1. -3x-8=10 solve for x
2. (2.3×10^-3)(3×10^8) give answer in scientific notation

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.
