Answer:
x - 6 = 1/3x + 4
x = 15
Hope this helps :)
Hope this helps :)Explanation and Check part below.
Step-by-step explanation:
1. Get the variable on one side by subtracting x.
x - 6 = 1/3x + 4
- 1 x - 1 x
- 6 = - 2/3x + 4
2. Subtract 4 which is the inverse operation of addition.
- 6 = - 2/3x + 4
- 4 - 4
- 10 = - 2/3x
3. Divide by - 2/3 which is the invers eoperation of multiplication.
- 10 = - 2/3x
- 2/3 - 2/3
(Keep,Change,Change - KCC method)
- 10 ÷ - 2/3 = - 10 × - 3/2 = 30/2 = 15
- 10 = - 2/3x
- 2/3 - 2/3
15 = x → x = 15
Check:
15 - 6 = 1/3(15) + 4
9 = 15/3 + 4
9 = 5 + 4
9 = 9

if AC=38 3/4,AB=6x, BC=8x+1/4
what’s the value of x?
Applying the segment addition postulate:
x = 2.75
AB = 6x = 6(2.75) = 16.5 units
BC = 8x + 1/4 = 8(2.75) + 1/4 = 22.25 units.
What is the Segment Addition Postulate?Based on the segment addition postulate, since B lies between points A and C on a line segment, then:
AB + BC = AC
AC = 38 3/4
AB = 6x
BC = 8x + 1/4
Substitute
6x + 8x + 1/4 = 38 3/4 [segment addition postulate]
14x + 1/4 = 155/4
14x = 155/4 - 1/4
14x = (155 - 1)/4
14x = 154/4
14x × 4 = 154
56x = 154
x = 154/56
x = 2.75
AB = 6x = 6(2.75) = 16.5 units
BC = 8x + 1/4 = 8(2.75) + 1/4 = 22.25 units.

Reflection as used in geometry is the representation of an image in the mirror image copy. Reflection is done with respect to a line called line of reflection. Images formed are of equal distant to the line of reflection and the images are usually congruent.
Reflection as represented on a graph is most times in x axis or y axis. This axis shows the location of the line of reflection and it is very important when determining the position of the reflected image.

Congruent segments are LK=MK, LK=7x-10, KN=x+3, MN=9x-11, and KJ=28, the LJ will be-
LJ = 18 + 28 = 46
LJ = 18 + 28 = 46
These are Congruent segments
Let J, K, L, M, N are points on the same line.
MK = MN + (-KN) = MN - KN = 9x - 11 - x - 3 = 8x - 14
As LK = MK and LK = 7x - 10, then
7x - 10 = 8x - 14
8x - 7x = -10 + 14
x = 4
LJ = MK + KJ
MK = LK = 7x - 10 = 7(4) - 10 = 28 - 10 = 18
LJ = 18 + 28 = 46
Congruent segments are segments which have the equal length. ≅ points that lie at the equal line are called collinear.
A theorem is a mathematical assertion that can be proved. The midpoint of a phase is a point that divides the phase into two congruent segments
If three or more points lie on a single straight line, they are said to be collinear. An axis is a term used to describe a line on which points are located, particularly if that line is connected to a triangle or other geometric shape. Since two points determine a line, two points are trivially collinear.

Using a system of equations, it is found that she invested 318.71 into Fund B.
What is a system of equations?A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
For this problem, the variables are given as follows:
Variable x: Amount invested in Fund A.Variable y: Amount invested in Fund B.The amount she invested in Fund A was 3 times as much as the amount she invested in Fund B, hence:
x = 3y.
Fund A returned a 6% profit and Fund B returned a 15% profit, and the total profit was of 1380, hence:
1.06x + 1.15y = 1380.
We have that x = 3y, hence:
1.06(3y) + 1.15y = 1380.
4.33y = 1380
y = 1380/4.33

A Web music store offers two versions of a popular song. The size of the standard version is 2.9 megabytes (MB). The size of the high-quality version is 4.1 MB. Yesterday, there were 1360 downloads of the song, for a total download size of 4532 MB. How many downloads of the high-quality version were there?
The number of standard version download and high-quality download is 870 and 490 respectively.
Number of downloads of the high-quality versionlet
Number of high-quality download = yNumber of standard version = xx + y = 1360
2.9x + 4.1y = 4532
From (1)
x = 1360 - y
Substitute x = 1360 - y into (2)
2.9x + 4.1y = 4532
2.9(1360 - y) + 4.1y = 4532
3944 - 2.9y + 4.1y = 4532
- 2.9y + 4.1y = 4532 - 3944
1.2y = 588
y = 588/1.2
y = 490
Substitute y = 490 into (1)
x + y = 1360
x + 490 = 1360
x = 1360 - 490
x = 870
So therefore, number of standard version download and high-quality download is 870 and 490 respectively.
