Answer:
A is the answer.
Step-by-step explanation:
What you do is you multiply -6 into each of the fractions and then add or minus the fractions together.
-6(1/4x)=-3/2x
-6(-2/3x)=4x
-6(5/6x)=-5x
-3/4x+4x-5x=-2.5 or A.
I’m pretty sure it’s 9, I haven’t done this in awhile though...
548800.
Use the fundamental counting principle and combinations formula to find the total possibilities. use combinations to find the combos then multiply each set of possibilities together.
7 nCr 3 = 35 hamburgers combo possibilities.
5 nCr 2 = 10 sides combo possibilities
8 nCr 3 = 56 drinks combo possibilities
8 nCr 2 = 28 ice cream combo possibilities
Multiply each possibility together to get total possibilities.
35*10*56*28 = 548800
