2.35496...
5.4
1.329538...
4.77777...
multi choice*
Answer:
A,C,D
Step-by-step explanation:
Irrational number that keep going and never stop that DONT have a pattern
For example
1/3=0.3
It keeps going on BUT it repeats therefore its rational
Another example
The square root of 13 is 3.6055.......
it keeps going on BUT it doesn't have a pattern therefore its irratianal
convert 0.10606060606......... to a fraction
Answer:
7/66

Answer:
x = (y +2)/3
Step-by-step explanation:
The flowchart is trying to help you see that you "undo" what is done to x, in reverse order.
x is first multiplied by 3, then -2 is added.
First, we want to undo the addition of -2, so we add the opposite of that to y:
y = 3x -2 ⇒ y +2 = 3x
Then we want to undo the multiplication by 3, so we divide by 3:
y +2 = 3x ⇒ (y +2)/3 = x
The solution for x is ...
x = (y +2)/3

In your diagram, each box has the inverse operation of the one in the box above it. The inverse of subtracting 2 is adding 2. The inverse of multiplying by 3 is dividing by 3. The arrows connecting the boxes are intended to show you that these inverse operations occur in the reverse order of the original operations, as we described above. (The small box at bottom center might contain "3x".)

x = 24
what is 7 1/2 divided by 2 1/4 equeal
Answer:
Mixed number: 3 1/3
Improper fraction: 10/3
Step-by-step explanation:
Answer:
3 1/3 or 10 / 3
Step-by-step explanation:
7 1/2 divided by 2 1/4 =
Multiply 7 by 2.
7 x 2 = 14
Add 1 to 14 because of the 1 in 1/2.
14 + 1 = 15
7 1/2 turns into 15 / 2.
Do the same for 2 1/4.
Multiply 2 by 4.
2 x 4 = 8
Add 1 to 8 because of the 1 in 1/4.
8 + 1 = 9
2 1/4 turns into 9 / 4.
15 / 2 divided by 9 / 4
KEEP CHANGE FLIP!!
15 / 2 x 4 / 9
15 x 4 = 60 & 2 x 9 = 18
15 / 2 x 4 / 9 = 60 / 18
Let's simplify 60 / 18 by dividing by the greatest common factor; 6.
60 / 6 = 10 & 18 / 6 = 3
10 / 3 = 3 1/3
Hope this helped!

HELPP! 7th grade math
Answer:
the length would be 3ft and the width would be 2ft
Step-by-step explanation:
this is because the scale is 1cm:4f ft therefore, 12/4=3 and 8/4=2 which is your final answer
Answer:
LENGTH - 3cm / WIDTH - 2cm
Step-by-step explanation:
Well first off, you would use the scale: 1 cm = 4 ft
With 12, you divide by 4. 12 ÷ 4 = 3
With 8, you also divide by 4. 8 ÷ 4 = 2
So, it would be 3 cm long and 2 cm wide.
The fraction a/b is in simplest terms and equal to the following:((2020^3)-1)/((2021^3)+1) . What is a + b?
Consider the expression
[tex]\dfrac{x^3-1}{(x+1)^3+1}[/tex]
Factorize the numerator and denominator a difference/sum of cubes:
[tex]\dfrac{(x-1)(x^2+x+1)}{((x+1)+1)((x+1)^2-(x+1)+1)}[/tex]
Expand the denominator:
[tex]\dfrac{(x-1)(x^2+x+1)}{(x+2)((x^2+2x+1)-(x+1)+1)}=\dfrac{(x-1)(x^2+x+1)}{(x+2)(x^2+x+1)}=\dfrac{x-1}{x+2}[/tex]
since x = 2020, and clearly 2020² + 2020 + 1 ≠ 0, so we can cancel the factor of x ² + x + 1. This leaves us with
[tex]\dfrac{2020^3-1}{2021^3+1} = \dfrac{2020-1}{2020+2} = \dfrac{2019}{2022}=\dfrac{673}{674}=\dfrac ab[/tex]
so that a + b = 673 + 674 = 1347.

I NEED A 100% ACCURATE ANSWER FOR THIS QUESTION ASAP NO LINKS !!!
Answer:
Infinitely many solutions
Step-by-step explanation:
6x+18=2(3x+9)
6x+18=6x+18
Since both sides are equal to each other, then there are infinitely many solutions because no matter what x is, both sides will be equal to each other.
Answer:
infinite many solutions, (C)
Step-by-step explanation:
Once you distribute you get 6x+18 on both sides. Meaning that the answer is this has infinite many solutions.

