What is division?
Division is an arithmetic operation that involves splitting a quantity or number into equal parts. It is the process of finding how many times one quantity is contained within another quantity.
To solve the problem 2/3 ÷ 2, we can use the division operation of arithmetic. However, since this is a simple calculation, there is no need to use a complex model or tool.
Here are the steps to solve the problem:
Divide 2 by 3:
2 ÷ 3 = 0.666666667 (rounded to nine decimal places)
Divide the result from step 1 by 2:
0.666666667 ÷ 2 = 0.3333333335 (rounded to ten decimal places)

Ivan must choose a number between 55 and 101 that is a multiple of 4, 5, and 8. Write all the numbers that he could choose. If there is more than one number, separate them with commas.
Solution:
1. Since the numbers must be divisible by 2 even numbers, all odd numbers are ruled out because odd numbers are not divisible with even numbers.
In this case, the numbers that are possible are:
56, 58, 60, 62, 64, 66, 68, 70, 72, 74, 76, 78, 80, 82, 84, 86, 88, 90, 92, 94, 96, 98, 1002. Since the numbers must be divisible by 5, it rules out a few more numbers.
In this case, the remaining numbers are:
60, 70, 80, 90, 100We can clearly tell that the only number that is divisible by 8, 5, and 4 is 80.
Thus, 80 is the number.

Explain how you would go about graphing this equation? What would be your first step and how would you go from there? Y=4x+6 *
Step-by-step explanation:
First I would look at the y intercept. In a linear equation, y = mx + b, b is the y-intercept and m is the slope. This means that (0,6) is a point on the line since at a y-intercept, the x value is 0. First you should plot this point.
Next, the slope is 4, meaning that for every 1 unit to the right, the line rises 4 units. You can count 1 to the right and 4 up from the y-intercept, which gives you (1,10), a second point on the line. After this, you can connect the two points and there you go, you have a graph!

These two triangles are congruent triangles. This means that the side measurements can be found through a single multiplicative number.
All you have to do is divide 49 by 23 and get 2.130434783. You need that number to be specific
Next you want to multiply that number by the side length that corresponds to the length you are trying to find. In this case that is 7.
7 x 2.130434783=14.9

A phone company offers two monthly plans. Plan A costs $20 plus an additional $0.11 for each minute of calls. Plan B costs $14 plus an additional $0.13 for each minute of calls.
For what amount of calling do the two plans cost the same? ____Answer
What is the cost when the two plans cost the same?
$_____answer
Answer:
a. 300 minutes.
b. $53
explanation:
make equations from given information.
consider each minute as "n"equation 1 from plan A :
20 + 0.11(n)
equation 2 from plan B :
14 + 0.13(n)
Solve them simultaneously,
14 + 0.13(n) = 20 + 0.11(n)
0.13(n) - 0.11(n) = 20 - 14
0.02(n) = 6
n = 300
insert n = 300 in any of the equation, to find cost.
14 + 0.13(n)
14 + 0.13(300)
$53

Bridgette has 25 pairs of black socks, 15 pairs of white socks, and 20 pairs of colorful socks. What is the ratio of colorful socks to total socks?
help?!
could you please explain to?!
Answer:
Step-by-step explanation:
So the total # of socks is 25 + 15+ 20, which equals 60.
theres ONLY 20 socks that are colorful, meaning that 20/60 are coloful.
20/60 simplified is 2/6, simply that even further its 1/3, 1/3 is a ration within itself. itll be 1:3
Answer:
1:3 (20:60)
Step-by-step explanation:
So the ratio of colorful socks to total socks is 20:60
This is how:
First write the number of colorful socks which is 20.
From the calculate the total number of socks( 20 + 25 + 15 = 60) which is 60.
Then put a colon and write 60
You need to write the number of colorful socks because that is what was mentioned first then the total number of socks because it was mentioned after the number of colorful socks.
So you can reduce 20:60 to its lowest term.
You write 20: 60 as a fraction [tex]\frac{20}{60}[/tex]
Then reduce [tex]\frac{20}{60}[/tex] to its lowest term which is [tex]\frac{1}{3}[/tex].
Then write [tex]\frac{1}{3}[/tex] as a ratio which is 1:3

What is the value of x in the equation 8x – 2y = 48, when y = 4?.
Step-by-step explanation:
Substitute the value of y into the equation;
[tex]8x-2(4)=48[/tex]
Find the value of x.
Multiply;
[tex]8x-8=48[/tex]
Add 8 to each side;
[tex]8x=56[/tex]
Divide each side by 8;
[tex]x=7[/tex]
Answer:
x = 7
Step-by-step explanation:
Given:
y = 4Step-1: Substitute the y-variable in the equation (8x – 2y = 48)
⇒ 8x - 2y = 48⇒ 8x - 2(4) = 48Step-2: Simplify the L.H.S
⇒ 8x - 2(4) = 48⇒ 8x - 8 = 48Step-3: Add 8 both sides
⇒ 8x - 8 = 48⇒ 8x - 8 + 8 = 48 + 8⇒ 8x = 56Step-4: Divide 8 both sides
⇒ 8x = 56⇒ 8x/8 = 56/8⇒ x = 7The volume of a sphere is 36 cubic inches. What is the radius of the sphere?
Answer:
2.05 inches
Step-by-step explanation:
V = 4/3 x πr³
36=4πr³/3
36x3= 4πr³
108= 4πr³
108/4 = πr³
27= πr^3
27/π =r³
r=
[tex] \sqrt[3]{27 \div \pi} [/tex]
r= 2.048in
round off to 2.05in
PROOF
V = 4÷3 x πr³
V= 4/3 x π(2.05)³
V=4/3 x π8.6
V=4×π×8.6/3
V=108/3
V=36in³
Therefore: radius= 2.05 inches
-4m + 2n = 6
-4m + n = 8
solve for and x and y steps
I am doing this problem assuming that you mean to solve for m and n as x and y do not exist in this system of equations.
-4m+2n=6
-4m+n=8
We can see that the coefficient of x for both equations are -4; therefore, elimination with subtraction is possible.
First equation - second equation
n=-2
Then substitude back in to solve for m
-4m+(-2)=8
4m=10
m=5/2
Therefore the answer is
n= - 2
m= 5/2
