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.

Answer:
<h2>Pete played 1.5 times the number of matches that Jack played.</h2><h2 />
Step-by-step explanation:
<u>Pete played 18 tennis matches in a week.</u>
P = 18
<u>Jack played 6 fewer matches than Pete. </u>
J = P - 6
J = 18 - 6
J = 12
<u>How many times the number of matches pete played is the number of matches jack played?</u>
<u />
18 / 12 = 1.5
Pete played 1.5 times the number of matches that Jack played.
1764 inches cubed. First you multiply 1.5 times 12 so that it is in inches. Then u get 18. U multiply 14 by 18 by 7 and u get 1764.
