Answer:
-17
Step-by-step explanation:
add -6 + -10 which are the integers to get
-16
add -.75 + -.25 which are the decimal parts
to get -1
then you add those
to get
-17
3.5(c-8)+c = 12.5
⇒ 3.5c- 3.5*8+ c= 12.5 (distributive property)
⇒ (3.5c+ c) -28= 12.5
⇒ 4.5c= 12.5+ 28
⇒ 4.5c= 40.5
⇒ c= 40.5/ 4.5
⇒ c= 9
The correct answer is 9~
Answer:
The system of equations will have an infinite number of solutions.
Step-by-step explanation:
i) when we arrive at a solution of a linear system with two equations and two
variables and the solution of the equation does not give the value of any
variable but rather is in the form of an identity like the one given, that is
-6 = -6, then we can say that the two equations are exactly the same and
that the system of equations will have an infinite number of solutions.
