Answer:
3x + 2y = 38, 3a + 2b = 38
Step-by-step explanation:
An equation may be defined as a statement that shows two mathematical expressions to be equal. It is to equate one thing to another thing.
In the context, two different equations for the situations are :
i). Let the shirt be represented by x
And the socks be represented by y
Therefore, according to the question,
3x + 2y = 38
ii). Let the shirt be represented by a
And the socks be represented by b
Therefore, according to the question,
3a + 2b = 38

Answer:
0.714 mins
Step-by-step explanation:
by using the rule of three:
180 mins----->252 ballons
x----------------1 ballon=0.714 mins
To factor, you split the equation so the factors multiply to get the whole equation.
(x-2)(x+2)
Then, interpret the factors.
The zeros can be found at (2,0) and (-2,0).
x=2, x=-2
