Ten percent is 3 starburst because to find ten percent you divide the total number by ten. now to find 70 percent you times ten percent by seven. 3 x7 = 21 :)
Doug because his sequence follows a rule of multiplying by -1/2
Hope I got it right for your sake.
First subtract the 7 from both sides and that would equal 2x+9=2x then subtract 2x and the answer is 9
Isn't the only thing you have to do is since a cube has 6 sides than you would have to do 150 divided by 6. If I am correct.
