Answer:

  x = 18

Step-by-step explanation:

Vertical angles are equal

So

3x+20 = 5x-16

3x - 5x = -16 - 20

-2x = -36

  x = 18

When a number is decreased by 7.3%, the result is 60. What is the original number to
marishachu [46]

Answer:

Original Number = let we assume it is x

Number after decremented =  y = 60

Total decrease = z = x-y = x-60

% of decrease = ((x-60)/x)*100 = 7.3

(x-60)*100 = 7.3x

100x -6000 = 7.3x

100x-7.3x = 6000

92.7x = 6000

x = 6000/92.7 = 64.73

Original Number = 64.73

Unless you just want to give money to the ice cream truck, for 0 items, you will pay 0.

Since the price of each item is $0.77, for one item you will pay $0.77. (Is that a surprise?)

Then for two items, you will pay $0.77 for each one, or $0.77 + 0.77 = $1.54. You can also compute this by making use of the fact that multiplication is a shortcut for repeated addition. The price can be found by $0.77×2 = $1.54 = f(2).

Similarly, for 3 items, you can add $0.77 three times: $0.77 + 0.77 + 0.77 = f(3), or you can use multiplication: $0.77×3 = $2.31 = f(3).

a) Our table looks like
  (x, f(x))
  (0, 0)
  (1, 0.77)
  (2, 1.54)
  (3, 2.31)

b) By now, I'm sure you have realized that to find the price of x items, you multiply 0.77 by x.
  f(x) = 0.77x
