Answer:

8b + 5

Step-by-step explanation:

By consulting the table below, you will find how I got 8b + 8, and then

Since 8 and -3 are like terms, I put them together

8 - 3 = 5

So in the simplest form the equation is

8b + 5

Answer:

Step-by-step explanation:

Devin is making a candle by pouring melted wax into a mold in the shape of a square pyramid.

Each side of the base of the pyramid is 9 cm and the height of the pyramid is 10 cm (as shown in figure below)

also, To get the wax for the candle, Devin melts cubes of wax that are each 4 cm by 4 cm by 4 cm

We have to find the number of wax cubes will Devin need in order to make the candle.

Consider Wax cubes of dimension 4 cm by 4 cm by 4 cm

Volume of cube =  (side)³

Thus, Volume of one wax cube is given by = (side)³

Volume of one wax cube  = (4)³= 64 cm³

Now we find the volume of square pyramid.

Volume of square pyramid =

Thus,Volume of given square base with base side 9 cm and height 10 cm is

Area of square = (side)²

Volume of square pyramid =

Volume of square pyramid =

Volume of square pyramid =

thus, the volume of square pyramid is 270 cm³

(approx)

Thus, the number of wax cubes required is 4.21. Rounding it off to the nearest whole number, we will get 5.

Thus,the number of wax cubes required is 5.

Inner

Last

3x*3x=9x^2

3x*-8=-24x

6*3x=18x

6*-8=-48

9x^2-24x+18x-48

9x^2-6x-48

Answer:

x= 200

Step-by-step explanation:

The given equation is:

1/5 x - 2/3 y = 30

The value of y is 15

Put the value of y in the given equation:

1/5 x - 2/3(15) = 30

1/5 x- 10 = 30

Take the L.C.M of the denominator

x-50/5 = 30

Move the denominator to the R.H.S

x-50 = 30*5

x-50 = 150

Combine the like terms

x= 150+50

x = 200

The value of x is 200...
