 because since each plant produced 37 cucumbers and there are 8 plants you have to do 37 x 8 and you get 296.
Answer: 296
If you multiply the 37 green cucumbers each by the 8 cucumber plants they grew from, you'd end up with 296 green cucumbers altogether.

Answer:-43 + 9x = 0
Step-by-step explanation:Simplifying
9x + -43 = 0
Reorder the terms:
-43 + 9x = 0
Solving
-43 + 9x = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '43' to each side of the equation.
-43 + 43 + 9x = 0 + 43
Combine like terms: -43 + 43 = 0
0 + 9x = 0 + 43
9x = 0 + 43
Combine like terms: 0 + 43 = 43
9x = 43
Divide each side by '9'.
x = 4.777777778
Simplifying
x = 4.777777778
