3. d-6 = -10 4. m-14=-17 5. w-23=59 6. x-57= -15 7. x-31= -7 8. x + 51= -9

SVEN [57.7K]

Answer: 3. d= -4 , 4. m= -3 , 5. w= 82 , 6. x=42 , 7. x=24 , 8. x= -60

Step-by-step explanation:

3. Step 1: Add 6 to both sides.

d−6+6=−10+6

d=−4

4. Step 1: Add 14 to both sides.

m−14+14=−17+14

m=−3

5. Step 1: Add 23 to both sides.

w-23+23=59 + 23

w= 82

Continue to repeat the step for the other ones. If there is a positive then subtract on both sides!

A nurse must mix a 20% solution of medication in an existing container of water. The container currently holds 12 ounces of wate

gayaneshka [121]

Answer:

3 ounces of medication to be added to get 20%solution of medication

Step-by-step explanation:

To find:

The amount of medication to be added to 12 ounces of water to get a 20% solution

Let the amount of medication to be added =x

So total amount of mixture = amount of water + amount of medication

= 12+x

% medication = (amount of medication÷total amount of the mixture)× 100

Therefore

% medication =( x÷12+x)×100

20 =( x÷12+x)×100

$20 =\frac{x}{12+x}$ X 100

20(12+x) =100x

240+20x =100x

100x-20x =240

80x =240

x =240÷80

x=3

so 3 ounces of medication to be added to get 20%solution of medication
