Answer: y = - 1
Step-by-step explanation:
- Combine the like terms. -23y - 5 = 18
- Add 5 on both sides. -23y = 23
- Divide -23 on both sides. y = - 1
3/2=1 & 1/2
5/10 = 1/2
1&1/1/2 = 2
Answer:
(a) √25 rational
(b) √30 irrational
Step-by-step explanation:
Note : only perfect squares have rational roots
25 = 5² then 25 is a perfect square
therefore √25 = 5 is a rational number
30 cannot be written in the form a² where ‘a’ I start a natural number then 30 is not a perfect square
Therefore √30 is irrational.
