Step-by-step explanation:
simplify each equation and look for ones which solve to a simple numeric equality:
First equation solves to -3/7=-18/42...take a 6 from 18 and 42, and you get -3/7. -3/7=-3/7 which is true - that means that, no matter what value is inserted for x, a true equation will result = infinite number of solutions
Second equation simplifies to 3x=-30. Nope
Third equation simplifies to -18=-18 = infinite number of solutions
Fourth eq: 5=-7/2 = No solution
5th eq: 6.2x=-3.5-16.2 = nope
(2/3) of the box is done in (1/2) minute.
The 1 whole fraction of the box will be done in (1/2) ÷ (2/3) = 1/2 × 3/2 = 3/4 minutes
1 box is packed in (3/4) minutes.
Number of boxes per minute = (1 box) / (3/4) minute = 4/3 boxes per minute.
It’s B
2(-4)+8(4)=24
-8+32=24
-2(-4)+4=12
8+4=12
