Answer:
12
Step-by-step explanation:
divided 16 by 4 which is 4. then multiply 2 by 6, which is 12. then multiply 4 by 12. Remember to always do ( ) first. 4 by 12 is 48. Then do 48 divided by 6 which is 8. then add 8+4 which is 12.
The right step followed in the system to get he equations is (D). To get the system B. The second equation in system A was replaced by the sum of that equation and the first equation multiplied by 6. The solution to system B will be the same as the solution of system A.
<h3>Meaning of Simultaneous Equation.</h3>
A simultaneous equation can be defined as an equation that possesses two unknowns and one constant.
The solution to the problem can only be gotten by solving it side by side with another equation of the same format.
In conclusion, The right step followed in the system to get he equations is (D). To get the system B. The second equation in system A was replaced by the sum of that equation and the first equation multiplied by 6. The solution to system B will be the same as the solution of system A.

The more fuel efficient car is the car that has 28 miles to a gallen.She would be saving 752 dollars.
Use this formula a2 − b2 = (a + b)(a − b)
<span>(x+1)^2-(x-1)^2 in this case, a = x+1, b = x-1</span>
<span>= [(x+1) + (x-1)] * [(x+1) – (x-1)]</span>
=(x +1 + x – 1) *(x +1 – x +1)
= 2x * 2
<span>=4x</span>
