Kayra and Mycho sell flowers on weekends to earn extra money.For every 2 flowers that Kayra sells,Mycho sells 5. If Kayra sold 6
andreyandreev [35.5K]

Answer:

We know that:

For every two flowers that Kayra sells, Mycho sells 5.

Now, in the question we have:

"If Kayra sold 6 newspapers, how many did Mycho sell?"

There is no information about newspapers, so we can't answer anything.

If we had something like:

"If Kayra sold 6 flowers, how many did Mycho sell?"

Well, in this case, we remember that for every 2 flowers that Kayra sells, Mycho sells 5, then the first thing we need to do is count how many groups of 2 flowers we have in 6 flowers, this is:

6/2 = 3 groups.

And for each one of these, Mycho will sell 5 flowers, then the total number of flowers that Mycho sold is:

3*5 = 15 flowers.

Help please answer this .... is this bettter?
iris [78.8K]

Answer:

x = 53 degrees

Step-by-step explanation:

Alternate exterior angles are equal if  two parallel lines are cut by a transversal.

 If  m and n are parallel, then

3x-28 = 2x+25

Subtract 2x from each side.

3x-28-2x = 2x+25-2x

x-28 =25

Add 28 to each side.

x-28+28 = 25+28

x = 53
