Answer:
1) Reflections just change the signs of the coordinates, so (1.5, -2) and (-1 and 1/2, 2) are reflections of each other. Also (1.75, -4) and (-1 and 3/4, 4)
2) From left to right: -1.75, -3/4, 1/4, 0.75, 1 and 1/2.
Remember that each 1/4 = 0.25, so this could help you work out fractions and decimals.
Given 17 books.
Total 56 b<span>ooks.
How many books were in her collection before her teachers donation?
</span>
First lets write an equation:
b = books before
17 + b = 56
Lets solve for b:
17 + b = 56
Inverse Operation:
56 - 17 = b
56 - 17 = 39
b = 39
Check:-
17 + b = 56
17 + 39 = ?
17 + 39 = 56
Correct!
There were 39 books in her collection before her teacher donated her books.
The equation is: 17 + b = 56.
b = 39
14÷2.99=4.682274
hope this helps!
