100=d+(d-20)
First add 20 to both sides.
120=d+d
Now divide the sides by 2.
D=60
There are 60 democrats.
100=60+(60-20)
100=60+40
there are 60 democrats and 40 republicans
Answer:
A is correct pls give likes and brainliest (I actually checked the work sheet for answer key)
1. 12a²b² + -7a²b² + 9a²b²
= 14a²b² (the terms a²b² are like terms so don't look at them, just add 12 + (-7) + 9.
= 14 (ab)² (you can write like this too because both a & b are squared).
2. y² - (-5y²)
= 6y² (subtract -5 from 1, y² is the like term).
Answer:
1/4 month per book. other answer options: 0.25 or 25%
Step-by-step explanation:
If he is reading 8 books in two months, each number can be divided by 2 to get his number of books read in one month.
8/2 = 4
2/2 = 1
4 books per 1 month is equivalent to a quarter of a month per book. This means after each month, he will have 4 books read. After two months, he will have his 8 read.
