Maksim231197 [3]

Answer:

(2.5 , 3.5)

Step-by-step explanation:

We can use the midpoint formula . Here the points are , (2,2) and (3,5) .

• Using Midpoint Formula :-

⇒ M = { (x1 + x2)/2 , (y1 + y2)/2 }

⇒ M = ( 2+3/2 , 5+2/2 )

⇒ M = ( 5/2 , 7/2 )

⇒ M = ( 2.5 , 3.5 )

<h3>Hence the midpoint is (2.5 , 3.5)</h3>

Olivia family drove to Disney land For spring break. Her mom and dad shared the driving duties for a total of 14 hours. her mom

Troyanec [42]

For this case we propose a system of equations:

x: Variable that represents the amount of hours that Olivia's mother drove

y: Variable that represents the amount of hours that Olivia's father drove

So, we have:

$x + y = 14\\65x + 60y = 895$

From the first equation we have:

$x = 14-y$

Substituting in the second equation:

$65 (14-y) + 60y = 895\\910-65y + 60y = 895\\-5y = 895-910\\-5y = -15\\y = \frac {15} {5}\\y = 3$

Thus, Olivia's father drove 3 hours.

$x = 14-3 = 11$

Olivia's mother drove 11 hours.

Answer:

$(x, y) :( 11,3)$
