I need help too you not alone in this but I think photo math would help
The power used in each bolt is 125.
1000- the power together
Divided by the 8 - lights together
So you would do 1000 divided by 8 to get the power of an individual light, which is 125. (1000 ➗ 8 = 125.)
You could even check ur answer by 8 x 125 equals 1000
7/10.
convert 2/5 to 4/10 multiplying both by two and add the two numerators. 4 +3 and get 7. That makes 7/10.
