Y would be 81 because 9x9
X would be 16...
If the question is 81-16 then it equals 65
Answer:
0.3 or 3/10
Step-by-step explanation:
If
= 6, then p must be 0.5 (since 3/[1/2] is also 3x2).
If
= 15, then q must be 0.2 (since 3/[1/5] is also 3x5).
p - q would be 0.5 - 0.2, which means the final answer is 0.3 (3/10).
Answer: x=25.6
Step-by-step explanation:Look at pic to see how it is solved.
Times 6.4 on both sides which gives you 25.6 .
Answer:
Step-by-step explanation:
x+y>0, x>0, when y=0
x+y<-5 x<-5 when y=0
since the sign is only< then it is dotted line, and since one is greater and is less than they actually do not intersect
Answer:
3) 124
Step-by-step explanation:
a1 = 10
a2 = a1+6 = 10+6 = 16
a3 = a2+6 = a1+6+6 = a1 + 2×6 = 22
a4 = a3+6 = a2+6+6 = a1+6+6+6 = a1 + 3×6 = 28
...
=>
an = an-1 + 6 = a1 + 6(n-1)
=>
a20 = a1 + 6(20-1) = 10 + 6×19 = 10+114 = 124
