Answer:
1+1 is 2
Step-by-step explanation:
Well lets do the math
220 x 8 = 1760
1240 x 2 = 2480
2480 + 1760 = 4240
So we need 2 first class and 8 coach.
$5 per hour is the constant rate because 10/2 is 5, 20/4 is 5 etc.
3. -4x - 6
-3(x + 2) - x → ( distribute bracket by - 3)
= - 3x - 6 -x → (collect like terms)
=( - 3x - x) - 6 = - 4x - 6
4. A has the smallest value
A =( 2 - 3 ) = -1
B = 2 × 3 = 6
C = 2 + 3 = 5
D = 
A is negative while the others are all positive.
Thus A is the smallest value expression
