9d - 5 = 4d + 35

9d (-4d) - 5 (+5) = 4d (-4d) + 35 (+5)

5d = 40

5d/5 = 40/5

d = 8

hope this helps

The answer is D = 8 . You have to subtract 4d from one side and what you do to one side you must do to the other. Then you end up with 5d-5=35. You would add 5 to both sides and get 5d=40. then you divide 5 into both sides and you would get 8 :D

27. Write down the co-ordinates of the points where the line y = 4x - 3 cuts the x-axis <br>

Tamiku [17]

Step-by-step explanation:

it is a line, so that is 1 point, where it cuts the x-axis.

in general that means y = 0.

so,

0 = 4x - 3

4x = 3

x = 3/4

the point, where the line cuts the x-axis is

(3/4, 0)

How many blocks with dimensions of One-third times 1 times 1 can fit in a unit cube?

gtnhenbr [62]

Answer: 3

Step-by-step explanation:

Given

The dimension of the small block is

$\dfrac{1}{3}\times 1\times 1$

The Volume of the cube having unit length is

$V=1\times 1\times 1\\V=1\ unit^3$

The number of blocks that can be in the unit cube is the division of the volume of the unit cube and block.

$\Rightarrow \dfrac{1\times 1\times 1}{\dfrac{1}{3}\times 1\times 1}\\\\\Rightarrow \dfrac{3}{1}=3$
