Answer:
The value of y = 7.5 and the scale factor is 2/3.
Step-by-step explanation:
To get the scale factor, let's get the ratio of 17 to 25
To check if 17 really is the 2/3 of 25.5
Therefore, if 17 is the 2/3 of 25.5, then the line (3y-3.5) is also the 2/3 of (3y+6).
Answer:
29
Step-by-step explanation:
because 29 for the 4 = 7 for 8
X+y=217. x+y=217
x-y=85. 151+y=217
-----------. y=217-151
2x=302. y=66
x=151
