Answer: 7.5×10^-4
Step-by-step explanation:
0.00075
Scientific notation means standard form
There are 3 zeros in front of the 7
So take the decimal to the back of 7
You have
7.5
Since you are counting backward, it will be negative
So we have
7.5×10^-4
Answer:
Step-by-step explanation:
8x - 13 = 6x + 11
Subtract 6x from both sides
8x - 6x = 13 + 11
Add 13 to both sides
2x = 24
divide both sides by 2
x = 12
Check solution in original equation;
8(12) - 13 = 6(12) + 11
96 - 13 = 72 + 11
83 = 83
