Answer:
20%
Step-by-step explanation:
So, I would set this up as a proportion-
72 x
90 100
Cross multiply-
100 x 72 = 7200
Divide-
7200/90 = 80
Subtract-
100 - 80 = 20
So, it is a 20% decrease
Answer:
y = 7
Step-by-step explanation:
5(3y - 13) = 6y - 2
5*3y + 5*-13 = 6y - 2
15y - 65 = 6y - 2
15y - 6y = 65 - 2
9y = 63
y = 63/9
y = 7
Check:
5((3*7)-13) = 6*7 - 2
5(21-13) = 42 - 2
5*8 = 40
Answer:
Prime
Step-by-step explanation:
If we have a point on a pre-image, we can have it labelled as A(x,y)
Now, we can write this as the image
To write this as the image, we simply have to add a mark on the A
This mark is at the upper right
We have it as A’ (x,y)
The part added is called a prime
