Dividing by 2 always produces a number less than the original number
Dividing the number by 2 gives half of the number which is less than the original number.
Given that,
To specify dividing by 2 always produces a number less than the original number.
A number system is described as a technique of composing to represent digits. It is the mathematical inscription for describing the numbers of a given set by using numbers or other characters in a uniform method. It delivers a special presentation of every digit and describes the arithmetic structure.
Dividing the number by 2 gives half of the number which is less than the original number.
Let the number be x,
Dividing the number by 2
Gives, x / 2 = 0.5 * x
Imply,
Dividing the number by 2 gives half of the number which is less than the original number.
Thus, dividing the number by 2 gives half of the number which is less than the original number.

Simplify: (-2x)4 help me with this!
The simplification of the given equation [tex](-2x)^4[/tex] is [tex]16 * x^4[/tex].
Exponents are mathematical notation used to indicate repeated multiplication of a number or expression by itself.
They are written as superscript numbers or symbols placed to the right and slightly above the base number or expression.
To simplify (-2x)^4, you can apply the power rule for exponents.
(-2x)^4 can be expanded as follows:
(-2x)^4 = (-2)^4 * x^4
Now, evaluate the exponent of the base -2 and x:
(-2)^4 = 16
Thus, the simplified expression is: [tex](-2x)^4 = 16 * x^4[/tex]

Kaiwan sold 40 tickets for Young Baby Durk NBA for the Howard Homecoming concert. He sold general admission tickets for twenty dollars each and VIP tickets for thirty dollars each. He collected eight hundred and eighty dollars. How many of each kind of ticket did Kaiwan sell?
Answer:
number of general admission tickets sold = 32
Number of VIP tickets sold = 8
Step-by-step explanation:
Total Number of tickets = 40
Cost of general admission tickets = $20
Cost of VIP tickets = $30
Total revenue = $880
Let
x = number of general admission tickets sold
y = number of VIP tickets sold
The equations are:
x + y = 40 (1)
20x + 30y = 880 (2)
From (1)
x = 40 - y
Substitute x = 40 - y into (2)
20x + 30y = 880
20(40 - y) + 30y = 880
800 - 20y + 30y = 880
10y = 880 - 800
10y = 80
y = 80 / 10
= 8
y = 8
Substitute y = 8 into (1)
x + y = 40
x + 8 = 40
x = 40 - 8
= 32
x = 32
number of general admission tickets sold = 32
Number of VIP tickets sold = 8
PLS HELP!! Lin ran 2 3/4 miles in 2/5 of an hour, Noah ran 8 2/3 miles in 4/3 of an hour, How long would it take Lin and Noah to run 1 mile at that rate? PLS ANSWER!!
Answer:
Lin will run 1 mile in 8/55 of an hour
Noah will run 1 mile in 2/13 of an hour
Step-by-step explanation:
Here;
Lin ran 2 3/4 miles in 2/5 of an hour
he will run 1 mile in x hour
x * 2 3/4 = 2/5 * 1
2 3/4 = 11/4
x * 11/4 = 2/5
x = 2/5 * 4/11
x = 8/55 hour
For Noah
8 2/3 miles in 4/3 of an hour
1 miles in y hours
y * 8 2/3 = 4/3 * 1
y * 26/3 = 4/3
y = 4/3 * 3/26
y = 4/26 = 2/13
He will run 1 mile in 2/13 hours

Answer:
AnswersMathsGCSEArticle
What are the values of x and y?
a) 3x + 5y = 26
b) 2x + 2y = 12
Step One: We need to find a way to equate either the x terms of the y terms in each equation. Multiply equation a) by 2 and equation b) by 3 to form the following equations.
a) 6x + 10y = 52
b) 6x + 6y = 36
Step Two: Take equation b) from equation a) to eliminate the x component.
a) 6x + 10y = 52
- b) 6x + 6y = 36
0x + 4y = 16
y = 4
Step Three: substitute the value of y into either equation to find the value of x.
b) 2x + 2y = 12
2x + (2x4) =12
2x + 8 = 12
2x = 4
x = 2
x=2 y=4

What is the value of x in the y = 2/3x + 5 when y=7?
Answer:
x = 3
Step-by-step explanation:
y = 2/3 x + 5; y = 7
7 = (2/3)x + 5
2 = (2/3)x
x = 2 * 3/2
x = 3
Answer:
x=3
Step-by-step explanation:
To start all you need to do is replace [tex]y[/tex] with 7 to get [tex]7=\frac{2}{3}x+5[/tex]
Then, you need to isolate x on the right side of the equation, starting with subtracting 5 on both sides to get [tex]2=\frac{2}{3}x[/tex]
Finally, you divide both sides by [tex]\frac{2}{3}[/tex]. You divide fractions by multiplying the reciprocal like so [tex]\frac{2}{1} *\frac{3}{2} =x[/tex] to get [tex]\frac{6}{2} =x[/tex]. This means that x=3
I need help finding the slope, The y-intercept, and the equation??
Answer:
y intercept is (0, 1)
slope is 3
equation is y = 3x +1
Step-by-step explanation:
You find the y intercept when x equals 0 and you can see that on the table that is 1.
You find slope by y2-y1 divided by x2-x1. if you pick (0,1) and (1,4) it is 4-1/1-0 which equals 3.
Therefore the equation is y = 3x + 1 in slope intercept form because the slope is 3 and y int is 1.

Step-by-step explanation:
-5x - (-7 - 4x) = -2(3x - 4)
-5x + 7+ 4x = -6x + 8
-x + 7= -6x + 8
5x = 8 - 7
5x = 1
x = 1/5
An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
The value of x that makes the equation 3/5x - 0.5 = 19 true is 32.5.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x = 4 is an equation.
3x = 6 + 5 is an equation.
We have,
3/5x - 0.5 = 19
Add 0.5 on both sides.
3/5x = 19 + 0.5
3/5x = 19.5
Multiply 5/3 on both sides.
x = 19.5 x 5/3
x = 32.5

Lowest temps, Ontario, CA, April 2020 Date Low temperature 4/4/20 −1.8 °C 4/12/20 0.6 °C 4/18/20 −2.8 °C 4/23/20 (missing) 4/28/20 −0.2 °C The table shows the lowest temperatures recorded on five days in April 2020, but the value for 4/23/20 has been lost. If X is the lost value, and if we know that X was the middle value of the five days, which choice could be the value of X? A) −1.9 °C B) −0.9 °C C) −0.1 °C D) 0.4 °C
Answer: D
Step-by-step explanation:
If you notice there is a pattern going on here the first temp recorded is negetive then the next is a normal temp then the next is negetive so it would be reasonable to think that the next temp would be normal and all the other options are negetive exept for one which is D so the answer is D.
