Use addition to show how to find 16-9

2 answers:

8 0

Equation : 9 + x = 16

9 - 9 + x = 16 - 9
X = 7

4 0

It would be 9 + x =16
To solve it, subtract 9 from both sides of the equal sign
So (9+x)-9=16-9
Which is x=7, so the answer is 7.

Answer:

96.8 percent

Step-by-step explanation:

You can cut off two zeros from both numbers to compare 1000 to 32.

The difference is 968, and the original is 1000.

So you divide 968 by 1000 to get 0.968 which is equal to 96.8 percent.

$(f\circ f)(x)=f(f(x))\\\\ (f\circ f)(x)=x^2\Longleftrightarrow f(f(x))=x^2\\\\ f(f(f(f(f(f(2))))))=f(f(f(f(4))))=f(f(16))=256$
