Answer:
y = 0
x = 8
Step-by-step explanation:
subtract second equation from first one
3x - 6y - (3x - y) = 24 - 24 the - sign in front of the parenthesis effects the inside expressions
3x - 6y - 3x + y = 24 - 24 add/subtract like terms
-5y = 0 and so y = 0
to find the value of x we can use this information
3x - y = 24 since y = 0
3x = 24 divide both sides by 3
x = 8
Answer:
-28m-12
Step-by-step explanation:hope that helps :)
=(−4)(3+7m)
=(−4)(3)+(−4)(7m)

Answer:
-0.5°C every hour
Step-by-step explanation:as the temperature of the bottom of the mountain changed at 1/5 the rate of temperatures change on the top of the mountain, so, the hourly rate of temperature change at the bottom of the mountain is=
-2.5×(1/5)
=-0.5
