Answer:
D. -5
Step-by-step explanation:

The compound fraction is easily simplified because both numerator and denominator have 5 in their denominator. Hence the ratio is the ratio of the numerators.
When an odd number of minus signs is involved in multiplication or division, the result is negative.
You can either use a caculator or use pencil and paper if you know how to times the numbers line them up then time it ill show you
do 20 divide 5/4 (=1 1/4)
so 20 * 4/5 which would be 80/5; simplifies to 16 cans
Answer:
the first answer ( I think these are 3 different questions) is y = -4x + 7
the second answer is y = -3x + 5
the third answer is y = 6x - 5, because the lines are parallel, they have the same slope and the y int is -5 from the point given.
