Answer:
Hey there! your answer should be the first choice, -1/8
Step-by-step explanation:
multiplication and division in fraction are way easier than adding and subtracting them since you don't have to use factoring much.
so first you set them aside
then, literally just multiply them across.
meaning, top times top a.k.a. the numerator and bottom times bottom a.k.a. the denominator
check this little cheat code
positive x positive = positive
negative x negative = positive
positive x negative = negative
negative x positive = negative
so lets do the top, the numerators first: 1 x (-1) = -1
then the bottom, the denominators next: 2 x 4 = 8
now replace your answer with that and you get which leads you with the first answer choice.
I hope this helps! :)

Answer:
a. The student's conclusion is incorrect because the solution to the system of equations 3x + 4y = 32 and 5x + 5y = 50 is (8, 2).
Step-by-step explanation:
The second equation needs to be ...
5x +5y = 50
because the wording "short of $18" means that the actual cost of that purchase would be $18 more than the $32 that Harry had. 18+32 = 50.
The only answer choice that shows this as the second equation is choice A.

In fact, the solution to the system of equations is (8, 2), as can be seen in the graph below.
