Step-by-step explanation:
It's right on Edge! :3
We don't know the number she started with, so let's call it x.
<span>Petra started with a number added 3: x + 3
</span>
<span>multiplied the result by 4: 4(x + 3)
</span><span>subtracted 6: 4(x + 3) - 6
</span>
<span>and multiplied that result by 3: 3[4(x + 3) - 6]
</span>
her final answer was 90: <span>3[4(x + 3) - 6] = 90
Now we solve the equation for x.
</span><span>3[4(x + 3) - 6] = 90
</span>
<span>4(x + 3) - 6 = 30
4(x + 3) = 36
x + 3 = 9
x = 6
The number is 6.

X=8 which is her age
8 is her cousin age
16 is Amy's age and the sum
Is 32
Answer:
Therefore the game board is divided into 81 smaller squares.
Step-by-step explanation:
Given that, there is a square game.
Consider x be length of one side the square.
The volume of the square is = side ×side
=x² square units
Since the length of side of smaller square is one-ninth of the game board.
Then one side length of the smaller square is
units.
The area of a smaller square is 

Let a number of square is formed from the game board.
a ×The area of one smaller square= The area of game board.
According to the problem,



Therefore the game board is divided into 81 smaller squares.
