A retired math teacher takes her niece shopping. She tells her niece that they can spend x dollars and 19x = 1326.2. What operation does the niece need to use to find how much money they can spend?
Choose the correct answer below.
O Addition
O Subtraction
O Division
O Multiplication

Division. The niece can divide both sides of the equation by 19 to find the answer.

Let me know if this helps!

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
