Y=4x+4 -8x+3y=5 With work

1 answer:

3 0

Y = 4x + 4
-8x + 3y = 5

-8x + 3(4x + 4) = 5
-8x + 12x + 12 = 5
-8x + 12x = 5 - 12
4x = -7
x = -7/4

y = 4x + 4
y = 4(-7/4) + 4
y = -7 + 4
y = -3

solution is (-7/4,-3)

irakobra [83]

Answer:

27 small cubes

Step-by-step explanation:

Given that,

The volume of the large cube is $7.506\times 10^5\ mm^2$

The volume of small cube is $2.78\times 10^4\ mm^2$

We need to find how many small cubes make up the large cube. Let there are n small cubes. So, it can be calculated as follows :

$n=\dfrac{7.506\times 10^5}{2.78\times 10^4}\\\\n=27$

So, there are 27 small cubes that make up of the large cube.
