Answer:
C = 1.5m+6
Step-by-step explanation:
The numbers of miles that we ride, we are charged 1.5 based on that. Hence, 1.5m. And we are anyway charged with 6 dollars, so plus 6.
Answer:
not necessarily
Step-by-step explanation:
Taking the square root of both sides, you have ...
±a = ±b
Those four cases resolve to two unique cases:
a = ±b
The given equation will be true if a = b or if a = -b. If a and b are constrained to have the same sign, then a=b is the only solution.
Answer:
8 - (3 x 2) - (1 + 1) = 0
or
8 - 3 x 2 - (1 + 1) = 0
Remember PEMDAS.
If I put parenthesis around 3 x 2, I get 6.
But 8 - 6 = 2
How can we make 2 - 1 + 1 = 0?
If we look at PEMDAS, we know (2 - 1) + 1 = 2, but the answer needs to be 0.
So now try 2 - (1 + 1) and that gives me 0.
And it says parentheses...but you can also do 8 - 3 x 2 - (1 + 1) = 0.
