1. Pilar and her sister Marisol live near the beach. Pilar has 80 seashells in her collection when Marisol started collecting seashells. Marisol started with zero seashells in her collection.
• Pilar adds 10 seashells to her collection each week for x weeks.
• Marisol adds 20 seashells to her collection each week for x weeks.
(a) Write an inequality to represent the situation when the number of seashells in Marisol's collection is greater than the number of seashells in Pilar's collection.
(b) Solve the inequality in part (a) for the x. Show your work and explain your answer.
Answer:
a. 20x > 10x + 80
b. •20x > 10x + 80
• Subtract 10x from both sides: 20x -10x > 10x + 80 - 10x
• Simplify: 10x > 80
• Divide both sides by 10: 10x/10 > 80/10
• Simplify: x > 8
Step-by-step explanation:
10x + 80 = number of seashells Pilar has.
20x = number of seashells Marisol has.
answer for a: 20x > 10x + 80
answer for b: 20x > 10x + 80
• Subtract 10x from both sides: 20x -10x > 10x + 80 - 10x
• Simplify: 10x > 80
• Divide both sides by 10: 10x/10 > 80/10
• Simplify: x > 8

Add spaces before and after slashes d. Use a clean and neat overall format Please select the best answer from the choices provided A B C D
Answer:
b.
Use special characters like italics and underlining
Step-by-step explanation:
i took the test
When it comes to scannable resumes, it is not recommended that you b. Use special characters like italics and underlining.
How should scannable resumes be designed?Because they are to be scannable, they are not to have complicated characters that might be unscannable such as special characters and underlining.
They should be printed on white paper using black ink only and should have a format that is best described as being neat and clean.

distance between (4, –1) and (8, –1)?
Answer: 4
Step-by-step explanation: compute the distance between (x1, y1), (x2, y2):
(8 -4)² + [ -1 - (-1) ]² = 4
Answer:
4
Step-by-step explanation:
X1 = 4
X2= 8
Y1 = -1
Y2= -1
Distance Formula = √(X2-X1)² + (Y2-y1)²
Step 1. calculate (X2-X1)²
(8 - 4)2 = 16
Step 2. calculate (Y2-Y1)²
(-1 - -1)2 = 0
Step 3. calculate √16 + 0

Five times the smallest of three consecutive odd integers is seven more than twice the largest. Find the largest
integer.
// we also have to se only one variable to solve this equation.
like this x+3 would be okay
Answer: 9
Step-by-step explanation:
Let the consecutive odd numbers be y, y+2 and y+4.
Five times the smallest of three consecutive odd integers is seven more than twice the largest. Find the largest integer can be expressed as:
5y = 2(y+4) + 7
5y = 2y + 8 + 7
5y = 2y + 15
5y - 2y = 15
y = 3
The smallest odd number is 5
The largest integer will be:
= y + 4
= 5+4
= 9

Janelle bought a notebook and three mechanical pencils for $4.75, while Sharai bought two notebooks and one mechanical pencil for $3.25. What is the cost of a mechanical pencil?
Answer:
mechanical pencil costs $1.25 each
Step-by-step explanation:
First, lets define our variables:
notebook = n
mechanical pencil = p
Next, we need to set up two equations using the information given:
n + 3p = 4.75
2n + p = 3.25
Next, lets take the first equation and solve for n.
n+ 3p = 4.75
n = 4.75 - 3p
Now we can replace "n" in the second equation with "4.75 - 3p".
2n + p = 3.25
2(4.75 - 3p) + p =3.25
9.5 - 6p + p = 3.25
9.5 - 5 p = 3.25
9.5 = 5p + 3.25
5p = 6.25
p = 1.25
Finally, we can go a step further and solve for "n" by plugging "p" back into the second formula:
n = 4.75 - 3(1.25)
n = 1.0
I hope this helps!

PLEASE HELP!! Identify the polygon and determine if it is concave or convex
Answer:
Concave
Step-by-step explanation:
Concave means that there's an indent in the polygon somewhere, for example an octagon would not be a concave shape because it doesn't have an indent in it anywhere. Hope that makes sense
Rewrite the following expression using the additive inverse property: -21 - (-50)
Answer:
50 - 21
Step-by-step explanation:
Solve, then write, each equation in slope intercept form.
Answer:
1) (3,5)
2) (4,-7)
3) (6,4)
4) (-4,-3)
Step-by-step explanation:
1)
Subtract y from both sides of the equation.
x = 8 − y
x − y = −2
Replace all occurrences of x in x − y = −2 with 8 − y.
x = 8 − y
(8 − y) − y = −2
Subtract y from −y.
x = 8 − y
8 − 2y = −2
Solve for y in the second equation.
x = 8 − y
y = 5
Replace all occurrences of y in x = 8 − y with 5.
x = 8 −(5)
y = 5
Simplify 8 −(5).
x = 3
y = 5
Slope = (3,5)
2)
Multiply each term by 2 and simplify.
2x+y=12

y=21
Divide each term by −3 and simplify.
y = −7
Substitute the value found for y into one of the original equations, then solve for x.
x = 4

Move all terms not containing a variable to the right side of the equation.
−2x+y=5
y+3x=−15
Reorder the polynomial.

Add the two equations together to eliminate y from the system.
−2x+y=5 + −3x−y=15−5x=20
Divide each term by −5 and simplify.

(a+b)^3+8c^3
Answer:
(a + b + 2c)(a² + 2ab + b² - 2ac - 2bc + 4c²)
Step-by-step explanation:
Given
(a + b)³ + 8c³ ← this is a sum of cubes and factors in general as
a³ + b³ = (a + b)(a² - ab + b²)
Thus
(a + b)³ + 8c³
= (a + b)³ + (2c)³
= (a + b + 2c)( (a + b)² - 2c(a + b) + (2c)² )
= (a + b + 2c)(a² + 2ab + b² - 2ac - 2bc + 4c²)
help me with this plzzzzzzzzz
Answer:
x=1, y=2
Step-by-step explanation:
Answer: x = 13 and y = -2
Step-by-step explanation:
You need to use the elimination method for each equation, so that means being able to cross them out by equaling them to 0. You can choose x value or the y value, since you need to do 2 things to the y value I will show you an easier way with the x value since it is equal to one in the top equation.
Looking at the bottom equation, you need to find a way to set the x equation to cross 2x out making it 0. Removing x from this, how can you make 2 end up being 0? Subtract 2 from it, but x is not -2 on the first equation, so you have to times everything in that equation by -2 to make x -2.
so basically,
-2(x + 3y = 7)
your new equation is
-2x -6y = -14
put your other equation under it to eliminate the x value finally.
-2x -6y = -14
2x + 2y = 6
so you only need to combine like terms. X is no longer included because x is eliminated.
-4y = 8
divide to find the value of y
Y = -2
plug your newly found equation in for y in the original equation (either one is fine.
x + 3(-2) = 7
x -6 = 7
add 6 to both sides
x = 13
