Answer:
x=-2, y=2
Step-by-step explanation:
-8x +4y=24
-7x+7y=28
substitute 4y=24+8x
y=6+2x in second equation and hence we find X=-2
put value of X in either equation and get value of y=2
Answer:
446.15
Step-by-step explanation:
C + 273.15 = K
So 173C + 273.15 = 446.15K
Answer:
B) r= c/2
Step-by-step explanation:
To isolate r, divide 2 on both sides
c = 2r
-- --
2 2
c/2=r
Hope this helps! :)
Solve for x by simplifying both sides of the equation, then isolating the variable. Answer x = −12
