Is there a picture included?
Step-by-step explanation:
You need to find common denominators. 15 . so you have to multiply the 5 from 2/5 by three and the 2 by three to get -6/15. then multiply the four from 4/3 by 5 to get 20 and the 3 by five to get 15, so 20/15. adding a negative is like substracting so 20/15 - 6/15 . 20-6= 14. so its 14/15
Answer:
-3x-7
Step-by-step explanation:
Answer:
(E) 27
Step-by-step explanation:
Let the 5 digit palindrome be PQRQP
Since each digit is chosen from 1,2,3 therefore
P can either be 1,2 or 3 which gives us 3 options.
Q can also either be 1,2 or 3 which gives us 3 options
R can either be 1,2 or 3 which also gives us 3 options
So we have 3^3 = 3*3*3
= 27
This means 27 palindromes are possible if they are formed using one or more of the digits, 1, 2, 3.
