Well, if rounded by thounsandths, it would be 40,000-30,000. This would equal 10,000.
However, if it was rounded by hundredths, it would be 36,500-32,800. This would equal 3,700.
2x -7=13 is an equation because it has an equal sign.
Answer:
4E
Step-by-step explanation:
Step-by-step explanation:
elimination of x:
-6x +5y = 1
6x + 4y = -10
___________+
9y = -9
y = -9/9 = -1
elimination of y:
-24x +20y = 4
30x + 20y = -50
_____________-
-54x = 54
x = 54/-54 = -1
{ -1, -1}
X/6 - 5 = 13
x/6 = 13 + 5
x/6 = 18
x = 18*6
x = 108
Verify:
108/6 - 5 = 13 ?
18 - 5 = 13
13 = 13 (yes)
