Three hundred two. You're welcome!
1 lb for 2.50
3 lbs for 4.25......4.25/3 = 1.42 per lb
5 lbs for 7.20......7.20/5 = 1.44 per lb
10 lbs for 15........15/10 = 1.50 per lb
The better deal (the cheapest one) = 3 lbs for 4.25 <==
Answer:
x = 7
Step-by-step explanation:
3x - 2 and 2x + 5 are alternate interior angles and congruent, thus
3x - 2 = 2x + 5 ( subtract 2x from both sides )
x - 2 = 5 ( add 2 to both sides )
x = 7
If x = 7 then a and b are parallel
2+6+18+54+162+486+1458+4375=6561
you multiply the previous number by three to find the next value
