Step-by-step explanation:
Answer:
8 capsules
Step-by-step explanation:
325 milligrams into grams =0.325
so 2.6/0.325= 8
so 8 capsules should be given
First, let's multiply the first equation by two on the both sides:
<span>8x + 7y = 39 /2
</span>⇒ 16x + 14y = 78
Now, the system is:
<span>16x + 14y = 78
</span><span>4x – 14y = –68
</span>
After adding this up in the column:
(16x + 4x) + (14y - 14y) = 78 - 68
20x = 10
⇒ x = 10/20 = 1/2
y can be calculated by replacin the x:
<span>8x + 7y = 39
</span>⇒ 8 · 1/2 + 7y = 39
4 + 7y = 39
7y = 39 - 4
7y = 35
⇒ y = 35 ÷ 7 = 5
If it's compounded annually, it basically means the interest rate will apply once a year.
So the answer will be 1.
6x - 12 = 2x + 36
4x = 48
x = 12
4y = 6y - 42
-2y = -42
y = 21
