Answer:

x = 9

Step-by-step explanation:

1/2(6x - 10) + 10 = 5x - 13

3x - 5 + 10 = 5x - 13

3x + 5 = 5x - 13

3x + 18 = 5x

18 = 2x

(1.2 x 10-4) + (2.4 x 10-3)
ryzh [129]

Answer:

29

Step-by-step explanation:

(1.2 x 10-4) + (2.4 x 10-3)

Simplify

1.2 x 10- 4 = 8

2.4 x 10- 3 = 21

Add both sums to get 29!

SCIENTIFIC NOTATION

2.9 x 10 to the 1st power

Move the decimal over to make a number less than ten, so that makes 2.9 and 10 to the 1st because you moved the decimal once! Hope this is better
