Hello from MrBillDoesMath!
Answer:
8
Discussion:
Let the number be "n". Then the question states that
3n - 15 = (n/2) + 5 => multiply both sides by 2
6n - 30 = n + 10 => subtract n from both sides
5n - 30 = 10 => add 30 to both sides
5n = 30 + 10 = 40 => divide both sides by 5
n = 40/5 = 8
Thank you,
MrB
Answer:
x = 5
Step-by-step explanation:
10/25 = (3x-1)/35

First you have to realize that when x>0 y becomes = - 2*x for any value of x greater than 0. Also true is that the circle representing the end point is open. With those two facts, only top left and bottom right can be true. Of those 2, the answer is top left because the point at 0 is open.
Answer:
all the possible values of y - x are 4 and 5
all possible values of x/y = 1
