We can put the two equations together with substitution, and we get
3x + 2y = 30
Now we have a single equation in two variables, so we don't have enough information to solve for both x and y.
Answer:
D
Step-by-step explanation:
The rest you can elimate because of obvious inferring and reasoning so process of elimination
Answer:
=−x5+5x4+125x2−625x
Step-by-step explanation:
The answer is C
C has units of Markers / Markers on the left and Money over an unknown which represents money.
None of the others (D) is incorrect, because we've already chosen C.
A is not because.you have the wrong amount of money divided by the larger number of makers.
B does not work because the right is markers divided by money. The left had side will have money divided by markers. It won't work. The safest way to these questions up is to keep the knows on the left and put the unknown on the left with the number it is associated with.
Let's see why the others don't work.
It wouldnt be an even number but i got 7.3
