Answer:

x = 3, y=0

Step-by-step explanation:

2x + y =6

y = x-3

Substitute the second equation into the first

2x +x-3 =6

Combine like terms

3x-3 =6

Add 3 to each side

3x-3+3 = 6+3

3x= 9

Divide each side by 3

3x/3 = 9/3

x =3

Now we need to find y

y = x-3

y = 3-3=0

y=0

Write a ratio, in the simplest form and a percent for the shaded area (there's a 5x4 box and 6 cubes are shaded)

Alexxandr [17]

Answer:

$\%Percent = 30 \%$

Step-by-step explanation:

Given

$Shaded = 6\ cubes$

$Box = 5\ x\ 4$

Required

Determine the percentage of the shaded cubes

First, we calculate the number of boxes:

$Box = 5\ x\ 4$

Express as multiplication

$Box = 5\ *\ 4$

$Box = 20$

This implies that there are 20 cubes in the box.

The percentage of the shaded cubes is:

$\%Percent = \frac{Shaded}{Box} * 100\%$

$\%Percent = \frac{6}{20} * 100\%$

$\%Percent = \frac{6* 100}{20} \%$

$\%Percent = \frac{600}{20} \%$

$\%Percent = 30 \%$

<em>30% were shaded</em>
