How does the order of operations help solve one and two step equations

The order of operations, or PEMDAS (Parenthesis, Exponents, Multiplication, Division, Addition, and Subtraction.

If there are any parenthesis, solve what is in the parenthesis first. For each step in the order of operations, if there are multiple; for example multiple numbers to multiply, you would start with the one most left and then move towards the right.

After parenthesis, solve for any exponents(squared, cubed, or a number to a power).

Then going left to right, multiply and divide any numbers together that need multiplied or divided.
Then add and subtract.
You should then have your answer

If you go from right to left, or left to right, you won't get the right answers. By using order of operations, you will get a more accurate and correct answer.

Hope this helps :)

4 friends evenly divided up a n- slice pizza. One of the friends , Harris, ate 1 fewer slice than he received. How many slices o

LenKa [72]

4 friends evenly dividing up a n - slice pizza

So each one get $\frac{n}{4}$ slices of pizza.

For example, if n = 12 slice then each friend gets 12/4 = 3 pieces. If Harris ate one slice less then he ate $\frac{12}{4}-1$ =3 -1 = 2 pieces.

So the general expression for slices of pizza did Harris eat is

$\frac{n}{4}-1$

A square has a diagonal length of 10 ft. Draw a diagram and determine the perimeter of the square.

denpristay [2]

The perimeter of the square is: $20\sqrt2$ ft

Step-by-step explanation:

The picture is attached with the answer.

the diagonal of a square divides it into two right angled-triangles.

We can use one of the triangle to find the length of side as the diagonal will be the hypotenuse of the triangle

Let a be the side of the square, then according to Pythagoras theorem

$d^2=a^2+a^2\\(10)^2 = 2a^2\\2a^2=100$

Dividing both sides by 2

$\frac{2a^2}{2}=\frac{100}{2}\\a^2=50$

Taking Square root on both sides

$\sqrt{a^2}=\sqrt{50}\\a=\sqrt{25*2}\\a=\sqrt{5^2 * 2}\\a=5\sqrt{2}\ ft$

Now,

$P = 4a\\P = 4 * 5\sqrt{2}\\=20\sqrt{2}\ ft$

Hence,

The perimeter of the square is: $20\sqrt2$ ft

Find the inverse of the function f(x) = (x - 4) 2 - 5 if x ≥ 4.

Serggg [28]

Same here, we do a quick switcharoo on the variables first,

$\bf \stackrel{f(x)}{y}=(x-4)^2-5\qquad inverse\implies \boxed{x}=\left( \boxed{y}-4 \right)^2-5
\\\\\\
x+5=(y-4)^2\implies \pm\sqrt{x+5}=y-4\implies \pm\sqrt{x+5}+4=y$
