Answer:
x = 1/2
Step-by-step explanation:
Answer:
x = 0.5
Step-by-step explanation:
2(4x+2)=4x-12(x-1) (by PEDMAS, we deal with the parentheses first by using the distributive property)
4x(2)+2(2)=4x+ x(-12) -1 (-12)
8x + 4 = 4x - 12x +12 (simplyfy each side)
8x + 4 = - 8x +12 (add 8x to both sides)
8x + 4 + 8x = 12
16x + 4 = 12 (subtract 4 from both sides)
16x = 12 - 4
16x = 8 (divide both sides by 16)
x = 8/16
x = 0.5

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]
Step-by-step explanation:
[tex] \star \sf \: \: {3x + 2 = 6}[/tex]
[tex] \text{ \sf{ Step 1}}[/tex] : Move 2 to right hand side and change it's sign
[tex] \longmapsto{ \sf{3x = 6 - 2}}[/tex]
[tex] \text{ \sf{ Step \: 2 \: }}[/tex] : Subtract 2 from 6
[tex] \longmapsto{ \sf{3x = 4}}[/tex]
[tex] \text{ \sf{ Step \: 3}}[/tex] : Divide both sides by 3

J is the midpoint of CT
T
If:
CJ = 4x - 9 and
JT = 9x – 34
Find CT.
Answer:
Step-by-step explanation:
4x - 9 = 9x - 34
-5x - 9 = -34
-5x = -25
x = 5
4(5) - 9 + 9(5) - 34
20 - 9 + 45 - 34
11 + 11 = 22
The value of CT such that J is the midpoint of CT will be 22.
What is a number system?The number system is a way to represent or express numbers.
A decimal number is a very common number that we use frequently.
Since the decimal number system employs ten digits from 0 to 9, it has a base of 10.
As per the given,
J is the midpoint of CT
CJ = JT
4x - 9 = 9x - 34
-9 + 34 = 9x - 4x
25 = 5x
x = 5
So CT = 2(CJ) = 2(4 x 5 - 9) = 22
Hence "The value of CT such that J is the midpoint of CT will be 22".

The figure below shows how Ali spends his time in a day. Calculate the number of hours Ali
spends on playing.
Answer:
75°C = 5h
Step-by-step explanation :
1. Make sure your mind is fresh and that you understand each step before reading
2. 24 hours is equal to 360°C
3. so now lets break up the hours. We can do this by choosing a simple degree that was given in the diagram. For example "Watching tv".
Tip : when choosing one of the degrees , ( i mean one of the choices like watching tv, playing and sleeping) , try choosing the simplest one , which has a simple number and a multiple of 360.
so now you want to know how many hours is 60 equal to .
= 360 ÷ 60 = 60 (this is to make sure the number is a multiple and will not be a decimal )
= 24 ÷ 6 = 4
this means Ali spend 4 hours watching tv
and by doubling that you get 60°C = 4h
the amount of time he slept 120°C = 8h
and you keep playing with the numbers like that
so for playing
60°C = 4h
divide by 4 15°C = 1h
× by 5 75°C = 5h
this means ali spends 5h playing , 8h sleeping, 4h watching tv and 7 h studding

There are 9 boys and 6 girls in a hall, each holding coins in their hand. The mean number of coins for the children is 18 The mean number of coins for the boys is 14 Work out the mean number of coins for the girls.
Answer:
24
Step-by-step explanation:
Average = total number of coins / number of students
If the mean number of coins with boys is 14, the total number of coins held by boys = 14 x 9 = 126
The total number of coins held by the students = total number of children x average number of coins held by the children
15 x 18 = 270
The total number of coins held by girls = 270 - 126 =144
The mean number of coins for the girls = 144 / 6 = 24

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%

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
