Times 11 by 30 and 6 by x. You should get 6x=330. then divide 6 by 330 and you'll get 55. x=55<span />
The pattern they're looking for in the uppermost question is 0,2,6,14,30,62.
The second problem shows the Fibonacci sequence. Each number is the sum of the two numbers before it. So:
2,3,5,8,13,21,34
34 are the number of miles she'll run on Week 8.
The equation on the bottom right is M = 5p. The first two numbers in the function table are 25 and 50.
I find it easiest to subtract and add the percentages to make a multiplier, then use that.
After the man's discount, he pays (100% - 12%) = 88% of the list price. After tax, he pays (100% + 3%) = 103% of the discounted price.
The amount he actually pays is $255×0.88×1.03 = $231.13.
The best choice is ...
(B) $231.13
Eliminate parenthesis by using the distribution property
= 5x² -3x +3 - x² - 2x +1
Group similar terms
= (5-1)*x² + (-3 -2)*x + (3+1)
Then sum everything:
= 4x² -5x +4
Well the LCM (lowest common multiples) for 8 and 32 would be 4. So plug 4 into "b" -8×4-32. -8×4=32. -32-32. Since you can't subtract 32 and 32 you add! Which gives you -64.
Hope this helps (:
