Hello from MrBillDoesMath!
Answer:
One example is 52 and 54. They are between 50 and 60 and have the factor 2 in common
Discussion:
Consider the numbers between 50 and 60:
51, 52, 53, 54, 55, 56, 57, 58, 59
53 and 59 are primes so they don't have any factors in common and we can focus on the other numbers in the range.
Consider 52. It's even so is divisible by 2 as are 54, 56, 58. So 52 and 54 , for example, are are two number between 50 and 60 that have the factor 2 in common
Even number are visible by 2. Let's look for numbers visible by 3. How about 54 ( = 18 *3) and 57 ( = 19*3)? That works so its looks like there are many answers to this question.
Thank you,
MrB

Explanation
Step 1
Let
x represents the smallest number:
as those are three consectutive intergers, the next interger is:
this is the middle number:
middle number=x+1
the next consectutive number is
so, the third number is x+2
Hence,
Step 2
the sum of the smallest number and twice the middle
number is equal to 20 more than the third number?
replacing:
twice the middle=2(x+1)
so, the answer is
D
Answer:
Fred will have "C
" $1,348.18 after 3 years
Step-by-step explanation:
where,
Principal (P) = $1,000
rate = 10% = 0.10
Time (t) = 3 years
m = 12
Finding the accumulated amount
A =
A =
A = 1000 (1.0083)³⁶
A = $1346.578
