If 3x + 2 = 6, what is the value of x?
Answer:
x = [tex]\frac{4}{3}[/tex]
Step-by-step explanation:
Given
3x + 2 = 6 ( subtract 2 from both sides )
3x = 4 ( divide both sides by 3 )
x = [tex]\frac{4}{3}[/tex]
Answer:
[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{x = 1.33}}}}}[/tex]

A dinner check is to be split among 3 people. Greg’s portion of the check is twice Kelly’s. Joe’s portion is $1.50 less than 4 times Kelly’s. If the total bill is $114.00, how much does each person owe?
Answer:
Kelly owes $16.5
Greg owes $33
Joe owes $64.5
Step-by-step explanation:
Let
Kelly's portion = x
Greg's portion = 2x
Joe's portion = 4x - 1.50
Total bill = $114.00
Total bill = Kelly's portion + Greg's portion + Joe's portion
114 = x + 2x + (4x - 1.50)
114 = 3x + 4x - 1.50
114 = 7x - 1.50
Add 1.50 to both sides
114 + 1.50 = 7x - 1.50 + 1.50
115.5 = 7x
Divide both sides by 7
x = 115.5 / 7
= 16.5
x = $16.5
Kelly's portion = x
x = $16.5
Greg's portion = 2x
= 2 × 16.5
= $33
Joe's portion = 4x - 1.50
= 4(16.5) - 1.50
= 66 - 1.50
= $64.5
Therefore,
Kelly owes $16.5
Greg owes $33
Joe owes $64.5
Given h(x) = -x + 1 find h(0)
Answer:
1
Step-by-step explanation:
Just replace 0 instead of x and simplify.
The required value of h(0) is 1.
What is a function?A function is defined as a relation between a set of inputs having one output each. In simple words, a function is a relationship between inputs where each input is related to exactly one output.
Now the given function is,
h(x) = -x + 1
To find the value of h(0), put x= 0 in the given equation
⇒ h(0) = -0+ 1
Since, -0+ 1= 1
∴We obtain,
h(0) = 1
which the required value of h(0).
Hence,the required value of h(0) is 1.

Using the graph below which coordinates locate the reflection of point R over the given line?
Answer:
(-4, 0)
Step-by-step explanation:
You can plot the points and choose the one that looks like it's in the right place for a reflection across the line. The line of reflection will be the perpendicular bisector of the segment between R and its image.
In the attached plot, we see that the third choice (point C) is the desired image of R.

A gumball machine contains 100 gumballs of 5 different colors: 36 red, 15 blue, 24 orange, 12 green, and the rest are white. The machine dispenser randomly selects one gumball. What is the probability that the gumball dispensed is white?
Answer:
13
Brainliest?
Step-by-step explanation:
The probability that the gumball dispensed white would be 87%.
What is the probability?Probability refers to a possibility that deals with the occurrence of random events.
The probability of all the events occurring need to be 1.
It can be express the probability in either fraction form or in percentage. The numerator would be number of all possibilities, while the denominator is the number of all events.
Here the numerator is the number of white gumballs, while the denominator is the number of all gumballs available.
To solve for the number of white gumballs, subtract all the other balls to the total.
Number of white balls = 100 - 36 red - 15 blue - 24 orange - 12 green
Number of white balls = 13
Thus,
Probability of white ball = 87/100= 87%

In order for the data in the table to represent a linear function with a rate of change of +5, what must be the value of a?
Answer:
a=18
Step-by-step explanation:
The value of a or m is 18 in the linear equation, y = 5x - 2.
What is the system of equations?One or many equations having the same number of unknowns that can be solved simultaneously called as simultaneous equation. And simultaneous equation is the system of equation.
Given:
The table represents a linear function.
The data is given in the attached image.
The general equation of the linear function is,
y = ax+b.
Where a is the slope and b is constant.
By using the first and the third points from the table to find the equation of the linear function,
When x = 3 and y = 13,
13 = 3a+b {equation 1}
When x = 5 and y = 23
23 = 5a+b {equation 2}
Solving the system of equation,
we get,
a = 5 and b = -2
So, the equation is,
y = 5x - 2
Now, x = 4
Then y = m = 20 - 2 = 18
Therefore, the value of m is 18.

