Y = 9       x = 2
y = ?       x = 3

You can either cross multiply and you'll get 13.5
OR you can divide 2 BY 9 and you'll get 4.5 so you multiply 4.5 with 3 and you'll still get 13.5.
So both ways you'll get 13.5.

I assume you mean a direct proportion  y = kx where k is a constant
y = 9 when x == 2 so  9 = 2k  giving k = 4.5

So when x = 3,  y = 4.5x = 4.5*3 = 13.5 answer

Find the perimeter of the polygon ABCD that has its vertices at A(2, –2), B(6, –2), C(6, 6), and D(2, 6).
sergiy2304 [10]

Answer:

D. 24 Units

Step-by-step explanation:

tracing the points given we get a rectangle

the perimeter of a rectangle = 2a+2b

a=length

b= width

in this case a= 8

b= 4

the perimeter of a rectangle = (2*8)+(2*4)

the perimeter of a rectangle = 16+8

the perimeter of a rectangle = 24

a bag holds 1200 marbles colored either blue, red, green, or pink. there are 2 more blue than green, 6 more green than red and 6
krek1111 [17]
B = 2 + g . . . (1)
g = 6 + r . . . (2)
r = 6 + p . . . (3)

Putting (3) into (2) gives:
g = 6 + 6 + p = 12 + p . . . (4)
Putting (4) into (1) gives:
b = 2 + 12 + p = 14 + p . . . (5)

b + g + r + p = 1200
2 + g + 6 + r + 6 + p + p = 1200
2 + 12 + p + 6 + 6 + p + 6 + p + p = 1200
32 + 4p = 1200
4p = 1200 - 32 = 1168
p = 292

From (5), b = 14 + p = 14 + 292 = 306

Therefore, there are 306 blue mables.
