Any number multiplied by 2 will give u an even number.
2 x 3 = 6
2 x 4 = 8
2 x 5 = 10
and any even number multiplied by 5 will end in 0
5 x 2 = 10
5 x 4 = 20
5 x 6 = 30
so the number in the ones place will be 0
Answer:
9d+3
Step-by-step explanation:
Distribute the Negative Sign:
=6d+5+−1(2−3d)
=6d+5+(−1)(2)+−1(−3d)
=6d+5+−2+3d
Combine Like Terms:
=6d+5+−2+3d
=(6d+3d)+(5+−2)
=9d+3
Now, since I don't want to actually work hard in class, I fail purposely to stay in normal and not advanced. However this is just a algebraic problem with fractions. Add 2/3 to both sides, (I dont know what that gives you) you then have t = whatever. Hope this helpful! :D <span />
1) The ratio of used books to all books is 6:14
2) The ratio of used books to new books is 6:8
x = # of ham sandwiches
14-x = # of turkey sandwiches ( as Lexi made 14 sandwiches)
as the question said that the number of ha sandwiches are 4 less than twice number of turkey sandwiches,
x = 2 * (14-x) - 4 = 24 - 2x
3x=24
x = 8
the number of ham sandwiches is 8, and the number of turkey sandwiches is 14-8=6
