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:
5
Step-by-step explanation:
Let's first find the slope of the linear function represented by the table:
As we move from x = 4 to x = 6 *an increase of 2), y increases by 6 from -2 to +4. Thus, the slope of this line is m = rise / run = m = 6/2, or 3.
Now we compare the two slopes: -2 and 3.
The postive difference between them is 5. This is Answer B.

Answer:
∠A = 88°
Step-by-step explanation:
= 180° - (50° + 38°)
= 180° - 88°
= 92°
∠A + 92° = 180°
∠A = 180° - 92°
∠A = 88°
