The question is probably incomplete. What i am assuming is that the person might ask for the previous ratio or the total number of pens and pencil in the drawer.
So if it is the previous ratio it obviously would be 47 - 5 : 17 -3 so 42 : 14 and in case he or she is asking for the total number of pens and pencils in the drawer before so they were 42 + 14 hence 56.
Answer:
Step-by-step explanation:
For 
, we have two cases:
Using this, we can solve all four of the problems:
Answer:x=+3/7 or x=-3/7
Step-by-step explanation:
49x^2=9
Divide both sides by 49
49x^2 ➗ 49=9 ➗ 49
x^2=9/49
Taking the square root of both sides we get
x=±√(9/49)
x=±(3/7)
x=+3/7 or x=-3/7
H(arold) = 2 + 2*K(enneth)
H = 2 + 2K
H + K = 38
Substitution:
2 + 2K + K = 38
3K = 36
K = 12
Kenneth solved 12 problems and Harold solved (2(12) + 2 = 24 + 2 =) 26 problems
Pretty sure it would be 21x^2+16x+17y
