so

4x + 7 = 5(x - 4)

4x + 7 = 5x - 20

5x - 4x = 7 + 20

x = 27

7,013 ×10⁷ as a whole number​
Charra [1.4K]

Answer:

70130000000

Step-by-step explanation:

(Assuming that that 7013 is supposed to be 7013 not 7.013), We will move the decimal place to the right 7 times, since it is 10 to the power of 7. Since the decimal place is at the end of the number, we have to add 7 zeros. This becomes 70130000000.
