Answer:
Step-by-step explanation:
EF = CD
FC = DE These equal lines are properties of a parallelogram.
2y = 3y - 17 Add 17 to both sides
2y + 17 = 3y Subtract 2y from both sides.
2y-2y+17 =3y-2y
y = 17
CD = y + 43
CD = 17+43
CD = 60
Since CD = 60 then FE = 60
Answer:
rise is 11 and run is 2
Step-by-step explanation:
i believe but not fully sure
Area=lengthxwidth
9*6=54
Perimiter=l+w+l+w
6+9+6+9=30
The way we would answer the question would be to express it as
100-9(n-1) with n being the nth term of the pattern.
Why is this? We know we subtract 9 each time and START from 100.
Remember though that 100 is the first term in the sequence. So, we would have (n-1)*9 to subtract 0 from our 1st term and 9 from our second term.
Also, we have 9*(n-1) because we are just subtracting multiples of 9. It is always going to subtract by 9.
If you needed the answer here it is...
The answer to the problem would be
100-9(13-1)
= 100-9(12)
= 100-108
= -8
2a+3b=82
a+b=38
These are the two equations you need to solve for a and b
