1. whats the midpoint between (7,3) and (-3,-1)
Elanso [62]

Answer:

(2, 1 )

Step-by-step explanation:

Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is

( \frac{x_{1}+x_{2}  }{2}, \frac{y_{1}+y_{2}  }{2} )

Here (x₁, y₁ ) = (7, 3) and (x₂, y₂ ) = (- 3, - 1) , then

midpoint = ( \frac{7-3}{2}, \frac{3-1}{2} ) = ( \frac{4}{2}, \frac{2}{2} ) = (2, 1 )

A turtle laid 70 eggs and 9/15 hatched how many did not hatch
slavikrds [6]

Answer:

<h2><u>28 eggs did not hatch.</u></h2>

Step-by-step explanation:

<h3>1) Calculate 9/15 of 70 eggs. </h3>

\frac{9}{15}  × 70

= \frac{630}{15}

= 42

<h3>2) To calculate how many eggs <u>DID NOT</u> hatch, we should subtract 42 from 70.</h3>

70 - 42 = 28

<u>28 eggs did not hatch.</u>
