Answer:
$2,185
Step-by-step explanation:
Multiply the amount spent by the tax rate.
23,000 x 9.5% = $2,185
The common factor would be 3 because 3 is the highest multiple of 15 and 9
Answer:
9
Step-by-step explanation:
the answer is 9 because 18 $÷2 = 9
Arc tan ( 1/√3 ) = arc tan ( √3/3 ) = 30°
180° = π ( in radians )
30° = 180°/6 = π/6
3x + 4y = 31
2x - 4y = -6
*The +4 and -4 in the center of the equation cancel out because 4-4 = 0*
3x = 31
2x = -6
------------
*add like terms*
3x + 2x = 5x
31 - 6 = 25
So now you should have this written on your paper ... > 5x = 25
*Divide by 5 on each side*
5x = 25

5 5
x = 5
