Ten less than a number is equal the same number divided by 2 what is the number

x-10=x/2

Simplify both sides of the equation.

x−10 = x /2

x+-10 = 1/2 x

x-10 = 1/2 x

Subtract 1/2 x from both sides.

x-10-1/2 x = 1/2 x - 1/2 x

1/2 x-10 = 0

Add 10 to both sides.

1/2 x-10+10 = 0+10

1/2 x = 10

Multiply both sides by 2.

2*(1/2 x) = (2)*(10)

Your answer should be: x = 20

if x = 1, then the answer is 3.5

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
