Solve for a. 2.4a + 8 = 27.2

Hello! a = 8

Step-by-step explanation:

2.4 × 8 = 19.2

19.2 + 8 = 27.2 therefore a = 8 hope that helps!

a = 8

Step-by-step explanation:

2.4a + 8 = 27.2

2.4a + 8 - 8 = 27.2 - 8

2.4a = 19.2

2.4a ÷ 2.4 = 19.2 ÷ 2.4

a = 8

for the friend request.

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.  

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.  

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.
