Answer:
0.05?
Step-by-step explanation:
0.2 are taken by oarents
3/4 = 0.75 were taken by parents
0.20 + 0.75 = 0.95
1.00 - 0.95 = 0.05
There are 12 inches in 1 foot, so I would assume that one inch would be 12 times shorter than one foot.
1st you combine like terms so subtract 7y and 3y and you get 4y. So this is the final answer: 4y+4b.
