Answer:
a)
Step-by-step explanation:
note that the shaded dot means that it's either a greater than or equal to sign or a less than or equal to sign
but when it's not shaded it's means it's simply a greater than or less than sign
so
m+3<10
carry the 3 over the < sign
this will make the 3 become negative
m<10-3
now subtract
m<7
