3x-2(x+3)=4x-9-x is the question
Answers
Answer:
[tex]\large\boxed{x = 7}[/tex]
Step-by-step explanation:
3x - 2(x + 3) = 4x - 9 - x
Start by multiplying 2 by the values in the parenthesis
3x - 2x + 6 = 4x - 9 - x
Subtract 3x - 2x and 4x - x
x + 5 = 3x - 9
Add 9 to both sides of the equation
x + 14 = 3x
Subtract x from both sides of the equation
14 = 2x
Divide both sides of the equation by 2
[tex]\large\boxed{x = 7}[/tex]

∠A and ∠B are vertical angles. If m∠A=(3x-30)° and m∠B=(2x-9)°,then find the value of x.
Answers
Answer:
x = 21
Step-by-step explanation:
Vertical angles are congruent, thus
∠ A = ∠ B , substitute values
3x - 30 = 2x - 9 ( subtract 2x from both sides )
x - 30 = - 9 ( add 30 to both sides )
x = 21
Hello there! :)
[tex]\huge\boxed{x = 21}[/tex]
Vertical angles are congruent, therefore:
∠A ≅ ∠B
3x - 30 = 2x - 9
Subtract 2x from both sides:
3x - 2x - 30 = 2x - 2x - 9
x - 30 = -9
Add 30 to both sides:
x - 30 + 30 = -9 + 30
x = 21.

You can re-write the fraction as:

But we know 3x-y=12, so answer A
Let me know if you want workings out on paper :)
Answer:
option A
Step-by-step explanation:
[tex]3x-y=12\\ =>3x = 12+y\\=>x=\frac{y+12}{3}[/tex]
Putting the value of x in [tex]\frac{8^{x} }{2^{y} }[/tex] gives :-
