Answer:
Peter is 20 now
Step-by-step explanation:
Now
P = A +5 and J = 2P
plug in P in J = 2P = 2(A+5) =2A +10
In 5 years
J+5 = 3A
2A+10+5 = 3A
2A + 15 = 3A subtract 2A from each side
A = 15 so Alice is 15 now
P = A+5 =15+5= 20 so Peter is 20 now
Let's check :
P=20 J=40 A=15
in 5 years J = 45 A =3*15=45
Okay, so the first thing we have to do is take 6ft and convert it into inches so we get the equation (6x12)+6 6 times 12 is 72 so that gives us 72in plus 6 which is 78 and with that answer we take 78in and divide it by 6.17 which is 12.18. She has a long arm measuring i while feet and 18 inches lol
33: 21 ...........................................
The answer is 2 1/4 so the answer is D all you have to do is look at how he says 3/4 to make 12 so 12 times 3 is 36 than you just do 3/4 times 3 and you get your answer.
Hope this is helpful :)
