1 answer:
Nancy bought 177 long sleeve and 354 short sleeve shirts.
{x+y=531, y=2x} represents the system of equations for this problem.
Step-by-step explanation:
Let,
x be the long sleeve shirts
y be the short sleeve shirts
Total shirts bought = 531
According to given statement;
x+y=531 Eqn 1
y = 2x Eqn 2
Putting value of y from Eqn 2 in Eqn 1;
Dividing both sides by 3;
Putting x=177 in Eqn 2
Nancy bought 177 long sleeve and 354 short sleeve shirts.
{x+y=531, y=2x} represents the system of equations for this problem.

Answer:
Shortest side = 7 inches.
Medium side = 9 inches.
Longest side = 10 inches.
Step-by-step explanation:
Let the shortest side be x.
Translating the word problem into an algebraic equation, we have;
Shortest side = x
Medium side = x + 2
Longest side = x + 3
The perimeter of a triangle is given by the addition of all its three (3) sides.
Mathematically, the perimeter of a triangle is given by the formula;
Substituting into the equation, we have;
26 = x + x + 2 + x + 3
26 = 3x + 5
3x = 26 - 5
3x = 21
x = 21/3
x = 7 inches.
<em>Therefore, the length of the three sides are;</em>
<em>Shortest side = x = 7 inches. </em>
<em>Medium side = x + 2 = 7 + 2 = 9 inches. </em>
<em>Longest side = x + 3 = 7 + 3 = 10 inches. </em>
