The value of x in the given system of equation 7+x/3=2x-5 is 7.2.
What are System of equation?
simultaneous equations, system of equations Two or more equations in algebra must be solved jointly (i.e., the solution must satisfy all the equations in the system). The number of equations must match the number of unknowns for a system to have a singular solution.
There are four methods to solving systems of equations: graphing, substitution, elimination and matrices.
Given a System of equation 7+x/3=2x-5
Simplifying this equation
7+x/3=2x-5
=> 2x - x/3 = 12
=> 5x/3 = 12
=> x = 36/5
=> x = 7.2
Therefore, The value of the x for the given Equation is 7.2.

Given 2X + 4Y = 13 and 3X + Y = 2, what is the value of X?
Answer:
x = -1/2
Step-by-step explanation:
2x + 4y = 13
3x + y = 2 (you can multiply this equation by -4 in order to eliminate the y-term)
-4(3x + y = 2) = -12x - 4y = -8
+ 2x + 4y = 13
-10x = 5
x = -5/10 or -1/2
x(-1/2) + 4y = 13
-1 + 4y = 13
4y = 14
y = 14/4 or 7/2 or 3 1/2

Triangle P R Q is shown. The length of P R is 4, the length of R Q is 6, and the length of P Q is 5. Law of cosines: a2 = b2 + c2 – 2bccos(A) Find the measure of AngleQ, the smallest angle in a triangle whose sides have lengths 4, 5, and 6. Round the measure to the nearest whole degree. 34° 41° 51° 56°
Answer:
41°
Step-by-step explanation:
Using cosine rule : since the 3 sides are given
p = 6 ; q = 4 ; r = 5
q² = p² + r² - 2prCosQ
2prCosQ = p² + r² - q²
COS Q = (p² + r² - q²) / 2pr
Cos Q = (6² + 5² - 4²) / 2*6*5
Cos Q = 45 / 60
Cos Q = 0.75
Q = Cos^-1 (0.75)
Q = 41.409622
Q = 41° ( nearest degree)

The sequence follows a times -1 pattern: 6, -6, 6, -6. Write a formula for the (n)th term of the sequence. Your “n” term must start with 1
Answer:
The formula for the nth term of the sequence is:
[tex]a_n=a_1\cdot r^{n-1}[/tex]
Step-by-step explanation:
Given the sequence
6, -6, 6, -6
A geometric sequence has a constant ratio r and is defined by
[tex]a_n=a_1\cdot r^{n-1}[/tex]
Computing the ratios of all the terms of the adjacent terms
[tex]\frac{-6}{6}=-1,\:\quad \frac{6}{-6}=-1,\:\quad \frac{-6}{6}=-1[/tex]
The ratio of all the adjacent terms is the same and equal
so
r = -1
so substituting r = -1 and [tex]a_1=6[/tex] in the geometric sequence
[tex]a_n=a_1\cdot r^{n-1}[/tex]
[tex]a_n=6\left(-1\right)^{n-1}[/tex]
Thus, the formula for the nth term of the sequence is:
[tex]a_n=a_1\cdot r^{n-1}[/tex]

Area is the amount of space that a two dimensional object or figure occupies.
The area of the big rectangle = length * width = 12 * 4 = 48 ft²
Area of hole = length * width = 2 * 2 = 4 ft²
Amount of carpet required = 48 ft² - 4 ft² = 44 ft²

prove that:
A=3x-4 for every x≥2
Answer:
We know that the function IxI is such that:
IxI = x if x ≥ 0
IxI = -x if x < 0.
In this case, we have:
A = I3x - 6I + 2
If we do the same as above, we can write:
A = (3x - 6) + 2 if (3x - 6) ≥ 0
Let's look at the condition in the right, let's isolate the variable:
(3x - 6) ≥ 0
3x ≥ 6
x ≥ 6/3 = 2
Then the condition:
(3x - 6) ≥ 0
is equivalent to:
x ≥ 2
Then we can write:
A = (3x - 6) + 2 if x ≥ 2
If we simplify it further, we get:
A = 3x - 6 + 2 if x ≥ 2
A = 3x - 4 if x ≥ 2
This is what we wanted to prove.

To answer this, we need to understand something
Firstly is that we have dotted lines of the inequality line does not have an equal
to
And also, the solution is directly related to the inequality sign. If it states greater than, solution will be greater than (above the line). If it states less than, solution will be less than (below the line)
So let us take the inequalities one after the other from left to right
1. solid line and below the line
2. dotted lines and above the line
3. solid line and above the line
A young sumo wrestler decided to go on a special high-protein diet to gain weight rapidly. After 11months, he weighed 140 kilograms. He gained weight at a rate of 5.5 , point, 5 kilograms per month. Let yyy represent the sumo wrestler's weight (in kilograms) after xxx months.
Answer:
y = 5.5x + 79.5
Step-by-step explanation:
Given that:
Weight gained after 11 months = 140 kg
Rate of weight gain = 5.5kg per month
Weight in kg after x months = y
Representing the equation in the form:
y = mx + c
m = rate of water gain = slope = 5. 5
.the intercept c, can be obtained thus ;
x = 11 ; y = 140
140 = 5.5(11) + c
140 = 60.5 + c
140 - 60.5 = c
79.5 = c
Hence,
y = 5.5x + 79.5
