36 ÷ 4 can be written as:

Thirty-six divided by four.

24 - (6 + 3) can be written as:

The difference of twenty-four and six plus three.

We'll use the expression x - 7 for this one.

The difference between a number and seven.

Hope this helps!

Solve Fast Please!!!!!!!!!!!!!! ok thanks, Bye (2x−5)^2−.5x<(2x−1)(2x+1)−15

Andrews [41]

Keep these rules in mind:

(a + b)² = a² + 2ab + b²
(a - b)² = a² - 2ab + b²
(a + b)(a - b) = a² - b²

Firstly, solve the exponent and multiplication:

$4x^2-20x+25-0.5x$

Next, combine like terms:

$4x^2-20.5x+25$

Next, subtract 4x² on both sides:

$-20.5x+25$

Next, subtract 25 on both sides:

$-20.5x$

Lastly, divide both sides by -20.5. And since you are dividing by a negative, flip the inequality sign:

$x>2$

Your answer is x > 2.

The diameter of your bicycle wheel is 34 inches. What is it’s radius

natka813 [3]

The diameter of a circle (or in this case a bicycle wheel) is how long it is from one side of the circle striaght across to the other side. The radius is half the diameter. So if the diameter is 34, then the radius would be 17.
