Each month, kaisorn deposits $50.00 onto her public transportation card. it costs her $2.50 per trip to ride the subway. thom deposits $40.00 on his public transportation card. it costs him $2.00 per trip to ride the subway. if x represents the number of trips and y represents the amount remaining in each account, which system of equations represents their transportation costs? 50 − 2.5x = y 40 − 2x = y 50 + 2.5x = y 40 + 2x = y 50 − 2.5y = x 40 − 2y = x 50 + 2.5y = x 40 + 2y = x

For Kaisorn:

For Thom:

Step-by-step explanation:

Each month, Kaisorn deposits $50.00 onto her public transportation card.

It costs her $2.50 per trip to ride the subway. Means 2.50x

Thom deposits $40.00 on his public transportation card. It costs him $2.00 per trip to ride the subway. Means 2x

Let x represents the number of trips

Let y represents the amount remaining in each account.

Then the system of equations represents their transportation costs are :

For Kaisorn:

For Thom:

answer: 457.14

step-by-step explanation:

205 - 45 = 160

160 / .35 = 457.142857

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
