Answer:
64 ivy stems
Step-by-step explanation:
To solve this problem we can use rule of three:
Firstly we had 72 ivy stems to use in 18 centerpieces, and know we have 16 centerpieces and want to know how many ivy stems we need to use, so:
18 centerpieces -> 72 ivy stems
16 centerpieces -> X ivy stems
18/16 = 72/X
X = 16*72/18 = 64
He needs to use now 64 ivy stems to maintain the ratio.

Answer:
y = 1/5x -2
Step-by-step explanation:
When a point and slope are given, sometimes it is easiest to start with the point-slope form of the equation. Then it can be rearranged to the desired form.
y -k = m(x -h) . . . . . line with slope m through point (h, k)
y -0 = 1/5(x -10) . . . . . line with slope 1/5 through point (10, 0)
y = 1/5x -2 . . . . . . . eliminate parentheses to get slope-intercept form
_____
Note that the slope in the attached picture is 1/5, but your problem text says it is 5. Very different equations will result from these different slopes.
16^x / 4^x
= 4^2x / 4^x
= 4^x so E is one choice.
also C and D
Let 
be the legs of the triangle, with ![x[tex]\mathrm{area}_{\rm square} = y^2](https://tex.z-dn.net/?f=x%5Btex%5D%5Cmathrm%7Barea%7D_%7B%5Crm%20square%7D%20%3D%20y%5E2)
The square has 3 times the area of the triangle, so
Meanwhile, in the triangle we have
Now,
