What is the volume of the composite solid? 6 m 4 m 3 m 4 m 4 m
Tpy6a [65]

Answer:

Please read explanation

Step-by-step explanation:

A picture would be helpful, but I think the answer might be (6x4x3)+(3x4x4). If your shape is made up of many parts, you should find the volume of each shape then add them up to find the total volume. (To find volume, multiply base x height x width) If you could give a picture, it would be very helpful because I don't really know which numbers I should multiply to find volume. I hope this explanation helps, and please comment if you need to ask me anything.

During the summer, Cecile read twice as many books as Kami. Laura read three times as
Eva8 [605]

Answer:

The equation

c x 2 > k

l x 3 ?> c > k

g = 30 = c + l + k

this equation is the same as...

Cecile read twice as many books as Kami.

Laura read 3 times as many books as Kami, but possibly less than Cecile.

Gigi read 30 books. 30 books is the same as all 3 girls combined.

To find out how many books each girl read, you need to find 3 unequal numbers that add up to 30. These numbers are substituted, only because they can be anything at all, and I want to prevent confusions.

hope this helps!

12x=18-6y in slope intercept form
Sidana [21]

Answer: y = -2x +3

slope intercept form: y = mx +b

divide everything by 6.

2x = 3 - y

isolate y by subtracting 3 from both sides

2x - 3 = -y

divide by negative 1 to get positive y

-2x +3 = y
