Answer:

x=-6, y=0

Step-by-step explanation:

Use the 3x-9y=-18 equation and add 9y to both sides to have 3x on its own on the left side. Then, divide by 3 on both sides. Then you'll have x=-6+3y. Plus this back into the 5x+4y=-30 equation and you'll get 5(-6+3y)+4y=-30. Use the distributive property and you'll get -30+15y+4y=-30. Simplify and get -30+19y=-30, then add 30 to both sides and you'll get 19y=0. Divide by 19 on both sides and you'll get y=0. Now that we know y=0, plug that back into the 5x+4y=-30 equation, and you'll get 5x+4(0)=-30. Simplify and you'll get 5x=-30. Divide by 5 on both sides and you'll get x=-6.

Malik's arts and crafts shop has a bolt of crimson velvet 32 meters long. A customer came in during the morning and bought 120 c
vladimir2022 [97]

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
