Answer:The answer is choice 3
Step-by-step explanation:
Answer:
I think it is 2 hrs... if there are not any extra variables.
Step-by-step explanation:
A.) 7^4x = 10
log base 10 (7^4X) = log base 10 (10)
4x log base 10 (7) = 1
4x (0.8451) = 1
3.3804x = 1
x = 0.2958
b.) ln(2) + ln(4x-1) = 5
ln (2 * 4x-1) = 5
ln (8x-2) = 5
log base (3) (8x-2) = 5
e^5 = 8x-2
e^5+2 = 8x
x = 18.8016
Answer:
C
Step-by-step explanation:
4*5=20 include c, and 4*-2=-8 include d
30%,
1-5=20%
so 50%-20%= 30%
