Answer:

(2,7)

Step-by-step explanation:

n=2p+3

n=5+p

We can combine the equation to a simpler equation

5+p=2p+3 to get p=2p+-2

-p=-2 or p=2

We can plug this in to get n=5+2 to get n=7

PLEASE HELP ME ASAP!!

Answer:

(0.5, 0.5)

Step-by-step explanation:

Use the midpoint formula: $(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})$

The points are:

A(-2, 4)
C(3, -3)

$(\frac{-2+3}{2},\frac{4-3}{2})\\\\(\frac{1}{2},\frac{1}{2})$

Therefore, the midpoint between A and C is located at (0.5, 0.5).

a box half full of apples weighs 40kg and the same box one fifth full weighs 22kg, what does the box weigh when empty?

ruslelena [56]

1/2 = 40kg
1/5 = 22kg
1/2 = 5/10
1/5 = 2/10
3/10 is the difference between 18kg.
This means 1/10 of the box filled with apples is 6kg.
40 - (5 x 6) = 10kg. The box weighs 10kg alone.
