I think it’s 9+2 because it say sum
Distance(Mercury, Sun) = 5.8 x 10^7
distance(Venus, Sun) = 1.1 x 10^8
distance(Venus, Mars) = 1.1 x 10^8 - 5.8 x 10^7
The subtraction is a little easier if you borrow a power of 10 from the 10^8, multiplying 1.1 by 10.

simply subtract 5.8 from 11.0.
This gives us a result of 5.2 x 10^7.
Hope that makes sense!
Step-by-step explanation:
J(x)=-8x+48
J(5)=-8×5+48
J(5)=-40+48
J(5)=8
Question
Solve the equation 5/6x-4=-2
5/6x - 4 = -2
5/6x = 2
x = 2 * 6/5
x = 12/5
-------------------
check
5/6 * 12/5 - 4 = -2
2 - 4 = -2
the answer is good
