Anastasy [175]

Answer:

The answer to your question is: (8, -2)

Step-by-step explanation:

Data

A (9, -16)

L (7, 12)

Formula

$Xm = \frac{x1 + x2 }{2} Ym = \frac{y1 + y2}{2}$

Xm = $Xm = \frac{9 + 7}{2} Ym = \frac{-16 + 12}{2}$

Xm = 8 Ym = -2

How many liters of a 35% salt solution must be mixed with 20 liters of 70% salt solution to obtain a solution that is 45% salt?

Tomtit [17]

Answer:

.35 x + .70 (20) = .45(x+20)

50=x

Step-by-step explanation:

Let x = liters of 35% salt solution

We have 20 liters of 70%

We have a total of 20+x liters of 45%

.35 x + .70 (20) = .45(x+20)

Distribute

.35x + 14 = .45x +9

Subtract .35x from each side

14 = .10x +9

Subtract 9 from each side

5 = .10x

Divide each side by .1

5/.1 = x

50=x
