xxMikexx [17]

Answer: (2.5  ;  1.5 )

Step-by-step explanation:

  • The midpoint of the segment with the points \bf  ( x_1  \ ;  \ y_ 1) and \bf (x_2 \  ;  \ y_2)  is calculated by the formula:

  • \bf (x _0  \ \ ;  \ \ y _0) = \bigg(\dfrac{x_1+x_2}{2} \ ; \  \dfrac{y_1+y_2}{2}  \bigg)  
  • Then :
  • \bf (x_0 \  ;  \ y_ 0)=\bigg( \dfrac{3+2}{2}  \ \ ;  \dfrac{4-1}{2}  \bigg)  =( 2.5  \  \ ; \ \  1,5 )

34kurt

Answer:

$3.75

Step-by-step explanation:

. Chocolates = $2

. Only has to spend $30

. Milk costs $4

30 divided by 2 = 15

15 divided by 4 = $3.75

To Check: 3.75 x 4 = 15

15 x 2 = $30

Explain: All you have to do is divide 30 by 2 and you will get 15. Then, divide 15 by 4 and you will get $3.75. When you check, you should use the inverse operation which is multiplication, so with that being said, 3.75 x 4 = $15.  15 x 2 = $30.

Your welcome!
