Answer:

x = 4

Step-by-step explanation:

the dimensions of the small triangle to the large triangle are increasing by multiplying by 5.

5 times 5 equals 25

3 times 5 equals 15

so 4 times 5 equals 20

then, you have to solve the equation:

20 = 3x + 8

subtract 8 from both sides

12 = 3x

divide both sides by 3

12 divided by 3 equals 4

so x = 4

(x, 7) and (11, 8); m = -1/5<br> Plz help
Kay [80]

Answer:

This tells us that the line with slope -1/5 passes through the two points (16, 7) and (11, 8).  The previously unknown x-coordinate is 16.

Step-by-step explanation:

A line with slope m = -1/5 passes through the points (x, 7) and (11, 8).  Find the value of x.

The slope of the line through these two points is found from the slope formula and is:

        8 - 7

m = ----------- and the value of m is given as -1/5.  Therefore,

         11 - x

           1

m = ----------- =  -1/5

         11 - x

Cross-multiplying, we get (1)(5) = -(11 - x), or 5 = -11 + x.  Then x = 16

This tells us that the line with slope -1/5 passes through the two points (16, 7) and (11, 8).  The previously unknown x-coordinate is 16.
