( PLEASE HELP , TIMED ) A pet supply store sells three dog collars and two leashes for $59.75. The same pet store sells one dog collar and three leashes for $53.75. Find the cost of one dog collar and one leash.

Answers

Answer:

how can i help also comment me i wanna talk bc im lonely lol

Step-by-step explanation:

The cost of one dog collar and one dog leash are 10.25 dollars and 14.5 dollars respectively

How to form an equation?

let

the cost of each dog collars = x

the cost of each leashes = y

Therefore,

3x + 2y = 59.75

x + 3y = 53.75

Hence,

3x + 2y = 59.75

3x + 9y = 161.25

7y = 101.5

y = 101.5 / 7

y = 14.5

Therefore,

x + 3y = 53.75

x + 3(14.5) = 53.75

x = 53.75 - 43.5

x = 10.25

How many terms are in the expression when simplified

Answers

Answer:

There are four (4) different terms

Step-by-step explanation:

Given;

2x + 3xy - (x + y) + 2

The terms are simplified as follows;

=2x + 3xy - (x + y) + 2

= 2x + 3xy - x - y + 2

collect like terms;

= 2x - x  - y + 3xy + 2

= x - y + 3xy  + 2

Thus, there are four (4) different terms in the simplified expression.
