Answer:
If a number is a multiple of 2, it may NOT be a multiple of 4. An example would be the number 6.
[tex]6\div2=3[/tex], but [tex]6\div4=1.5[/tex].
However, if a number is multiple of 4, it is guaranteed to be a multiple of 2, since 4 itself is a multiple of 2.
Example:
[tex]8\div4=2[/tex]
This is simply
[tex]8\div2\div2=2[/tex].
It is a multiple of 2 twice.

The perimeter of a rectangle is 160 meters. The length is 20 meters greater than the width. Find the dimensions of the rectangle.
Order the numbers from greatest to least based on their absolute value:
|−25|, |0.5|, |−34|, |0.35|
==============================================================
Explanation:
The absolute value of a negative number is the positive version of that number
|-25| = 25
|-34| = 34
The absolute value of a positive number is that exact same number
|0.5| = 0.5
|0.35| = 0.35
Absolute value represents the distance a number is from 0 on the number line. The distance is never negative, which is why |-25| = 25 for instance.
---------------
After simplifying each absolute value, we get this list {25, 0.5, 34, 0.35}
That sorts from greatest to least to get {34, 25, 0.5, 0.35}
This means the answer is |-34|, |-25|, |0.5|, |0.35|
----------------
note: it might help to think of 0.5 as 0.50, so you can see that 0.50 is larger than 0.35
Andrew needs 995 tickets to get the prize he wants at the arcade. He already has 319 tickets and can earn 42 tickets each time he plays an arcade game. How many games will he have to play in order to have enough tickets to win the prize he wants?

Follow the process for establishing a set of equations: Choose a variable to represent one of the unknowns. Express the remaining unknowns in terms of the variable you chose in step 1. Look for a relationship between the unknowns given in the problem. Write an equation. (Look for the other relationship given in the problem.) The tens digit of a number is twice the ones digit. The sum of the digits in the number is 12. What is the number? Include the entire process for establishing a set of equations, the solution, and an explanation of what the solution means in terms of the variables. Complete your work in the space provided.
Answer:
Number = 84
Step-by-step explanation:
Given
Represent Tens with T and Ones digit with U
[tex]T = 2U[/tex]
[tex]T + U = 12[/tex]
Required
Find the number
Substitute 2U for T in the second equation
[tex]2U + U = 12[/tex]
[tex]3U = 12[/tex]
Divide through by 3
[tex]U = 4[/tex]
Substitute 4 for U in the first equation
[tex]T = 2 * 4[/tex]
[tex]T = 8[/tex]
Hence, the number is 84
How do you simplify Radicals?
√180v^4
Here are the steps required for Simplifying Radicals:
Step 1: Find the prime factorization of the number inside the radical. Start by dividing the number by the first prime number 2 and continue dividing by 2 until you get a decimal or remainder. Then divide by 3, 5, 7, etc. until the only numbers left are prime numbers. Also factor any variables inside the radical.
Step 2: Determine the index of the radical. The index tells you how many of a kind you need to put together to be able to move that number or variable from inside the radical to outside the radical. For example, if the index is 2 (a square root), then you need two of a kind to move from inside the radical to outside the radical. If the index is 3 (a cube root), then you need three of a kind to move from inside the radical to outside the radical.
Step 3: Move each group of numbers or variables from inside the radical to outside the radical. If there are nor enough numbers or variables to make a group of two, three, or whatever is needed, then leave those numbers or variables inside the radical. Notice that each group of numbers or variables gets written once when they move outside the radical because they are now one group.
Step 4: Simplify the expressions both inside and outside the radical by multiplying. Multiply all numbers and variables inside the radical together. Multiply all numbers and variables outside the radical together.
Shorter version:
Step 1: Find the prime factorization of the number inside the radical.
Step 2: Determine the index of the radical. In this case, the index is two because it is a square root, which means we need two of a kind.
Step 3: Move each group of numbers or variables from inside the radical to outside the radical. In this case, the pair of 2’s and 3’s moved outside the radical.
Step 4: Simplify the expressions both inside and outside the radical by multiplying.
The area of a square garden is 209 m squared. How long is the diagonal?
Answer:
[tex]\sqrt{418}[/tex]
Step-by-step explanation:
The length of a diagonal of a square is [tex]\sqrt{2}a[/tex], where a is the length of one side.
If the area of a square garden is 209m, we know that the side length must be [tex]\sqrt{209}[/tex]m, since the area of a square is it’s side length squared.
Now we can substitute inside the formula.
[tex]\sqrt{2}\cdot\sqrt{209}[/tex]
When multiplying roots, the multiplication problem can simplify down to whatever is in the roots multilpied by each other.
So, [tex]209\cdot 2 = 418[/tex]
So the length of the diagonal is [tex]\sqrt{418}[/tex] m.

