Answer:
23.32
Step-by-step explanation:
the hundredths place is the 2 spot after the decimal
and if the # to the right of that # is 5 or grater you add a one
if it is 4 or lower you keep the # the same
23.3238
because 3 is next to the second place the 2 just stays the same
so now it's
23.32
Step-by-step explanation:
it can be 700 + 36
hope it helps...
P=38
P=2x+2y=2(x+y)
x=9+y
so
38=P=2(x+y)
38=2(x+y)
divide both sides by 2
19=x+y
x=9+y
19=9+y+y
19=9+2y
minus 9 both sides
10=2y
divide by 2
5=y
sub back
x=9+y
x=9+5
x=14
x=14
y=5
