Anthony has a cup full of nickels and dimes worth $6.80. There are 82 coins all together.
Which of the following systems of equations correctly models this situation?
x+y= 680
5x+10y = 82
B. 5x+10y = 680
x+y=82
5x +y = 680
x+10y = 82
D. 5x+y=82
x+10y = 680

Consider this equation. |y + 6| = 2 what can be concluded of the equation? check all that apply. there will be one solution. there will be two solutions. the solution to –(y + 6) = 2 will be also be a solution to the given absolute value equation. the solution(s) will be the number(s) on the number line 2 units away from –6. the value of y must be positive since the variable is inside absolute value signs.
