Volume of a rectangular prism = length x width x height.
Volume of milk carton = 8 x 4 x 3 = 96 cubic inches.
Divide the volume by the leak rate:
96/ 6 = 16
It will take 16 minutes.
I believe it’s 4,-4 and 3,-3 .
Divide each number by the previous number. You always get -3.
The pattern is to multiply a number by -3 to get the next number.
The next two numbers are -243, 729
Fries are $2.50 and burgers are $4.75.
Our system of equations for this situation would be

We want the coefficients of one of the variables to be the same in order to eliminate one of them; we will make the coefficients of f the same. To do this, multiply the top equation by 5 and the bottom equation by 3:

We subtract the bottom equation:

Divide both sides by 5:
5b/5 = 23.75/5
b = 4.75
Burgers are $4.75.
Substitute this into the first equation:
4(4.75) + 3f = 26.50
19 + 3f = 26.50
Subtract 19 from both sides:
19 + 3f - 19 = 26.50 - 29
3f = 7.50
Divide both sides by 3:
3f/3 = 7.50/3
f = 2.50
O=orange
a=apple
equation 1
3o+a=$1.86
a=$1.86-3o
use a=$1.86-3o in equation 2
equation 2
2o+3a=$2.15
2o+3($1.86-3o)=$2.15
2o+$5.58-9o=$2.15
$5.58-7o=$2.15
$5.58=$2.15+7o
$3.43=7o
$0.49=o
then use $0.49=o for equation 1.
equation 1
3($0.49)+a=$1.86
$1.47+a=$1.86
a=$0.39
so an apple is $0.39.
