Maria and Katy each have a piece of string. When they put the two pieces of string together end to end, the total length is 84in
Serga [27]

Answer: the length of Maria's piece of string is 45 inches.

the length of Katy's piece of string is 39 inches

Step-by-step explanation:

Let x represent the length of Maria's piece of string.

Let y represent the length of Katy's piece of string.

When they put the two pieces of string together end to end, the total length is 84inches. This means that

x + y = 84 - - - - - - - - - - - -1

Maria's string is 6 inches longer than Katy's. This means that

x = y + 6

Substituting x = y + 6 into equation 1, it becomes

y + 6 + y = 84

2y + 6 = 84

2y = 84 - 6 = 78

y = 78/2 = 39

x = y + 6 = 39 + 6

x = 45

Alina [70]

Answer:

The required equation is given by,

2 + \frac {13x}{4} = \frac {1}{2} + \frac {11y}{2}

Step-by-step explanation:

Let, each jar of  Liam's paint contains x quarts of paint.

Then, Liam's solution contains,

2 + 3\dfrac {1}{4} \times x  quarts of paint  or,

2 + \frac {13x}{4} quarts of paint

and,

let, each jar of Evan's paint  contains, y quarts of paint.

Then, Evan's solution contains,

\frac {1}{2} + 5 \dfrac {1}{2} \times y quarts of paint or,

\frac {1}{2} + \frac {11y}{2} quarts of paint

now, according to the question,

the required equation is given by,

2 + \frac {13x}{4} = \frac {1}{2} + \frac {11y}{2}
