What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
We have,
Two numbers:
The difference between the numbers is 1200.
The total of the two numbers = 6484.
Let the numbers be M and N.
Now,
M - N = 1200 ____(1)
M + N = 6484 _____(2)
From (1) and (2) we get,
M = 1200 + N ____(3)
Putting (3) in (2) we get,
1200 + N + N = 6484
1200+ 2N = 6484
2N = 6484 - 1200
2N = 5284
N = 5284/2
N = 2642 putting in (3) we get,
M = 1200 + N
M = 1200 + 2642
M = 3842
Thus the two numbers are 3842 and 2642.

*5) Mr. Harris worked 40 hours this week. He also got a bonus of $180. He
made a total of $780. Write and Solve an equation that can be used to
determine how much Mr. Harris earns per hour?
(Show All Work)
Equation: —————/
Answer:
780 = 180 + 40x
Step-by-step explanation:
first we need to isolate the variable
780-180 = 180-180 + 40x
600 = 40x
600/40 = 40x/40
15=x
so the unit rate or rate per hour Mr. Harris earns is $15 per hour

How do i find the middle top number of a 2x2 matrix?
Answer:
Step-by-step explanation:
the awnser is 04
So if we don't unnecessarily confuse ourselves by taking bases, a 2x2 matrix will always have rank 2 unless one row or column is a scalar multiple of the other*, in which case it will have rank 1. (and also it'll have rank 1 if you have a row or column of zeroes, and rank 0 if it's the zero matrix).

a. The solution of the equation x + 2 = √3x + 10 is x = -3 or x =2.
b. Extraneous solution is x= -3.
c. Extraneous solution does not satisfy original equation.
What is equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign. In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal.
As given in the question,
Given equation :
x + 2 = √3x + 10
a. Squaring both the sides
( x + 2 )² = ( √3x + 10 )²
⇒ x² + 4x + 4 = 3x + 10
⇒ x² + x - 6 =0
⇒ x² + 3x -2x -6 =0
⇒ ( x+ 3) ( x -2) =0
⇒ x= -3 or x = 2
b. Extraneous solution:
x = -3
-3 + 2 = √3(-3)+ 10
⇒ -1 ≠ 1 extraneous solution.
x= 2
2+ 2 =√3(2) +10
⇒4 = 4 not extraneous.
c. Extraneous solution does not satisfy original equation
Therefore, the solution of the equation is x = -3 or x=2and its extraneous solution is x =-3. Extraneous solution does not satisfy original equation.

Find the circumference of a circle 2.1 cm
Answer:
C≈13.19 cm
Step-by-step explanation:
The circumference of a circle equation is C=2πr. Use the circumference of a circle equation and substitute the radius for 2.1. Then, you can calculate 2·π·2.1. The answer to the circumference of a circle is about 13.1946. Finally, you round to the nearsest hundredths place, so the answer is about 13.19 cm.
Work
C=2πr
C= 2·π·2.1
C≈13.1946≈13.19
