Answer:

15 centerpieces

Step-by-step explanation:

You have 6 centerpieces in 100 minutes (the easiest way is to apply proportion).

6/100=x/250

solve for x

x=(6/100)*250

x = 15 centerpieces

Answer:

y=3x+3

Step-by-step explanation:

the line doesnt connect with a negative so the first and third arent it. And the line cross's with a 3 not an x so the seconds on isnt the answer. Leaving the last one the answer.

Person A can paint the neighbor's house 5 times as fast as Person B. The year A and B worked together, it

LenKa [72]

Answer:

Person A paints the house in 12 days.

person B paints the house in 60 days.

Step-by-step explanation:

The together rate is the sum of each separate rate.

Person A can paint the neighbor's house 5 times as fast as Person B.

This means that the rate of person A is 1/x, and the rate of person B is 1/5x.

The year A and B worked together, it took them 10 days.

This means that:

$\frac{1}{x} + \frac{1}{5x} = \frac{1}{10}$

Multiplying everything by 10x

$10 + 2 = x$

$x = 12$

This means that:

Person A paints the house in 12 days.

person B paints the house in 60 days.
