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

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

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.
Jenya answered 24 out of 30 questions correctly on her math test and 21 out of 25 questions
correctly on her science test. On which test did she score higher?
Answer:
Science Test
Step-by-step explanation:
Math test:
24/30 so divide 24 by 30 to see the percentage she got, which is 80%
Science test:
21/25, same process as before, 21 divided by 25 is 84%
Therefore, she scored higher on the science test.

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

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
