The answer to your question is 8.9
Answer:
The Large Box Weighs 18 kg, and the small box weighs 6.5 kg
Step-by-step explanation:
Let a= the weight in kg of a large box
Let b= the weight in kg of a small box
Multiply both sides of (1) by 4 and subtract (2) from (1)
1. 20a+8b=412
2. -3a-8b= -106
17a=306
a=18
and
5*8+2b=103
90+2b=103
2b=13
b=6.5
Answer:
So buddy this is going to get a bad rating I know but I'm going to help you out as much as I can without seeing a picture so for linear equations the formula is y=mx+b anyways the slope is m and to find it, look at the line and see how many times it goes up till it lands on a correct point. once you have that you can see how many times it went up and over. Because your slope is your rise over run (rise/run) and so for example <em>if</em> it was c then it would be 3/3 meaning it goes up 3 and over 3. So to find the right one just find a starting point and see how much it goes over to the right. if it goes over to the left then its negative instead of run over to the right. And if it goes down instead of rise then its negative. Hope this helps you find your answer now and in the future.
