Hey there!
Let's think of this with a simpler example. Let's say one package is 4 pounds and one is 2 pounds. How many times heavier is the first than the second?Well, two, because the first package is double the weight of the second package! It's twice as heavy! And to get to that number, we divide four by two!
So, in our actual problem, we just divide 3.92 (bigger package) by 2.8 (smaller package).
3.92÷2.8=1.4
So, the first package is 1.4 times heavier than the first one!
Have a wonderful day!
Hello,
Answer B
Is y=(5,t) a solution of -5x+y=-40
==>-5*5+t=-40
==>t=-40+15
==>t=-15
Now change the t to y (all is done to make you not to find the answer)
y=-15.
The answer is 63°.
I hope this helps (:
