Answer:
0.00007935
Step-by-step explanation:
7.935 x 10 to negative 5 power can be written as:
7.935 x 10^(-5)
A trick to finding 10 to the x power, x is the number of 0's. So 10^5 = 100000

When dividing by tens, move the decimal to the left by the amount of 0's
So our answer is 0.00007935
16x - 4 + 58 + 9x - 6 = 180
25x + 48 = 180
25x = 132
x = 5.28
