Answer:
(11y-36 degrees)=63 degrees
Step-by-step explanation:
<span>2.75x + 3.25y = 215
</span>
answer is the last one (D)
0.3(12y)
= 3.6y
hope this helps :)
For the first blank, the answer should be the total weight of the solution which is derived from adding 5 grams and 20 grams. The answer would be,
T = 5 + 20 = 25 grams
For the second blank, the % solution is derived by dividing the amount of salt initially by the total amount of the resulting solution. This is as shown below.
C = ((20 x 0.5) / 25) x (100%)
Simplifying,
C = 40%
Answers:
a. 25 grams
b. 40%
