Okay so first figure out what 2.4 times 10 with the power of negative 3 is.
2.4 times 10 is 24 and 24 to the power of 3 is 13,824
so an addition problem could be 5,986+7,838= 13,824
then you could do for a subtraction problem 23,789- 9,965 = 13,824
I hope this helped you. (;

Answer:
x = 7.5
Step-by-step explanation:
Since we see that sides AD and DC are equal, as well as sides BE and EC, we can use this information to conclude that the value of 2x-7 is equal to double the value of DE.
2x - 7 = 4(2)
2x - 7 = 8
2x - 7 + 7 = 8 + 7
2x = 15
x = 7.5
