Answer:

10 milligrams of Medication A

Step-by-step explanation:

We'll write proportions/ratios for this:

20:16 is the usual proportion, and x:8 is this week's dose. The ratio from A to B has to be equal, so

20/16 = x/8

Cross-multiply:

(20)(8) = (16)(x)

160 = 16x

divide both sides by 16

x = 10

Using the digits 0-9, no more than one time each, place a digit in a box to create an equation with a solution x= -1/2

Brums [2.3K]

Three equations are:

2x+1=6x+3

8x+6=2x+3

8x+4=2x+1

<u>Step-by-step explanation:</u>

Using the digits 0-9, no more than one time each, place a digit in a box to create an equation with a solution x= -1/2 . We need to Create three equations. Formula is below. __ x+ __=__ x+ __ . Let's find out:

2x+1=6x+3

Let's verify this :

⇒ $2x+1=6x+3$

⇒ $4x=-2$

⇒ $x=\frac{-1}{2}$

8x+6=2x+3

Let's verify this :

⇒ $8x+6=2x+3$

⇒ $6x=-3$

⇒ $x=\frac{-1}{2}$

8x+4=2x+1

Let's verify this :

⇒ $8x+4=2x+1$

⇒ $6x=-3$

⇒ $x=\frac{-1}{2}$
