Answer:
B
Step-by-step explanation:
yes, we need two numbers that multiplied with each other results in -48.
that means already that one of them has to be positive and the other negative.
that gives us (with all +/- alternating sign combinations)
2 and 24
3 and 16
4 and 12
6 and 8
to pick from there we see that the "middle" term is -2x.
that means that the absolute value of the negative number has to be 2 more than the positive number (so that when adding the intermediate multiplication terms we end up with -2x).
the only choice is therefore 6 and -8.
and that makes B the right answer.
Answer:
i think its -3
Step-by-step explanation:
15 is the greatest common factor.
8x+5y=$24
6x+2y=$16.60
16x+10y=$48
-30x-10y=-$83
-14x=-$35
x=$2.50
8($2.50)+5y=$24
$20.00+5y=$24
5y=$4
y=$0.80
Hamburgers costs $2.50 each
Fries cost $0.80 each
