1) online has the lower unit price
27.25 / 5 = 5.45
32.16 / 6 = 5.3583333.... rounded it would be
5.35
2) The cost of 7 pounds would be 103.18
73.70 / 5 = 14.74 (cost of one pound)
14.74 x 7 = 103.18
3) The scarf in October costed more
13.35 / 3 = 4.45 (one scarf)
22.65 / 5 = 4.53
hope this helps
Answer:
yes
Step-by-step explanation:
Answer:
b) -18(2x -3y + 5)
d) 18(-2x + 3y - 5)
e) -2(18x - 27y + 45)
Step-by-step explanation:
a) -9( 4x - 6y - 10) = -36x + 54y + 90 not equal
b) -18(2x - 3y + 5) = -36x + 54y - 90 equal
c) -6(6x + 9y - 15) = -36x - 54y + 90 not equal
d) 18(-2x + 3y - 5) = -36x + 54y - 90 equal
e) -2(18x - 27y + 45) = -36x + 54y - 90 equal
f) 2(-18x + 54y - 90) = -36x + 108y - 180 not equal
