Brittney has twice as much money as Sun. Together, they have $60. Let x represent the amount of money Sun has. What expression represents the amount of money Brittney has? What expression represents the amount of money that Brittney and Sun have together? What is the equation described in this problem?

Sun's money = x

Brittney's money = 2x

x + 2x = $60

3x = $60

3x/3 = 60/3

x = 20

So amount that Brittney has is 2x.

The amount they have together is 3x

The equation that describes the problem is 3x = $60

Jeremiah's answer was -91.

Step-by-step explanation:

Jeremiah's tutor gave him a math problem to solve.

Given problem: 546 ÷ − 6

Since 546 ÷  6 = 91

Then,  546 ÷ − 6 = -(546 ÷  6) = -91      [∵ In integers (a÷(-b))= (-a ÷b)= - (a÷b)]

If Jeremiah's answer was correct , then the answer would be -91.

Hence, Jeremiah's answer was -91.
