Answer:
x = 3
Step-by-step explanation:
6x - 4 = 2x + 8
6x - 2x = 8 + 4
4x = 12
x = 12/4
x = 3
20 * (31/100) = 21*0.31=6.51
20.00-6.51=13.49

Answer:
The easiest way is to determine what number times 9 equals 15.
9x = 15
x = 15 / 9 = 5/3
The original number is 4 + 5/3 = 5 (2/3)
Then we look at the problem again,
5 and (2/3) minus 4 = 5/3 and
5/3 * 9 = 45/3 = 9
Step-by-step explanation:
Answer:
x = 25/9 or 2.777777778
Step-by-step explanation:
4(2-x) = 5x - 17
8 - 4x = 5x - 17
<u> +4x +4x</u>
8 = 9x - 17
<u>+17 +17</u>
25 = 9x
25/9 = x
x = 2.777777778 or 25/9
