You have to follow the rule P.E.M.D.A.S.
So first since there are no parenthesis (P.) or exponents (E.) you have to either multiply (M.) or divide (D.) .
So first you do 6 / 2 which equals 3.
Replace 6/2 in the equation with 3.
54 - 3 + 6
Then you have to either add (A.) or subtract (S.)
So 54 - 3 = 51 + 6 = 57

Ps. To remember P.E.M.D.A.S a phrase I was taught in middle school was "Please excuse my dear aunt sally." It makes remembering the order much easier.

You would use, Order of Operations, A.K.A PEMDAS.
Parenthesis, Exponets, Multiplication, Division, Addition, Subtraction
Follow that order and you do the work yourself, you would never learn by asking other's for the answer. >:)

A rectangular computer table measures 30 inches by 50 inches. We need to cover it with square tiles. What is the side length of

jekas [21]

Answer:

a) 10*10 inch, b)yes, c) 15

Step-by-step explanation:

we need to calculate the Greatest Common Factor between 30 and 50

$30 = 2 \times 3 \times 5 \\ 50 = 2 \times 5 \times 5 \\ GCM = 2 \times 5 = 10$

then, the square tiles will be 10 inch *10 inch

b) it will change because they don't need to have the largest slab possible so they will use any other comon factor with a size they consider correct for the cheese.

$30 \div 10 = 3 \\ 50 \div 10 = 5 \\ 3 \times 5 = 15$
