Question 1:

Add all the ratio numbers.

2+6+7=15

Now, divide that from 45, which is the given perimeter

45/15=3

Now, multiply the whole ratio by 3.

6:18:21

The shortest side is 6 inches.

Question 2:

Add all the ratio components.

17+16+12=45

Divide that by 180, the total degrees in a triangle.

180/45=4

Multiply that with 17 (largest ratio component).

You get 68, which is your answer.

Question 3:

(2x+7)/(3x-4) = 11/2

This proportion is quite simple and can be solved by setting the numerator equal to the numerator and the denominator equal to the denominator.

2x+7=11

3x-4=2

If you solve both of these, the value of x is 2.

That's your answer.

(Note: this is only a special case where you can do this)

Hope this helps! :)

Betty and Karen have been hired to paint the houses in a new development. Working together, the women can paint a house in two-t
mariarad [96]

Answer: 3 hours

Step-by-step explanation:

Here is the correct question:

Betty and karen have been hired to paint the houses in a new development. Working together the women can paint a house in two thirds the time that it takes karen working alone. Betty takes 6 hours to paint a house alone. How long does it take karen to paint a house working alone?

Since Betty takes 6 hours to paint a house alone, that means she can paint 1/6 of the house in 1 hour.

Karen can also paint 1/x in 1 hour

Both of them will paint the house in 3/2 hours.

We then add them together which gives:

1/6 + 1/x = 3/2x

The lowest common multiple is 6x

1x/6x + 6/6x = 9/6x

We then leave out the denominators

1x + 6 = 9

x = 9 - 6

x = 3

Karen working alone will paint a house in 3 hours.

Graph the inequality on the numberline and then write it in interval notation. 4-3y<-8
pogonyaev

First, let's simplify the inequality

\begin{gathered} \frac{4}{3}y

The graph looks like this:

Notice that the white dot is placed above the -6, it is important to include it like that.

Now, as an interval:

\begin{gathered} y

What is the solution to the system of linear equations y-x=4 and y+2x=1?
Maksim231197 [3]
 -x + y = 4
2x + y = 1
     -3x = 3
      -3    -3
        x = -1
2x + y = 1
2(-1) + y = 1
     -2 + y = 1
   + 2       + 2
         y = 3
  (x, y) = (-1,3)