Answer:
(1, 5)
Step-by-step explanation:
The midpoint of a line segment has coordinates that are the average of the end-point coordinates.
M = (X + Y)/2 = ((-3, 4) +(5, 6))/2 = (-3+5, 4+6)/2 = (2, 10)/2
M = (1, 5)
The midpoint is (1, 5).

What is the opposite of 8.4
Answer:
-8.4
Step-by-step explanation:
Because if you want to find the opposite of a number then you find that same number on the other side on the number line for example, -4.5 you would go on the other side and you would get positive 4.5
Answer:
If you're refering to the additive inverse then it's, -8.4
Step-by-step explanation:
To get an additive inverse or more so an opposite, you simply add the negative to the original for 0.

AC
B is between the points A and C on
Write an equation using the information in
terms of x. Find x, AB, and BC.
AB = 8x + 5
BC = 5x - 9
AC = 74
The equation is given as: 13x - 4 - 74 = 0
The value of x is 6
AB = 53
BC = 21
Given,
B is between points A and C on AC.
AB = 8x + 5
BC = 5x - 9
AC = 74
We need to write an equation using the information in terms of x
We also need to find x, AB, and BC.
If there is a point between two points of a line, the sum of the two lines separated by the point is equal to the line given.
Example:
M______N____________O
Then,
MN + NC = MO
Find the equation that represents AC with point B between A and C.
We have,
A______B___________C
AB = 8x + 5
BC = 5x - 9
AC = 74
Now,
AC = AB + BC
74 = 8x + 5 + 5x - 9
74 = 13x - 4
13x - 4 - 74 = 0
Find x.
74 + 4 = 13x
78 = 13x
x = 78 / 13
x = 6
Find AB
AB = 8x + 5
= 8x6 + 5
= 48 + 5
= 53
Find BC
BC = 5x - 9
= 5x6 - 9
= 30 - 9
= 21
Thus,
The equation is given as: 13x - 4 - 74 = 0
The value of x is 6
AB = 53
BC = 21

8 x 10^4 is how many times as large as 4 x 10^-5
Answer:
2 x 10^9
Step-by-step explanation:
There 8 × 10⁴ would be 10⁹ times as large as 4 × 10⁻⁵ which is determined by the division operation.
What is the division operation?In mathematics, divides left-hand operands into right-hand operands in the division operation. The primary purpose of the division is to generate equal groupings or to determine how many people are in each category after a fair distribution.
For example 4/2 = 2
We have to determine 8 × 10⁴ is how many times as large as 4 × 10⁻⁵
Apply the division operation to get
⇒ 8 × 10⁴ ÷ 4 × 10⁻⁵
⇒ (8 × 10⁴) / (4 × 10⁻⁵)
Reduce the term of the numerator
⇒ ( 10⁴) / (10⁻⁵)
⇒ ( 10⁴) × (10⁵)
⇒ ( 10⁴⁺⁵)
⇒ 10⁹
Hence, there 8 × 10⁴ would be 10⁹ times as large as 4 × 10⁻⁵ which is determined by the division operation.

Perimeter of rectangle = 26
Length is 7 less than 9 times the width.
We have to find the width of rectangle[tex].[/tex]
_________________________________
Let, width of rectangle be x therefore length of rectangle will be (9x - 7)
We know that, perimeter of rectangle is given by
perimeter = 2 (length + width)⇒ perimeter = 2 (l + b)
⇒ 26 = 2 [(9x - 7) + x]
⇒ 13 = x + 9x - 7
⇒ 20 = 10x
⇒ x = 2 (width)
Cheers!Step-by-step explanation:
Let breadth be x
As it is given that, the Length is 7 less than 9 times :
Therefore, Length will be 9x - 7
Perimeter of reactangle = 26
➳ 2 ( Length + Breadth) = 26
➳ 9x - 7 + x = 26/2
➳ 10x = 13 + 7
➳ 10x = 20
➳ x = 2
Therefore,
Breadth = x = 2 Length = 9x - 7 = 9(2) - 7 = 11
