Answer:
6x + 1
Step-by-step explanation:
Distribute
3 + 2 ( x- 1 ) + 4x
3 + 2x - 2 + 4x
Subtract
3 + 2x - 2 + 4x
1 + 2x + 4x
Like terms
1 + 2x + 4x
1 + 6x
Rearrange
6x + 1
Answer:
Rule: If it ends with a 0, 2, 4, 6, or 8 it is divisible by 2
for divisibility rule of 3 add all digits if it is a part of the table of 3 it is divisible
Rule: If the last two digits are a multiple of 4
(or if the last two digits are 00) for 4
Rule: If the last two digits are a multiple of 4
(or if the last two digits are 00) for 5
Rule: If it is divisible by 2 and by 3 for 6
Rule: If the sum of the digits are a multiple of 9 for 9
Rule: If the last digit is 0 for 10
4. 25.12 ft
5. 40.82 ft
6. 21.98 ft
(I used 3.14)
4b=a then plus 10 to see if the age holds true to 3b=a in ten years. Then since the question is how old is she today? You must either add 6 to young age (of20) or minus 4 from the older (of 30).
So Betty would be 26 today.
