Answer:
A = 14.2/1.1 hours
B = 5.091 hours
Step-by-step explanation:
Formulate 2 simultaneous equations
5.7A + 6.8B = 111.40..........(1)
A +B =18...............................(2)
Multiply each item in (2) by 5.7 to get
5.7A + 5.7B = 97.2............(3)
subtract (1) - (3) on each side
5.7A -5.7A + 6.8B - 5.7B = 111.40 -97.2
1.1B = 14.2
B = 14.2 /1.1
to get A use equation (2)
A = 18 - B
A = 18 - 14.2/1.1 = 5.091
Answer:
<h2>60 days</h2>
Step-by-step explanation:
<h3>Step 1: First, since it is 1/6 pound twice a day, multiply by 2</h3>
1/6 x 2 = 1/3
<h3>Step 2: Divide 20 by 3 to get days that bag will feed the dog</h3>
20 ÷ 1/3 = 60
The bag will feed Nina's dog for 60 days.
I'm always happy to help :)
