Monica’s school band held a car wash to raise money for a trip to a parade in new york city. after washing 125 cars, they made $775 from a combination of $5.00 quick washes and $8.00 premium washes.

let x represent the number of quick washes and let y represent the number of premium washes. which system of linear equations represents the situation?

5x + 8y = 775 and x + y =125
5x – 8y = 125 and x + y = 775
5x + 8y = 775 and x – y = 125
5x – 8y = 125 and x – y = 775

the system of linear equations that represents the situation are

5x + 8y = 775 and x + y =125

Step-by-step explanation:

Let x represent the number of quick washes and let y represent the number of premium washes.

After washing 125 cars, this means that

x + y = 125 - - -- - - - - - -1

they made $775 from a combination of $5.00 quick washes and $8.00 premium washes. This means that

5x + 8y = 775 - - - - - - -2

Equation 1 and equation 2 are the system of linear equations that represents the situation.

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72
