Answer:
the answer is D (5/3,-5/3)
Step-by-step explanation:
Answer: Infinitely many solutions
Explanation:
Let's say we had this system
y = x+5
x-y = -5
Let's replace y with x+5 in the second equation
x-y = -5
x-(y) = -5
x-(x+5) = -5
x-x-5 = -5
0x-5 = -5
0-5 = -5
-5 = -5
We end up with a true statement since we get the same number on both sides. This system has infinitely many solutions. The two equations produce the same straight line graph. Effectively, the two lines overlap perfectly to intersect infinitely many times.
Notice how solving x-y = -5 for y leads to y = x+5. This is more evidence that both original equations are identical (just in different forms).

Answer: d. 40 pounds
Step-by-step explanation: let e equal the number of pounds weigh on Earth and m equal the number of pounds weighs on Mars.
so
72m=180e
1m= 72m/72
e= 180/72 = 2.5
1m=2.5e
16m=1 x16
e= 16 x 2.5
e= 40
so therefore, 16m=40e
