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:
Option A. 36
Step-by-step explanation:
Let
x-------> the number of boys
y------> the number of girls
we know that
-----> equation A
-----> equation B
using a graphing tool to solve the system of equations
Remember that the solution is the intersection point both graphs
The solution is the point (36,6)
see the attached figure
therefore
The number of boys is 36
