Not all people like football there just boys jumping on eachother but some people like that
A
a) y+6x=5 if x= -1 then y+6(-1)=5 then y = 11
b) same thing if x = 3 then y+6(3)=5 y+18=5 subtract both sides by -18 and leave y on left then add 5+(-18)= 13 then y=13
B same as above
question (a) asks you to solve for y because x is -2
(b) asks you to solve for x because y is known
3x+2y=-6 if y = 3 you write 3x+2(3)=-6 3x+6=-6 move the +6 over to right side by subtracting 6 from both side 3x=-6 + -6 so 3x=-12 to get rid of the 3 and only leave the x you want to divide both side by 3 then x= -12/3 then the answer would be x=-4
So multiply 2 x 1.10 = 2.20
3 x 95 = 2.85
5 x 2.15 = 10.75
Now add all that up 15.80 divide 15.80 by 5 to get 3 dollars and 16 cents(thats how much everyone pays)
or if your going to include tracy to the 5 people which would make 6 it would be 2.63333333333 so round that up to either 2.60 or 2.63
The answer is going to be C.)