On a trip, a student drove 42 miles per hour for 3 hours and then drove 26 miles per hour for 5 hours. What is the student’s average rate of speed, in miles per hour, for the whole trip? *
1. 126 MPH
2. 32 MPH
3. 130 MPH
4. 8.5 MPH
Answer:
34 mph
Step-by-step explanation:
Average speed = total distance / total time
Total distance = ( 40 × 2 + 30 × 3 )
= 170 miles
Total time = 5 h
So, avg speed = 170/5 = 34 mph

4/5 is a fraction
4/5 (v−7)=2
Answer:
v = 9.5
Step-by-step explanation:
[tex] \\ \tt \frac{4}{5} (v - 7) = 2[/tex]
[tex] \\ \tt \mapsto \frac{4(v - 7)}{5} = 2[/tex]
[tex] \\ \tt\mapsto \frac{4v - 28}{5} = 2[/tex]
[tex] \\ \tt \mapsto4v - 28 = 2 \times 5[/tex]
[tex] \\ \tt \mapsto4v - 28 = 10[/tex]
[tex] \\ \tt \mapsto4v = 10 + 28[/tex]
[tex] \\ \tt \mapsto \: v = \frac{38}{4} [/tex]
[tex] \\ \tt \mapsto \: v = 9\frac{2}{4} \: or \: 9.5 [/tex]
The sum of 3 times a number and -2, added to 5 times the number
Answer:
3x + (5x -2)
Step-by-step explanation:
X is any number so 3 times a number is 3x. -2 plus 5 times a number is the same as 5 times a number minus 2. And the sum would be 3x + (5x - 2)

I need help creating a table of values for this equation
9514 1404 393
Answer:
see attached
Step-by-step explanation:
I like to let a graphing calculator or spreadsheet do repetitive calculations. It is well worth the few minutes it takes to learn how to enter a formula into any of the available free spreadsheet programs. The Desmos graphing calculator is amazing in its versatility and usefulness.
There are a couple of things that can help make it easier to construct a table of values.
1) recognize the axis of symmetry for this quadratic is ...
x = -b/(2a) = -25/(2(-5)) = 2.5
So, choosing numbers either side of t=2.5 will cut your work in half.
h(2) = h(3)
h(1) = h(4) . . . for example
2) use Horner form to make manual evaluation easier.
h = (-5t +25)t +2 or = (5 -t)(5t) +2

The rectangular screen on a laptop has an area of 375 cm ^ 2 Its width is 10 cm less than its length. What are the dimensions of the screen?
Answer:
lenght = 25 cm
widht = 15 cm
Step-by-step explanation:
Dimensions of the screen
375 = (l - 10) × l
375 = l² - 10l
l² - 10l -375 = 0
(l + 15)(l -25)
l = -15 or l = 25
lenght = 25 cm
widht = 25 - 10
widht = 15 cm

When simplified what is the answers?
Answer:
-1
Step-by-step explanation:
1. To simplify this expression, let's go through the orders of operations:
|2 - 5| - (12 ÷ 4 - 1)^2|-3| - (12 ÷ 4 - 1)^23 - (12 ÷ 4 - 1)^23 - (3 - 1)^23 - (2)^23 - 4-1Therefore, the answer is -1.

Evaluate each function for the given input values. For f (x)=2/3x+ 3, find f (x) when x= 9 and when x=-3
Answer:
Step-by-step explanation:
f(x) = 2/3 x + 3
x = 9
f(9) = 2/3 * 9 + 3 Divide 9 by 3
f(9) = 2 * 3 + 3 Combine 2 * 3
f(9) = 6 + 3 Combine
f(9) = 9 The answer is just a coincidence. The answer for the next one shouldn't be - 3
f(-3) = 2/3 *(-3) + 3 Divide 3 into - 3
f(-3) = 2*(-1) + 3
f(-3) = -2 + 3
f(-3) = 1
How was this done?
You should observe that whatever value you see on the left in the brackets, appears where the x is on the right. This is a very important concept. You should do your best to understand it because algebra is sort of based on it.

What is 1/3 - 1/7 = ?
Answer:
[tex]\frac{4}{21}[/tex]
Step-by-step explanation:
In order to find the answer you need to find the common denominator of the two fractions multiply the fractions to receive that common denominator and then subtract to find your answer.
[tex]\frac{1}{3} -\frac{1}{7}[/tex]
Find the common denominator:
[tex]CD=21[/tex]
[tex]1\times7=7[/tex]
[tex]3\times7=21[/tex]
[tex]=\frac{7}{21}[/tex]
[tex]1\times3=3[/tex]
[tex]7\times3=21[/tex]
[tex]=\frac{3}{21}[/tex]
[tex]\frac{7}{21} -\frac{3}{21}[/tex]
Subtract numerators
[tex]7-3=4[/tex]
[tex]=\frac{4}{21}[/tex]
