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.
2(4k+8)=10
8k+16=10 (she said 2k instead of 8k)
To continue solving, subtract 16 from both sides. That would give you 8k= -6. Then divide both sides by 8, and get -6/8 which equals -3/4.
Answer:
Solving with an equality is just simply the same as solving any algebra equations. If you were given a fraction, then just multiply both sides.
Example:
4 +
> 14
Subtract 4 on both sides:
4 - 4 +
> 14 - 4
> 10
Now <em>multiply both sides by 2</em>:
× 2 > 10 × 2
x > 20
