6x+1(3x-12)=6
6x+3x-12=6
9x-12=6
+12= 18/9 x=2
Y=6-12
Y=-6 (2,-6
Lets turn E into x and F into y.
We already know that x is 0.8. And if y/x = 0.6, we have to figure that out.
y/x = 0.6
y/0.8 = 0.6
Multiply by 8 to get y = 0.48.
So we have to find P(xy)
So if we know that x = 0.8 and y = 0.48 then all we have to do is multiply 0.48 and 0.8.
0.48 * 0.8 = 0.384
P(E and F) is 0.384.

Answer: y=9
Step-by-step explanation:
Simplifying
7y = 3y + 36
Reorder the terms:
7y = 36 + 3y
Solving
7y = 36 + 3y
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Add '-3y' to each side of the equation.
7y + -3y = 36 + 3y + -3y
Combine like terms: 7y + -3y = 4y
4y = 36 + 3y + -3y
Combine like terms: 3y + -3y = 0
4y = 36 + 0
4y = 36
Divide each side by '4'.
y = 9
Simplifying
y = 9
Expression is: 2.2 × 10⁴ / 8.8 × 10⁹
= 1 × 10⁴ / 4 × 10⁹
= 0.25 × 10⁴⁻⁹
= 0.25 × 10⁻⁵
= 2.5 × 10⁻⁶
In short, Your Answer would be: Option D
Hope this helps!
