(-8) - 3y= 25
-8-3y= 25
move -8 to the other side
sign changes from -8 to +8
-8+8-3y=25+8
-3y= 33
divide both sides by -3 to get y by itself
and to get +y
-3y/-3= 33/-3
Answer:
y= -11
Answer:
77.44%
49.87%
Step-by-step explanation:
If 12% leaks everyday, on the first day 12% would leak, leaving 100 - 125 = 88% of air
on the second day, 12% of 88% would leak = 0.88 x 0.12 = 0.1056
Air left on the second day = 88% - 10.56% = 77.44%
After a week = (100 - 12%)^7 = 49.87%
Answer:
1/7
Step-by-step explanation:
They traveled 5/7 of the distance on Saturday.
That left 2/7 of the distance as the remaining distance.
They traveled half of 2/7 of the distance on Sunday.
1/2 of 2/7 = 1/2 × 2/7 = 2/14 = 1/7
Answer: 1/7
