Answer:
(V + W) * 5 = 175 boat traveling downstream
(V - W) * 7 = 189 boat traveling upstream
V + W = 35
V - W = 27
2 V = 62
V = 31 = speed of boat
2 W = 8
W = 4 speed of water
Upstream 7 * (31 - 4) = 189
Downstream 5 * (31 + 4) = 175
1 ÷ 3 = 3 × 3 = 9
So you would have 9 1/3 chicken pot pie pieces
Answer:
23
Step-by-step explanation:
You can use Euler's method to find the GCF of these values:
(9n -2) mod (7n +3) = 2n -5
(7n +3) mod (2n -5) = n +18
(2n -5) mod (n +18) = n -23
We want this to be zero, so n = 23. (Note that none of the other remainders are zero for any positive integer n.)
The smallest positive integer n for which (9n-2) and (7n+3) share a common factor is 23. (Their common factor is 41.)

9(23) -2 = 205 = 5×41
7(23) +3 = 164 = 4×41
Let t=original amount of soup
8/15 of t is 140
“Of” means multiply, “is” means equal to
Therefore
8/15t=140
t=140*15/8
t=262.5
Hope this helped :)
