Well first solve for x
2x + 3 = -19
2x = -22
x = -11
Therefore yes, -11 is a solution for the function.
2n-5=21
add 5 to both sides
2n=26
divide both sides by 2
n=13
I hope I helped! :)
Answer:
There is one solution and that answer is mixed number form 1 5/7 or exact form 12/7
Step-by-step explanation:
Answer:
x = 27
Step-by-step explanation:
∠ CAD and ∠ EDF are corresponding angles and are congruent, so
∠ CAD = 2x
The sum of the 3 angles in Δ ABD = 180°
sum the angles and equate to 180
72 + 2x + 2x = 180
72 + 4x = 180 ( subtract 72 from both sides )
4x = 108 ( divide both sides by 4 )
x = 27
