Answer:
17
Step-by-step explanation:
Let the larger number be represented by x
Let the smaller number be represented by y
from the question, the next equations can be gotten :
x - y = 9 equation 1
x = 1 + 2y equation 2
Substitute for x in equation 1
1 + 2y - y = 9
1 + y = 9
Collect like terms
y = 9 - 1
y = 8
Substitute for y in equation 1 and solve for x (the larger number)
x - 8 = 9
x = 9 + 8
x = 17
Answer:
4x+4y
Step-by-step explanation:
Only like terms can be added together so the numbers with the variable x are added together and numbers with the variable y are added together.
The expression can no longer be simplified since it has no other ways to.
Answer:
-55. just multiple -5 by 11
Answer:
1. 3212 = 3.212 X 10 of 3
2. because it easier to write and read
