Hello! :)
Use a proportion to find how many seconds are needed to fold 5 shirts.
We are given that he takes 28 seconds to fold 2 shirts:
28 sec : 2 shirts
We are not given the amount of time needed for 5 shirts, which we need to solve:
x seconds : 5 shirts
Express in a fraction:
Cross multiply and simplify:
Therefore, he needs 70 seconds to fold 5 shirts.
1 - 3
2 - 3
3 - C
4 - D
5 - C
For this, you multiply the 12 two point shots she made to see how many points she earned
12 x 2 = 24
now you will subtract the 24 from 27 to find out how many points are left
27 - 24 = 3
this means she made 12 two point shots (worth 24 points) and 1 three point shot (worth 3 points) to total up as her 27 points:)
Y = x² - 8x + 29
y = (x² -8x +4²) + 29 -4² . . . . add and subtract the square of half the x-coefficient
y = (x -4)² + 13 . . . . . . . . . . . . simplify
The appropriate choice is
C. y = (x - 4)² + 13
