30 minutes
Because it would take her an hour to go 8 miles and she is only going 4 so it is half an hour
Okay so
area of picture= 192cm
area of frame= 40×24=960
960÷ 192= 5
Therefore the picture is 1/5 of the frame.
Length of picture = 1/5 × 40 = 8cm
Width of picture = 192/8 = 24
The dimensions of the picture are then 8cm × 24 cm.
Answer:
not existing
Step-by-step explanation:
lim x goes to 0 is
so not exist
I'm not sure if u mean that or this
So
represent x for number of $14 movie tickets she got
y is number of $12 movie tickets
total of 9 tickets
x+y=9
total value is 114
14x+12y=114
we have
x+y=9
14x+12y=114
solve
multiply first equation by -12 and addd to oth equesiton
-12x-12y=-108
14x+12y=114 +
2x+0y=6
2x=6
divide 2
x=3
sub back
x+y=9
3+y=9
minus 3
y=6
3 of the $14 tickets
6 of the $12 tickets
