Answer:
y+2m(m) (x+1+2) ???
Step-by-step explanation:
17
but it can be 18 too
cuz the q doesn't tell us that the value of x has to be a prime no.
2+3+5+7+11+13+17=58
5 9/14
7 1/2
a) 4 1/7 + 1 1/2= 4+ 1/7 +1 +1/2 = 5 + 1/7 +1/2 = 5+ 2/14 + 7/14= 5 + 9/14= 5 9/14
b) 4 1/2 ÷ 3/5 = 9/2 ÷ 3/5 = 9/2 *5/3= 3/2*5= 15/2= 7 1/2
Does the answer help you?
