Hey there!
-1.3n = 7.8
First, you have to DIVIDE both sides by -1.3
-1.3n / -1.3 = 7.8 / -1.3
Cancel out: -1.3 / -1.3 because it gives you the value of 1
Keep: 7.8 / -1.3 because it gives us the value of n
7.8 ÷ -1.3 = -6
Thus, n = -6 ✅
Good luck on your assignment and enjoy your day!

Answer:
25º celsius
Step-by-step explanation:
The formula for converting fahrenheit to celsius is: Deduct 32, then multiply by 5, then divide by 9
77 - 32 = 45 x 5 = 225/9 = 25º
Answer:
10
Step-by-step explanation:
let the number be n then half the number is 
n, then
n + n = 15
Multiply through by 2 to clear the fraction
2n + n = 30, that is
3n = 30 ( divide both sides by 3 )
n = 10
Thus the number is 10

Given:
A space shuttle can travel at 28968 km/h.
To find:
The distance it can cover in 8 hrs.
Solution:
We have,
Speed of space shuttle = 28968 km/h.
So,
Distance covered by the space shuttle in 1 hour = 28968 km/h.
Distance covered by the space shuttle in 8 hour = (28968 × 8) km
= 231744 km
Therefore, the distance it can cover in 8 hrs is 231744 km.
