Answer:
Joseph caught 7 tadpoles
Step-by-step explanation:
Let the number of tadpoles caught by Joseph be x
The number of tadpoles Wendy caught will be ;
9(x + 3)
After Joseph was upset, he released half of Wendy’s tadpole and then six times as many as Joseph caught swam away leaving Wendy with only three tadpoles left;
Hence, mathematically;
9(x + 3)/2 - 6x = 3
Multiply through be 2
9(x + 3) - 12x = 6
9x + 27 -12x = 6
9x -12x = 6-27
3x = 21
x = 21/3
x = 7
Yes correct

Answer:
∴73,563 calls are made between two cities with populations of 100,000 and 160,000 that are 435 miles apart.
Step-by-step explanation:
Given that,
The number of phone calls between two cities (N )
- directly proportional as the value of populations
and 
of two cities. - Inversely varies as the magnitude of distance (d).
Given that,
N=18,000, d=310 miles, =15,500 and =180,000
Now,
N=? , d=435 miles, =100,500 and =160,000
∴73,563 calls are made between two cities with populations of 100,000 and 160,000 that are 435 miles apart.
Let the number of stamps be s and the number of coins be c.
This means that s+c=300 and 3c+1.5s=825.
Multiplying the first equation by 3 yields 3s+3c=900.
Subtracting the second equation from this gives that 1.5s=75, and thus s=50.
It follows that c=250, so there are <u>2</u><u>5</u><u>0</u> coins.
