Solution:
Let each pond of jelly beans cost $x.
and each pond of almonds cost $y.
Then we can write
Now solve these two equations together using substitution we get
Hence each pond of jelly bean cost 1.25$
Each pond of almond costs 2.25$
1.679 kg * (40 min)/(kg) + 20 min = 67.16 min + 20 min = 87.16 min
don't be alarmed the two lines just mean absolute value, the problem is asking what is m. the problem is asking what number multipyed by 2, subtracted by 1 will give you 3?
2x2=4 right?
so 4-1=3 there!
m=4
so the problem is 2(4)-1=3
i hope i explained well enough!
The first sequence, it is increase +1 for every number, because 2-3 is 1, 3 - 5 is 2, and 5 - 8 is 3. So, lets add 4 to 8, and we will know the next number of the sequence.
4 + 8 = 12
So, the next number in the first sequence is:
1, 1, 2, 3, 5, 8, 12
Second Sequence:
The second equation is doing exactly the same thing (it increases by 1 every number it goes) just this one is decreasing.
Proof: 26 - 24 is 2, 24 - 21 is 3, and 21 - 17 is 4.
Lets subtract 5 to 17 to know the next number.
17 - 5 = 12
So our next number is:
26, 24, 21, 17, 12
Ok so
you can make a 10 with the 9
23+9=20+3+9=20+2+1+9=20+2+10=20+10+2=30+2=32
