Jim is 16 because take away 21-5=16.Now Cindy 21-4=17.Cindy is 17.Jim is 16.
Answer:
3y+5≤17
Step-by-step explanation:
Well we know she brought 1 note book and each note book is $5, its +5
Now we know she brought Y markers and each marker cost $3 so its 3Y
Now we know the price is no more than 17 which means she could’ve spent 17 or less tha, no more then 17 so less than or equal to sign ≤17
Now combine them
3y+5≤17
Thats the equation
If you want to find Y, solve it like an equation
The decrease is (95-68) = 27 .
As a fraction, the decrease is 27/95 of the original amount.
To change any fraction to a decimal, do the division:
(27) divided by (95) = 0.2842...
To change any decimal to a percentage, move the
decimal point two places that ==> way:
0.2842... = 28.42... %

Answer:
64
Step-by-step explanation:
49= 7*7
81=9*9
8*8=64
P=2(L+W)
60=P=2(L+W)
60=2(L+W)
divide by 2
30=L+W
given
W=-2+7L
subsitute
30=L+W
30=L-2+7L
30=8L-2
add 2
32=8L
divide by 8
4=L
sub back
W=-2+7L
W=-2+7(4)
W=-2+28
W=26
width is 26cm
length is 4cm
