Draw a right triangle (attachment below):
Length of the vertical line = 6 units
Length of horizontal line = 8 units
a^2 + b^2 = c^2
6^2 + 8^2 = 100
Square root of 100 = 10
The distance between the two points is 10 units.
The solution is r= 7/a-x How did i do this?
Your equation is ax+ r=7, so the goal is to isolate the r. You begin by dividing the a from the ax. Remember, what you do to one side, you must do to the other. So you do 7/a, since you can't simplify 7/a, leave it as it is. Next, your equation should look like this x+r=7/a. In order to isolate the r, you move the x to the other side by subtracting, which leaves you with the answer of r= 7/a-x.
Hope this helped!
Answer:
0.375 pounds of melon was given away by Melanie.
Step-by-step explanation:
We are given the following in the question:
Initial weight of melon =

Wait of remaining piece =

Pounds of melon Melanie gave away =