Solve for p in the literal equation 5p + 9r = q.
Answer:
p = q/5 - 9r/5
Step-by-step explanation:
Step 1: Write equation
5p + 9r = q
Step 2: Solve for p
Subtract 9r on both sides: 5p = q - 9r
Divide both sides by 5: p = q/5 - 9r/5

Hey there! I'm happy to help!
We have twice the number.
2n
We want the sum of that and 13. Sum means to add.
2n+13
And this is 75.
Equation: 2n+13=75
We subtract 13 from both sides.
2n=62
We divide both sides by 2.
n=31
Have a wonderful day! :D
An equation is formed of two equal expressions. The value of n is 31.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Given the sum of twice a number and 13 is 75. Therefore, the equation for this situation can be written as,
[tex]2n+13 = 75[/tex]
Solving the above equation for n we will get,
[tex]2n+13 = 75\\\\2n = 75 -13\\\\2n= 62\\\\n = \dfrac{62}{2} \\\\n= 31[/tex]
Hence, the value of n is 31.

If AB = BC, AB = 4x -2, and BC = 3x + 3, find the
length of AB.
Answer:
AB = 18
Step-by-step explanation: AB = BC
4x -2 = 3x + 3... subtract 3x and add 2
1x = 5.. divide both sides by 1 and x= 5
plug x into 4x -2
4(5) -2 = 18
The measure of length AB, If AB = BC, AB = 4x -2, and BC = 3x + 3, then AB is 18.
What is a line segment?A line segment is a straight line with finite length, and thus, have to endpoints(points on either ends).
We have been given that AB = BC, AB = 4x -2, and BC = 3x + 3, then we need to find the length of AB.
Therefore,
AB = BC
Now substitute the given parameters;
AB = BC
4x -2 = 3x + 3
Then subtract 3x both the sides and add 2;
1x = 5
Then divide both sides by 1
x= 5
Now plug x into 4x -2
AB = 4x -2
AB = 4(5) -2 = 18
AB = 18
Hence, The measure of length AB, If AB = BC, AB = 4x -2, and BC = 3x + 3, then AB is 18.

1. Present ages of Asha and Amina are in the ratio 4:5. Eight year from now, the ratio of their
ages will be 5:6. Find their present ages.
Answer:
32 and 40
Step-by-step explanation:
Their ages are in the ratio 4 : 5 = 4x : 5x ( x is a multiplier )
In 8 years their ages will be
4x + 8 and 5x + 8 in the ratio 5 : 6
Expressing this ratio in fractional form
[tex]\frac{4x+8}{5x+8}[/tex] = [tex]\frac{5}{6}[/tex] ( cross- multiply )
5(5x + 8) = 6(4x + 8) ← distribute parenthesis on both sides
25x + 40 = 24x + 48 ( subtract 24x from both sides )
x + 40 = 48 ( subtract 40 from both sides )
x = 8
Thus their present ages are
Asha = 4x = 4(8) = 32
Amina = 5x = 5(8) = 40

A square garden has an area of 1604 square feet. Approximately how long
is each side of the garden?
Answer:
102 sq. ft.
Step-by-step explanation:
In order to find the side lengths, we divide 1604 by 2. Since it's a square, each side is the same length. Area is length times width so we only need two sides.
1604÷2=102
