a student earns $11.75 per hour for gardening. if she worked 21 hours this month, then how much did she earn?

$246.75

Step-by-step explanation:

11.75 x 21 = 246.75

hope this helps <3

If the student worked 21 hours this month, she will earn $246.75.

Step-by-step explanation:

Let equal hours.

If the student earns $11.75 per hour, we can represent this with the expression:

If she worked 21 hours this month, then:

With that information, we can substitute for in the initial expression:

Multiply:

Therefore, if the student worked 21 hours this month, she will earn $246.75.

We can check our work by setting the initial expression equal to our solution:

Divide both sides of the equation by the coefficient of , which is :

Since this quotient matches the number of hours she worked, our solution is correct!

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'.
