Answer:

Step-by-step explanation:
we know that


Let
x ------> new battery life
The equation that represent this situation is

convert to mixed number

For example on -9+6 you would start at -9 and go right 6 times over and what you land on is your answer<span />
6 cups.
2/5 of the mixture would be lemon juice, and 2/5ths of 15 is 6
Answer:
2x-12/2y+3
Step-by-step explanation:
Let's solve for i.
2x−5−3i=7+2yi
Step 1: Add -2iy to both sides.
−3i+2x−5+−2iy=2iy+7+−2iy
−2iy−3i+2x−5=7
Step 2: Add -2x to both sides.
−2iy−3i+2x−5+−2x=7+−2x
−2iy−3i−5=−2x+7
Step 3: Add 5 to both sides.
−2iy−3i−5+5=−2x+7+5
−2iy−3i=−2x+12
Step 4: Factor out variable i.
i(−2y−3)=−2x+12
Step 5: Divide both sides by -2y-3.
i(−2y−3)
−2y−3
=
−2x+12
−2y−3
i=
2x−12
2y+3
Answer:
i=
2x−12
2y+3
