Variables - a quantity that may change, depends on the context of the math problem. Ex: x,y
Terms - a variable, or constant, that is multiplied by a variable or variables.
Ex: 5x + 2 + 3y <-- has 3 terms
Coefficient - the constant that multiplies the variable and is next to a variable, Ex: (5x) <-- coefficient is 5
Constants - A fixed value such as 5, 6, 7, etc
1/92
what is the number we can divide both 45 and 4140 by. it is 45. divide.
45/45=1
4140/45=92
the answer is 1/92
The property is Multiplication Property of Equality.
Answer is 6(c) + 50
Step by step
We know the following
6 months cable multiplied by “c” dollars per month plus $50 one time fee
6 (c) + $50
We multiply 6 months times the unknown “c” per month. Then we add the one time fee.
The other three options multiply $50 by 6 months, by 2 and by “c”, therefore not correct.
So basically, all we have to do is change the signs when we multiply or divide by a negative so our answer is "When dividing by -8, she did not change the signs.
