Answer:
28 blue bikes
Step-by-step explanation:
There follows a relatively simple method for solving this problem:
Let c be a counter. Then 4c + 5c = 63, and 9c = 63. Thus, c = 7.
Then the number of blue bikes is 4(7) = 28, and the number of black ones is 5(7) = 35. Note that 28 + 35 comes to 63.
There are 28 blue bikes.
Answer:
7 hamsters at 5 pesos each and 13 hamsters at 8 pesos each
Step-by-step explanation:
5x + 8y = 139
x + y = 20
x = 20 - y
5x + 8y = 139
5(20 - y) + 8y = 139
100 - 5y + 8y = 139
100 + 3y = 139
3y = 139 - 100
3y = 39
3y/3 = 39/3
y = 13
x + y = 20
x + 13 = 20
x = 20 - 13
x = 7
