1. - 3x-8=10 solve for x

2. (2.3*10^-3) (3*10^8) give answer in scientific notation

1. - 3x-8=10

-3x = 18

18 divided by - 3 is - 6

Answer is - 6 for the first one

2. 300000000 times. 0023 is

690000

So answer for 2 is 6.9 * 10^5

1. X=-62. 690000

Step-by-step explanation:

1. - 3x-8=10

Isolate x on one side of the equation.

-3x-8+8=10+8

Add.

-3x=18

Divide by - 3 from both sides.

-3x/-3=18/-3

Solve.

18/-3=-6

X=-6

X=-6, which is our answer.

2. (2.3*10^-3) (3*10^8)

(2.3*10^-3) (3*10^8) = 690000

690000, which is our answer.
