Step-by-step explanation:
2.4 (-1/2)
=2.4×(-0.5)
=-1/2
The answer is 277. If you use PEMDAS you would multiply 9x27. Then 2x31. Then add them 243+62. Then subtract 28. Which gives you 277
5y = 2x.....y = (2/5)x
y = (2/5)x
10y = 4x.....y = 4/10x....y = (2/5)x
5xy = 2....y = 2/(5x) <==== this does not belong because it is not a linear equation like the rest of them are.
