Let s equal the number of shirts she can buy
140 > $28.50 + $20.75s
111.50 > 20.75s
5.37 > s
so we round down. she can buy 5 shirts, plus the one dress and she would spend less than $140
Answer:
Graph 1: Consistent Dependent
Graph 2: Consistent Independent
Graph 3: Consistent Dependent
Graph 4: Inconsistent
Step-by-step explanation:
Consistent means they have at least one solution. So lines that intersect once or lines that intersect infinitely many times are both consistent systems.
If they are the system that has one solution they are considered independent.
If they are the system that has infinitely many solutions then are considered dependent.
Inconsistent means they won't intersect at all.
First graph shows the same line graphed onto itself. That means they have infinitely many solutions and is therefore a consistent dependent system.
Second graph shows the lines intersecting once. That means they have one solution and therefore is a consistent independent system.
Third graph shows the same description of graph one and is therefore a consistent dependent system.
The last graph shows parallel lines. Parallel lines do not intersect and therefore do not have a solution. So this system is inconsistent.

Answer:131/12
Step-by-step explanation:
-7 2/3 -5 1/2 +8 3/4 = 23/3 - 11/2 + 35/4 = 92/12 -66/12 +105/12 = 131/12
Answer:
D -- the last one
Step-by-step explanation:
The formula tells you what to do.
t = 3
A0 = 25
A(t) = ?
A(3) = 25 * (1/2)^3
A(t) = 25 * 1/8
A(t) = 25/8
A(t) = 3.125
