Average speed = total miles driven / total driving time
average speed = (150 + 100) / (3 + 1 1/2) =
250 / (4 1/2) =
250 / (9/2) =
250 * 2/9 =
500 / 9 = 55.55 mph
Answer:
Step-by-step explanation:
y = –⁷⁄₉x + 5
+ ⁷⁄₉x + ⁷⁄₉x
___________
⁷⁄₉x + y = 5 [We CANNOT leave the equation like this, so multiply by 9 to eradicate the fraction.]
9[⁷⁄₉x + y = 5]

Answer:
$2.50 can be your constant because you will have to pay it once in order to bowl. $2.25 can be the coefficient of the variable. You can form the equation now. y is total price while x is how many games you can bowl.
Now that you have the equation, you can solve. Knowing that you have $9.25, just plug in that value in the y
Now, just simply solve for x and you will find the answer to the second part of the question. You will get x=3
