1) Given equation: x/5 + 9 = 11
2) Subtract from both sides of the equation 9 (use Subtraction Property of Equality):
x/5+9-9=11-9,
x/5=2.
3) Unknown variable is dividend, 5 is divisor and 2 is quotient. To find unknown dividend you should find the product of divisor and quotient or in another words use the Multiplication Property of Equality:
x=5·2,
x=10.
These three consecutive steps show you that correct choice is B.
Answer: correct choice is B.
Cos60 = BC / AB
Cos60 = a/12
answer is D. last one
Cos60 = a/12
<em>Use the Quadratic Formula </em>
x = -4 + 2 √11i/6, -4 - 2√11i/6
<em>Simplify solutions </em>
x = - 2 - √11i/3, - 2 + √11i/3
If it is a straight line.
I believe one answer could be (4x4)=16-10=6+12=18+10=28-4=24?
