Answer:
a) 26
b) 26/3
Step-by-step explanation:
a) 4 and 1/3 = 13/3
13/3 x 6/1 = 13/1 x 2/1
b) 2 and 3/5 = 13/5, 3 and 1/3 = 10/3
13/5 x 10/3 = 13/1 x 2/3

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.

Answer:
l = 720ft w = 450ft
Step-by-step explanation:
[tex]2340 = 2l + 2w \\ l = w + 270 \\ 2340 = 2(w + 270) + 2w \\ 2340 = 2w + 540 + 2w \\ 1800 = 4w \\ w = 450 \\ \\ l = 450 + 270 \\ l = 720[/tex]

Use point-slope form to write the equation of a line that passes through the point
(-7, 10) with slope -5.
Answer:
y = -5x - 25
Step-by-step explanation:
Substitute into form of y - y1 = m(x - x1): (Take the point (-7,10) for x1 & y1, m would be the slope)
y - 10 = -5(x -(-7))
y - 10 = -5(x + 7)
y - 10 = -5x - 35
y = -5x - 25
Answer:
y= -5x-25
Step-by-step explanation:
Equation of line with points given =
y = mx + b
m = -5 , x = -7 , y = 10 while the intercept, b is not given, so we need to find that...
Therefore, we substitute the value for the given equation
10 = -5*-7 + b
10 = 35 + b
b = 10 - 35
b = -25
Therefore we substitute the value for m and b to the equation of line
y = -5x - 25

Answer:
Well you got 1/4 + 1/12
So we have to have the same denominator in order to solve this
So by finding a common multiple, you would be able to solve this
So in this case is the common multiple.
we already have a 12 so we leave that be.
We need to convert 1/4 to x/12
To Do that we multiplying it by 3
so 3/12 + 1/12

What is the value of K?
Answer:
The one guy is right k equals 43.6
Hope This Helps!!!
The value of k using Vertical angles is 43.6 degree.
Vertical angles are a pair of non-adjacent angles that are formed by the intersection of two lines. When two lines intersect, they create four angles at the intersection point.
Vertical angles are the angles that are opposite to each other and share the same vertex but are not adjacent. They are Congruent.
As, k and 43.6 are Vertical angles.
So, k = 43.6

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.
