81,149, 274.... adding three numbers from the last would help you
like if you take 7 = 4 + 2 +1
or 13 = 7 + 4 +2
similarly 44+24+13 = 81
81+44 +24 = 149
149 + 81 +44 = 274
hope you get it!
3 times a # (# isn't specified, so you should use a variable): 3x
result is 5: =5
Put it all together: 3x=5
Well i have to say is that PEMDAS exponents first. Hope this helps.
Answer: B. y-1=2(x-3)
Step-by-step explanation:
First subtract both sides by 2x so it becomes -y=-2x-1
Second divide both sides by -1 so it becomes y=2x+1
After that to get it in the form they want it subtract 1 from both sides so that it becomes y-1=2x
Answer:
c=9
Step-by-step explanation:
Let's solve your equation step by step:
- add 6 on both sides
- divide 1.5 from the product of 6 and 7.5 (aka 13.5)
- you will get C
- put 9 in for C.

1. 
1.5 
2.
3. C=9
1.5(9)-6=7.5
13.5-6=7.5
