Samantha paid $10 to join an online book club. Then she paid $3 per e-book that she read. She has spent more than $40. How many e-books did she read? Show how you would set the problem up and the answer. * Your answer Submit Jer submit passwords through Google Forms. This form was created inside of River Grove School District 85.5. Report Abuse
Answer:
13/13.3 or 10
Step-by-step explanation:
You said she paid $10 to join, if she spent at least $40, then we subtract 10, then divide 30 by 3 then you would get 10.
If we don't have to subtract and she spent around $40 on only books, it would be 13/13.3

Edwin and Anthony are building a rectangular deck in their backyard.The Longer side is 2 more than 1/3 the perimeter. The shorter side is 1/10 of the perimeter. Know that the longer side is 9 ft longer than the shorter side. What is the Perimeter of the deck?
Answer: The perimeter is 30ft.
Step-by-step explanation:
Let's define:
L = length of the longer side.
S = length of the shorter side.
P = perimeter
we know that for a common rectangle:
P = 2*S + 2*L
We aso know that:
L = 2ft + (1/3)*P
S = (1/10)*P
L = S + 9ft.
So we have a system, let's find the perimeter only using this system (So i will ignore the equation for the perimeter of a rectangle)
First, we can replace the third equation in the first equation, now we have a system with only two equations:
S + 9ft = 2ft + (1/3)*P
S = P/10
Now we can replace the second equation in the first equation, and get:
P/10 + 9ft = 2ft + P/3
Now let's solve this for P.
9ft - 2 ft = P/3 - P/10
7ft = P( 1/3 - 1/10) = P*( 10/30 - 3/30) = P*(7/30)
(30/7)*7ft = P = 30ft.
The perimeter is 30ft.

(11x - 1)
(20x – 3)
151°
Answer:
x= 1.6 degrees
Step-by-step explanation:
to find the missing angle 180 degrees - 151 degrees
29° is the missing angle at the bottom ryt of the triangle.
all angles in triangle add upto 180°
so, 20x-3°+11x-1°+29°= 180°
31x=180°-25°
x= 1.6°
A polygon with three edges and three vertices is called a triangle.
x=1.6° is its value.
Explain about the triangle?Based on the lengths of its sides, triangles can be categorized into one of three groups: Scalene. Isosceles. Equilateral.
The trigon, a 3-sided polygon, is sometimes (though not often) referred to as a triangle. Every triangle has three sides and three angles, some of which might be the same.
The triangle's angles are created by joining its three sides end to end at a single point. The sum of the three angles of the triangle is 180degrees.
To identify the omitted angle between 180 and 151 degrees
The triangle's bottom right corner lacks a 29° angle.
triangle's angles sum up to 180°
so, 20x-3°+11x-1°+29°= 180°
31x=180°-25°
x =1.6 degree

Trace is at school and wants to send his homing piaeon home for his forgotten Geometry homework. If the coordinates for his home are (-5,5) and his school is at (-1,2), what is the length of his pigeon's flight directly to the house?
Answer: Length= ____ units
Answer:
5 units
Step-by-step explanation:
From the coordinates, we have;
x1 = -5
x2 = -1
y1 = 5
y2 = 2
Now,from the distance formula, distance is;
d=√((x2 - x1)²+(y2 - y1)²)
Plugging in the relevant values, we have;
d = √((-1 + 5)²+(2 - 5)²)
d = √(16 + 9)
d = √25
d = 5

7(x-8)=2x-31
Answer:
x=5
Step-by-step explanation:
7 (x-8)=2x-31
Distribute the 7 to the x and -8 (basically multiple 7 with the x and -8)
7x-56=2x -31
Drag the 2x over to the other subtracting it from 7x.
7x-2x-56=-31
5x-56=-31
Drag the 56 to the other side and add it to -31
5x= -31+56 (or 56-31)
5x= 25
Divide 5x from 25 to get your X
x=25/5
x=5

What is the answer to 3n/7 = 33/70
Answer: [tex]n=\frac{11}{10}[/tex]
Step-by-step explanation:
[tex]\frac{3n}{7}=\frac{33}{70}[/tex]
[tex]\frac{210n}{210}=\frac{231}{210}[/tex]
[tex]n=\frac{11}{10}[/tex]
Lol this question seems simple for a person coming from Calculus only to increase my confidence ; )
3n/7 = 33/70
So to solve this equation , all you have to do is cross multiply the fractions.
3n*70 = 33*7
210n = 231
n = 231 / 210 = 11/10
n = 11/10
