Answer:
<em>-4 ≤ y ≤ 7</em>
Step-by-step explanation:
<u>Inequalities</u>
Solve the system of inequalities:
4y - 7 ≤ 3y [1]
3y ≤ 5y + 8 [2]
A.
Subtracting 3y to [1]:
y - 7 ≤ 0
Adding 7:
y ≤ 7
Subtracting 5y to [2]:
-2y ≤ 8
Dividing by -2 (and flipping the sign):
y ≥ -4
The solution of the system is all the values of y greater or equal to -4 and less or equal to 7.
B.
The solution can be expressed as:
-4 ≤ y ≤ 7

Answer:
3/4 sheet of construction paper each
Step-by-step explanation:
Think: That's "3 sheets for 4 friends." We can reduce this by dividing both quantities by 4:
3/4 sheet for each of 1 friend, or 3/4 sheet per friend.
