Write the thing spaced out:
4a <u>-5b</u> +6ab <u>-8b</u> -3a
The signs (+,-) are assigned to the numbers it is in front of.
We minus the "like" terms:
4a - 3a = 1a
<u>-5b - 8b = -13b
</u>+6ab = +6ab
Put them all together:
1a - 13b + 6ab
The answer for, "4a - 5b + 6ab - 8b - 3a" = "1a - 13b + 6ab"
Answer:
Amount of crimson velvet left = 3200 - 120 - 1400 = 1680 cm
Step-by-step explanation:
The arts and craft shop has a bolt of crimson velvet of 32 meters long. A customer bought 120 centimetres of the velvet. In the afternoon another customer bought 14 meters. The remaining length of crimson velvet Malik shop possess after the morning and afternoon sales can be calculated below.
The total length of the crimson velvet = 32 meters. Since our answer should be in centimetre we will convert all the units to cm.
total length = 32 m
1 m = 100 cm
32 m = ?
cross multiply
total length in cm = 32 × 100 = 3200 cm
The first customer bought 120 cm
The second customer bought 14 m so let convert again.
1 m = 100 cm
14 m = ?
cross multiply
the second customer length in cm = 14 × 100 = 1400 cm
The amount left in the shop will be as follows
Amount of crimson velvet left = 3200 - 120 - 1400 = 1680 cm
