Answer:
4x+2y
Step-by-step explanation:
4x-3(x-2y)+1/2x(6x-8y)
remove parentheses
Factor
4x-3x+6y+ 1/2*2(3x - 4y)
Reduce the numbers
4x-3x+6y+(3x - 4y)
remove parentheses
4x-3x+6y+3x - 4y
Answer:
509.85/55= $9.27 old payment per thousand
610.50/55= $11.10 new payment per thousand
(11.10/9.27)-1= 0.197= 19.7% increase
U = sec x ( substitution )
u² + 2 u = 0
u ( u + 2 ) = 0
u = 0, or u = - 2
1/cos x = 0 1/cos x = - 2
(not accepted ) cos x = -1/2
x 1 = 2π/3, x 2 = 4π/3
Less than $3 because 25/7/2
Answer:
Explanation:
Let x be the age of the person who enter the room
(18 + 25 + 18 + 21 + 16 + x)/6 = 25
(77 + x)/6 = 25
77 + x = 25(6)
77 + x = 150
x = 150 - 77
x = 73
