To find the scale factor you put the first one on top and second on bottom we get 12/16
So the scale factor is .75
If you would like to know what is the solution to the system of equations, you can calculate this using the following steps:<span>
2d + e = 8
d - e - 4 = 0 ... d = e + 4
___________________
</span>
<span>2d + e = 8
</span><span>2 * (e + 4) + e = 8
2e + 8 + e = 8
3e = 0
e = 0
d = e + 4 = 0 + 4 = 4
(d, e) = (4, 0)
The correct result would be: C. The solution is (4, 0).</span>
Algebraic expressions are combinations of variables , numbers, and at least one arithmetic operation. For example, 2x+4y−9 is an algebraic expression. Term: Each expression is made up of terms. A term can be a signed number, a variable, or a constant multiplied by a variable or variables.
from google
I think it would be 4.7A - C
