We will use the elimination method to solve the following system of equations. We will start by eliminating one of the variables.
1) 4x - 7y = 47 What variable can be eliminated?
6x + 7y = - 17

x = 3

y = -5

Step-by-step explanation:

It would be very easy to eliminate y by adding the two equations,

   4x - 7y = 47

   6x + 7y = -17

   10x       = 30

      x = 3                     4(3) - 7y = 47

                                   12 - 7y = 47

                                       -7y = 35

                                          y = -5

Check:  See if the values work in the second equation

6(3) + 7(-5)

= 18 - 35

= -17             It looks like they work, so we know we have the correct values

answer: 2 litters juice bottle

half of a gallon is 50% of a full gallon 2 litters of juice is 52% of a full gallon

hope this ^_^

total amount of money that he should pay if he has not used his duty free exemption is $98

step-by-step explanation:

given a united states citizen returning to the states declares the following items at the customs office: 3 shirts at $8.50 each 2 dresses at $27.50 each 1 pair of gold cuff links at $17.50 per pair. we have to find how much he pay

cost of 3 shirts if one cost at $8.50 is

cost of 2 dresses if one cost at $27.50 is  

cost of 1 pair of gold cuff at $17.50

so, total amount of money that he should pay if he has not used his duty free exemption is   $25.5+$55+$17.50=$98
