71 and 60
Step-by-step explanation:
Let the numbers be A and B
Given one of the number is 11 more than the other ,
That’s
A = B + 11
And their sum is 131
That’s
A + B = 131
We now have two expressions
A = 11 + B and
A + B = 131
Now, substitute B + 11 for A into the second expression.
We have
A + B = 131
11 + B + B = 131
11 + 2B = 131
Subtract 11 from both sides
11 - 11 + 2B = 131 - 11
2B = 120
Divide both sides by 2
B = 120/2
B = 60
Substitute 60 for B in either expressions to get A
Using the first expression, we have
A = 11 + B
A = 11 + 60
A = 71
The numbers are 71 and 60
Ответ:
B is your answer.
Step-by-step explanation:
Depends on 18/36 = 72/444, because 444 doesn't make sense at all. None of the others are equivalent. If it's 72/144 then this is the answer
Hope this helps.
