x+y-z+w = 10--------(1)
x+3y-4z+5w=26------(2)
x+4y-7z+7w = 37-------(3)
x+2y-3z+6w = 22--------(4)
Subtract equation (1) from (2)
x+3y-4z+5w - (x+y-z+w) = 26 - 10
2y + -3z - 4w = 16-----------------------------(5)
Subtract equation (1) from (3)
Answer:
x>10
Step-by-step explanation:
more than 10!!!
10.0000000000000000000001-2=8.0000000000000000000001
more than 8!!!
This is a scalene triangle, as it has 3 unequal sides
Answer:
40n
Step-by-step explanation:
(40+n): The first one is asking to add forty and n, however the question is asking for multiplication so that is not an answer.
(n-40): This one is using subtraction, so this one is an obvious no.
(40/n): This phrase represents division, this could be a possibility because it is the inverse operation, however the numbers need to be reversed.
(40n): Im thinking that you got confused because there was no operation symbol. Whenever a number and a variable are attached without an operation symbol in between, you multiply. So, this is the correct answer.
Answer:
Step-by-step explanation:
