The answer on E2020 is A: Rolling a six-sided number cube 24 times and recording if a 4 comes up.
4.4a-7.3 is equal to
4.4a= 7.3 divide both sides by 4.4
a= 1.66
I think the answer is 2( 4x+3)(x-2)
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.
Use proportion, so multiply 100 by 75, then divide it by 30 and that's your answer.....250
