-4 and -5
because to get 16 to 12 you have to subtract 4 but it wants you to add so you put a negative sign infront of it.

and a negative multiply by a negative equals a positive so -3×-5=15

Answer:

1.x=-4

2. x=-5

Step-by-step explanation:

16+x=12

Subtract 16 from each side

16+x-16 = 12-16

x = -4


-3x=15

Divide each side by -3

-3x/-3 = 15/-3

x = -5

pishuonlain [190]

Answer:

Volume of room will be left after Michael stores the boxes 426 feet cube

Step-by-step explanation:

It is given that

Michael is putting 12 boxes in a storage shed.

Each box is in the shape of a rectangular prism with dimensions 1.5 feet by 1.5 feet by 2 feet.  

If the storage shed has dimensions 6 feet by 10 feet by 8 feet,

<u>To find the volume of one box </u>

Volume = 1.5 x 1.5 x 2= 4.5 feet cube

Volume of 12 such box = 4.5 x 12 =54 feet cube

<u>To find the volume of shed </u>

Volume of Shed = 6 x 10 x 8 =480

<u> To find remaining portion of shed</u>

Volume of room will be left after Michael stores the boxes      =volume of shed - volume of box

 =480 - 54 = 426 feet cube
