B:
Answer:
I believe 21 cm
Step-by-step explanation:
Answer:
state A = 32 votes, state B = 53 votes
Step-by-step explanation:
Let the number of electoral votes for state A be a and state B be b
a = b - 21
a + b = 85
Substituting a for b - 21 in the second equation
2b - 21 = 85
2b = 106
b = 53
Plugging b back in
85 - 53 = 32
Answer:
-3
Step-by-step explanation:
Variables are letters which are used to represent particular unknown quantities in equations.
Now the variable in this question is x.
When we talk about coefficient , we mean the number before the variable in question.
We can see that the variable is written as -3x
-3 is the value before the variable so we can agree that -3 is its coefficient
