Let us assume that the age of Janet's sister is = x
Then the age of Janet = x + 5
Now we also know that their combined age is equal to 51 years. Then we can write the equation as
x + (x + 5) = 51
2x + 5 = 51
2x = 51 -5
2x = 46
x = 46/2
= 23
So the age of Janet = x + 5
= 23 + 5
= 28 years
So the age of Janet's sister is 23 and Janet's age is 28

Answer:
The correct option is A
Step-by-step explanation:
The question is incomplete because the options are not given for the question. Lets complete the question first. The options for this question are given below.
A) (-1)(7+7+7)
B) (-7)+(-7)+(-7)+(-7)
C) 7+7+7
D) 7+7+7+7
Now look at the conditions given. Supoose at 4pm, the temperature is x°F at 4pm. As temperature is decreasing 7°F every hours, and it happenss for 4 hours.
We can say that after one hour, temperature is:
5pm: x°F - 7°F
After two hours:
6pm: x°F - 7°F - 7°F
After three hours:
7pm: x°F - 7°F - 7°F - 7°F
Hence, the expression is given by:
-7 - 7 - 7
or
(-1)(7+7+7)
It has to be 24.
Because 8 is not divisible by 3 or 6 it must be a multiply of two of the numbers. 3*6=18 but 8 is not divisible by that. 3*8 = 24. 24 is divisible by 3 (8), 6 (4), and 8 (3). So 24 is the answer.
