Kenya has 2 hours to make a 104 mile trip. What rate must she average to make the trip in 2 hours?
Responses
A 50 mph50 mph
B 51 mph51 mph
C 52 mph52 mph
D 53 mph
To find the rate Kenya must average to make the trip in 2 hours, we divide the distance by the time:
Rate = Distance / Time
Rate = 104 miles / 2 hours
Rate = 52 mph
Therefore, the rate Kenya must average to make the trip in 2 hours is C. 52 mph.

Which equation represents the data in the table shown?
Responses
A y = −2xy = −2x
B y = 2x + 3y = 2x + 3
C y = −2x + 3y = −2x + 3
D y = −2x − 3y = −2x − 3
E y = −4x − 3
To find the equation that represents the data in the table, we need to look for a relationship between x and y. We can see that as x increases by 1, y decreases by 2. Therefore, the equation that represents the data is a linear equation with a negative slope.
Among the given options, the equation that fits this relationship is D. y = -2x - 3. As x increases by 1, y decreases by 2 and we can confirm this by plugging in the values from the table.
Each issue of Soccer World magazine costs $5.99 at the book store. A 6-month subscription costs $24.99. How much can a reader save by subscribing to the magazine for 6 months?
Responses
A $10.95$10.95
B $11.95$11.95
C $19.00$19.00
D $8.95$8.95
E $9.99
To calculate the savings by subscribing for 6 months, we need to find the difference between the total cost of buying each issue individually and the cost of the subscription.
The cost of buying each issue individually for 6 months would be: $5.99 * 6 = $35.94.
Therefore, the savings by subscribing for 6 months is: $35.94 - $24.99 = $10.95.
The correct answer is A. $10.95.
