Answer:
23/10
Step-by-step explanation:
To find the unit rate divide 84 by 36
84 ÷ 36 = 2.3
To convert 2.3 to a faction
2.3 = 2.0 + 0.3
0.3 = 3/10
3/10 + 2 = 2 3/10
2 3/10 = 23/10
Answer:
x^2 + 2x - 8
Step-by-step explanation:
h(x) + k(x) = (2x^2 + 5x - 12) + (-x^2 - 3x + 4)
Add Like Terms
(2x^2 + 5x - 12) + (-x^2 - 3x + 4)
2x^2 - x^2 = x^2
(2x^2 + 5x - 12) + (-x^2 - 3x + 4)
5x - 3x = 2x
(2x^2 + 5x - 12) + (-x^2 - 3x + 4)
-12 + 4 = -8
x^2 + 2x - 8
Answer:
An infinite number.
Step-by-step explanation:
There are many, many rational fractions between -6 and -5.
For example, take the numbers - 5 2/7 and - 5 4/7. there is another rational between these - 5 3/7.
Then we have another between - 5 2/7 and - 5 3/7 which is - 5 5/14, - and we could go on doing this all day and never coming to an end!!
