1.994 x 10^-23
-0.167 x 10^-23
1.827 x 10^-23
Correct answer is the second one.
You can only solve this by having the same base on each side. So to change 1/27, you can use 3^-3, which is then multiplied through. So the equation is:
4x-5=-3(2x+10)
4x-5=-6x-30
10x=-25
x=-2.5
5 and 1/4 times 3. 1/4 is equal to .25. So, 5.25 x 3 is...
15.75
