Use substitution
3x = 2(-6x + 18) + 14
3x = -12x + 36 + 14
3x = -12x + 50
15x = 50, x = 50/15 = 10/3
Solution: x = 10/3
Answer:
$33
Step-by-step explanation:
Since 9 pies is 27 dollars that means you have to divide 27 by 9 to find out what 1 pie costs
1 pie ends cause costing $3
now you multiply the cost for 1 pie and 11 so it comes out to be $33
Answer:
Denote AH as height of triangle ABC, with H lies on BC.
Applying sine theorem:
AH/AC = sin 60
=> AH = AC x sin 60 = 47 x sqrt(3)/2 = 40.7
=> Area of triangle ABC is calculated by:
A = AH x BC x (1/2) = 40.7 x 30 x (1/2) = 610.5 = ~611
=> Option C is correct.
Hope this helps!

Answer:
Step-by-step explanation:
I suspect it is 64 not 65,
9x^2-64y^2
= (3x - 8y)(3x + 8y).
(If it is 65 there are no factors)
