Hi there! The answer is C. - 2

8d - 4d - 6d - 8 = 2d
First we collect the terms.

- 2d - 8 = 2d
Next subtract 2d from both sides.

- 4d - 8 = 0
Add 8 to both sides.

- 4d = 8
Finally divide both sides by -4.

d = \frac{8}{ - 4} = - 2
Therefore, the answer is C. -2

~ Hope this helps you!

<span>8d – 4d – 6d – 8 = 2d

Combine common terms:
-2d - 8 = 2d

Add 2d to both sides:
-8 = 4d

Swtich sides:
4d = -8

Divide both sides by 4:
d = -2

Answer: - 2

there is a beaker of 3.5% acid solution and a beaker of 6% acid solution in the science lab. Mr. Larson needs 200ml of 4.5% acid
disa [49]
Below are the choices:

A. 80 mL of the 3.5% solution and 120 mL of the 6% solution 

<span>B. 120 mL of the 3.5% solution and 80 mL of the 6% solution </span>

<span>C. 140 mL of the 3.5% solution and 60 mL of the 6% solution </span>

<span>D. 120 mL of the 3.5% solution and 80 mL of the 6% solution
</span>
Let fraction of 3.5% in final solution be p. 

<span>p * 3.5 + (1 - p) * 6 = 4.5 </span>

<span>3.5p + 6 - 6p = 4.5 </span>

<span>2.5p = 1.5 </span>

<span>p = 3/5 </span>

<span>3/5 * 200 = 120 </span>

<span>Therefore the answer is B. 120 ml of 3.5% and 80 ml of 6%.</span>
