C) 8 years old
D) 10 years old

Answers

Answer 1

Answer:

Answer:

The answer is B) 6 years

Step-by-step explanation:

First of all, build an equation. With the given problem, you can come up with:

s + c = 16

In which interprets that both their ages summed up are 16. Secondly,:

s = c + 4

After you will use the typical system of equations to solve. So, plug in the second equation to the first, where s will become c + 4, and the equation is now:

c + 4 + c = 16

And finally, solve for Charmaine's age.

2c + 4 = 16

-4 -4

-----------------

2c = 12

c = 6

Two number have a sum of 71 and a difference of 37

Answers

The right answer for the question that is being asked and shown above is that:

Two numbers have a sum of 71 and a difference of 37
x + y = 71
x - y = 37

So in order to get the two numbers, here it is:
x + y = 71
x - y = 37
------------
2x = 108
x = 54
y = 71 - 54
y = 17

So the two numbers are 54 and 17

17+54=71 and have a difference of 37.
