-
A.
7 -
B.
6 -
C.
5 -
D.
4
Correct Answer: Option A
Explanation
23x = 325
2 (times x^1 + 3 times x^0 = 3 times 5^1 + 2 times 5^0)
= 2x + 3 = 15 + 2
2x + 3 = 17
2x = 17 – 3
2x = 14
x = (frac{14}{2})
x = 7
23x = 325
2 (times x^1 + 3 times x^0 = 3 times 5^1 + 2 times 5^0)
= 2x + 3 = 15 + 2
2x + 3 = 17
2x = 17 – 3
2x = 14
x = (frac{14}{2})
x = 7
