Somebody please help

Line A slope = 3/2

Line B slope = 2

Step-by-step explanation:

We create the triangles they request for each line, as shown in the attached image, which we use to calculate the vertical change (height of the triangle) and horizontal change (base of the triangle). The height and base of the triangles (depicted in red and blue matching the color of the lines) have been highlighted for easy identification.

We estimate the vertical and horizontal changes, as well as the slope, for each line as shown below:

Line A:

vertical change = (6 - 3 ) = 3

horizontal change = (2 - 0) = 2

slope of line A = 3 / 2

Line B:

vertical change = (6 - 4) = 2

horizontal change = (3 - 2) = 1

slope = 2 / 1 = 2

10.416 meters per second

step-by-step explanation:

distance=1 00 meters

time= 9.6 seconds in decimal form or 9 3/5 as a mixed number

average speed= 100/9.6

=10.416 meters per second or 10 52/125 as a mixed number.

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15
