Answer:

  16 tricycles

  12 bicycles

Step-by-step explanation:

If all were bicycles, there would be 28·2 = 56 wheels. Each additional wheel indicates the presence of a tricycle instead of a bicycle.

There are 72 -56 = 16 tricycles. The remaining 28-16 = 12 are bicycles.

Hello!

First you find out the amount of balloons by adding them up

10 + 12 + 15 + 8 = 45

Then you add all the balloons that are not green

10 + 12 + 15 = 37

Then you put the amount of balloons that are not green over the total amount of balloons

The answer is 37/45

Hope this helps!

X=y-1 y=(4-2x) solve by substition
Nataliya [291]
Since you have an equation equal to both x and y, you can either substitute the equation equal to x for x or the equation equal to y for y.
x=y-1
y=4-2x
I would substitute the y in using 4-2x
x=(4-2x)-1
x=3-2x
3x=3
x=1
Then plug in x and solve for y
1=y-1
2=y
