Pretend to (or actually) cut out the given image, stick a pin in point P so it cannot move, and rotate the cutout up and to the left around point P about 1/8 of the way around the circle. The result of doing that is the picture you're looking for.
The given statement written in symbolic language is x = 3y + 4 and x + y = 72 where "x" is the cost of one book and "y" is the cost of another book
<em><u>Solution:</u></em>
Given that Bruce bought two books
One book costs $ 4.00 more than three times the other
Let the two books be denoted as Book A and book B
Let "x" be the cost of book A
Let "y" be the cost of Book B
From given,
One book costs $ 4.00 more than three times the other
Let Cost of book A = $ 4.00 more than three times the other book B
x = 4 + 3 times cost of Book B
x = 4 + 3y
x = 3y + 4 --- (i)
Also given that Together, the two books cost him $72
cost of book A + cost of Book B = 72
x + y = 72 ------- (ii)
Therefore the given statement written in symbolic language is:
x = 3y + 4 and x + y = 72
For the first movie he has 6 choices, then for the second since he has chosen the first there are only 5 left, then for the third there are only 4 choices left and so on.
Therefore the answer is 6!=6*5*4*3*2=720 orderings
Answer:
The 40th number in the pattern is 9.
because it repeats every 4 numbers, so you just can change this pattern into normal, like 1 2 3 4 ... and just count, or you can just divide every number given in the choices by four
