Answer: (I think it is x=4)
x=4, x=2, or x=10
Step-by-step explanation:
Simplifying
3x + 2(5x) = 26
Remove parenthesis around (5x)
3x + 2 * 5x = 26
Multiply 2 * 5
3x + 10x = 26
Combine like terms: 3x + 10x = 13x
13x = 26
Solving
13x = 26
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Divide each side by '13'.
x = 2
Simplifying
x = 2
----------------------------------------------------------------------------------------
Equation at the end of step 1
3 • (x - 2) - (5x - 26) = 0

:
Pulling out like terms
3.1 Pull out like factors :
20 - 2x = -2 • (x - 10)
Equation at the end of step
3
:
-2 • (x - 10) = 0
STEP
4
:
Equations which are never true
4.1 Solve : -2 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation:
4.2 Solve : x-10 = 0
Add 10 to both sides of the equation :
x = 10
One solution was found :
x = 10
--------------------------------------------------------------------------------
(3x-3*2)+5x=26
(3x-6)+5x=26
3x-6+5x=26
3x+5x-6=26
8x-6=26
(8x-6)+6=26+6
8x-6+6=32
8x=32
8x/8=32/8
x=2^5/2^3
x=2^5-3
x=2^2
x=4
When dividing variables that ave the same base, keep the base and subtract the powers.y^9/y^3 = y^(9 - 3) = y^6
The answer is y^6
Converted to a decimal it’s -0.8
$3.50 + $0.45x = p. The 3.5 dollars is the flat rate and the .45 is for the per mile. Substitute x out for the number of miles and then you get the number of total earnings.
Given:
Height of box = (x-2)
Volume of box =
To find:
The expression for the base area.
Solution:
We know that,
Volume of a box(V) = Base area(B) × Height(h)
On substituting the given values, we get
So, the base area is .
Therefore, the correct option is B.
