Sorry knoww the answer not
Unicycle has 1 seat and 1 wheel.
Bicycle has 1 seat and 2 wheels.
u + b = 21
u + 2 b = 30 ⇒ u = 30 - 2 b
--------------------------------------
30 - 2 b + b = 21
30 - b = 21
b = 9, u = 30 - 18 = 12
There are 12 unicycles and 9 bicycles.
An equation in slope-intercept form:
u + b = 21
u = - b + 21
Answer: A ) u = - b + 21
Answer:
37.50
Step-by-step explanation:
2/5x + 15 = 30
