1/2 n + 10.5 =3.5 find the value of n
1 answer:
Answer:
n= -14
Step-by-step explanation:
First, convert into a decimal:
as a decimal is 0.5
now the equation is 0.5n+10.5=3.5
Move the constant to the right and change its sign:
0.5n=3.5-10.5
Calculate the difference:
0.5n=3.5-10.5
0.5n= -7
Divide both sides of the equation by 0.5:
0.5n÷0.5= -7÷0.5
n= -14

In box 1, the reason that justifies the statement, m∠BAD = m∠BAC + m∠CAD, is: angle addition postulate.
<h3>What is the Angle Addition Postulate?</h3>The angle addition postulate states that the measure of a larger angle equals the sum of smaller angles that make up the larger angle.
∠BAD comprises of ∠BAC and ∠CAD.
Therefore, based on the angle addition postulate, m∠BAD = m∠BAC + m∠CAD.
The missing reason in box 1 would be: angle addition postulate.
