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:
Option (c) 7.3
Step-by-step explanation:
Since is forms a right angled traingle,
a= 3+4= 7
b = 4-2= 2
c = AB
Pythagorean theorem:
a^2+b^2 = c^2
So since we know a and B but the hypotenuse (c) is missing
7^2 + 2^2 = c^2
c^2 = 49+4
= 53
c = √53
= 7.28 rounded off to 7.3
So the length of hypotenuse or c is 7.3 units
Therefore, the length is 7.3

15cm
Step-by-step explanation:
Answer:
5.00 is the value of the initial balance (i.e. when time is 0) in the savings account.
Step-by-step explanation:
We have the function, 
which represents the balance in the savings account.
Now, if we substitute x= 0, we have,
implies 
As, 'any number with power 0 is equal to 1 i.e. 
'.
We get,
implies 
i.e. f(0)= 5.00
Thus, we see that,
5.00 is the value of the initial balance (i.e. when time is 0) in the savings account.
