Decrease £120 by 12.5%

Mathematics
1 answer:
konstantin123 [22]3 years ago
5 0

Answer:

£ 105.

Step-by-step explanation:

Since it is required to decrease £ 120 by 12.5%, to perform this subtraction the following mathematical operation must be performed:

100 - 12.5 = 87.5

100 = 120

87.5 = X

87.5 x 120/100 = X

10,500 / 100 = X

105 = X

Thus, decreasing £ 120 by 12.5% you get a total of £ 105.

Which equation shows an example of the associative property of addition? (–4 i) 4i = –4 (i 4i) (–4 i) 4i = 4i (–4i i) 4i × (–4i
Effectus [21]

The associative property is:

A + B + C = A + (B + C) = (A + B) + C

And a option that uses this is:

-4i + i + 4i- i = (-4i + 4i) + (i - i)

<h3>Which equation shows an example of the associative property of addition?</h3>

The associative property says that we can write:

A + B + C = A + (B + C) = (A + B) + C

So, we can perform the sum in any order we want to.

Then for the given case we would have:

-4i + i + 4i- i = (-4i + 4i) + (i - i)

Where we sum in the order we want to get it equal to zero.

Answer:

16 turtles

20 frogs

32 fish

Step-by-step explanation:

let 't' = # turtles

let '4 + t' = # frogs

let '2t' = # fish

t + 4 + t + 2t = 68

4t + 4 = 68

4t = 64

t = 16 turtles

4 + 16 = 20 frogs

2(16) = 32 fish
