11. Assuming distance is proportional to time,
.. (3 h)/(7 h) = d/(665 km)
.. d = (665 km)*(3/7) = 285 km . . . . . . selection B
12. (30 L)/(1.5 L/min) = 20 min . . . . . . selection C
These cannot make any types of triangles.
Kind of hard to tell what’s a plus and minus sign so maybe some of these are incorrect.
The first one says x+2x+4y.
So the first thing you would do is combine like terms.
x and 2x are like terms.
Since x has no number you would have to put a 1 in place for it.
So you would have 1x+2x which would be 3x.
You would then put that together and have 3x+4y.
1,000,000 this might be the answer
