You know that e= mc^2. In order to find the Value of mc, you have to take squareroot on both sides. So,
squareroot of e= mc
Answer:
20
Step-by-step explanation:
We can set up a percentage proportion to find the value of x.

Now we cross multiply:

Answer:
46x-22
Step-by-step explanation:
5(12x-3)-7(2x+1)
60x-15-14x-7
60x-14x-15-7
46x-15-7
46x-22
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
