Please check the explanation.
Step-by-step explanation:
Given the verbal expression
''Thirteen less than twice the sum of a number and six is 47''.
Let us break down the verbal expression into an algebraic equation
- Sum of twice the number and six = 2n+6
- Thirteen less than twice the sum of a number and six = 2n+6-13
And finally
Thirteen less than twice the sum of a number and six is 47:
2n+6-13 = 47
Therefore, the equation is:
Solving the algebraic expression
solving the equation for 'n'


Add 7 to both sides

Simplify

Divide both sides by 2

Simplify

Answer:
the angle of this is 80 all havevtobdo is add all the sides of the angle
F(x)=-3x
f(-5)=-3* (-5)
=15
