Answer:
You would divide 132 by 3 to get the unit rate of 44 mph. Then multiply by 4 to get 176 miles in 4 hours
Step-by-step explanation:
For this case, we must find the quotient of
divided by
, to verify if Tina was correct.
So:

So, Tina was wrong, she had to divide by 3x.
Answer:
Option B
Well, this is absolute value, so as a mixed fraction you would have to times the denominator to the whole number, and then add the answer of that to the numerator (2 x 2 x 1). After that, you should get a whole number as an answer, but make it as a fraction. (put the whole number you got on top of the denominator before (2) to make it a fraction). Then, again, since it's absolute value, then it into a negative. Hope this helps and hope it not confusing!!
You have to do 45 divided by 2. Hopefully there is not tax!
Answer:
y=1; x=2
Step-by-step explanation:
Substitution:
x=2y
2x+5y=9
=> if x=2y, plug in the x value into other equation, so
----------------------------------------------------------------------------
2(2y)+5y=9
4y+5y=9
9y=9
y=1
You have the Y value, so now solve for X
-----------------------------------------------------------------------
plug in y value to x=2y
so x=2(1)
x=2
