Answer:
The number of bicycles is 19.
and the number of tricycles is 4.
Step-by-step explanation:
As we know that the number of seats in bicycles as well as in tricycles is 1.
The number of wheels in bicycles is 2
and the number of wheels in tricycles is 3.
Let the number of bicycles be x.
and the number of tricycles be y.
Thus using the given information we can make equation as,
x + y = 23
and, 2x + 3y = 50
Solving these two equations:
We get, x = 19 and y = 4
Thus the number of bicycles is 19.
and the number of tricycles is 4.
The value of c that makes the equation true is: c = -13/21.
<h3>What is an Equation?</h3>
An equation is a mathematical statement whose values on the right and left sides are equal.
Given:
c + 15 = 23c + 2 − 43c
Find the value of c
c + 15 = -20c + 2
c + 20c = -15 + 2
21c = -13
c = -13/21
Thus, the value of c that makes the equation true is: c = -13/21.

Assuming you retain the same number of pounds of popcorn (3)
find cost now
3*0.80=2.40
2.20 per pound
(2.4+2.2x)/(3+x)=1.6
times 3x both sides
2.4+2.2x=4.8+1.6x
minus 1.6x from both sides
2.4+0.6x=4.8
minus 2.4 both sides
0.6x=2.4
divide both sides by 0.6
x=4
