the following equation has been solved incorrectly. Explain the students error
Kate is going to the fair with three of her friends. It will cost $5.00 to get in and an additional $2 per ride. Create an equation to represent the cost for the whole group and then use the distributive property to expand the expression and solve the problem.
Expression: (4*5)+(2*5)=30
So I have the expression I just need to do the distributive property and I don't understand how to do that.
Answer:
5 * ( 4 + 2 ) = 5 * 6 = 30
Step-by-step explanation:
(5*4) + (2*5) = 20 + 10 = 30
5*4 = 4 people need to pay $5
2*5 = $2 for 5 rides
Distributive Property:
(5*4) + (2*5) = 5 * ( 4 + 2 )
5 * ( 4 + 2 ) = 5 * 6 = 30
Answer:
$40Step-by-step explanation:
Ok, so the distributive property allows us to apply a number evenly over a whole set of numbers.
Equation: 4 (2 x 5) (we distribute the 4 to all terms, since each person experiences those charges.) The answer is $40 for the whole group.

Over the course of a year, a tractor-trailer commutes 160,000 miles across America.
a. Assuming a trucker changes his tires every 40,000 miles, and that he starts with a brand new set of tires, how many sets of tires will he use in a year?
b. If the trucker changes the oil every 10,000 miles, and he starts the year with a fresh oil change, how many times will he change the oil in a year?
Answer:
a. 4 sets of tires in a year.
b. 17 times a year.
Step-by-step explanation:
a. I just divided 160,000 by 40,000 to get 4 sets a year.
b. I divided 160,000 by 10,000 and then added 1 to get 17 times a year. I added one because the problem said that the trucker changes the oil in the beginning of the year.

Step-by-step explanation:
The Farmers Market sells apples by the bushel, and each bushel of apples weighs 42 lbs. A bushel of large apples contains 84 apples. If a bushel of small apples contains twice as many apples as a bushel of large apples, how many small apples are in 1 lb. of small apples? It’s says show work
Answer: 4 apples in 1 lb
Step-by-step explanation: There are twice as many small apples as large apples, so multiply 2 × 84 = 168
to find apples per pound, divide the total number of apples, 168, by the weight of the bushel: 42 lbs.
168 /42 = 4 apples/lb
The required number of small apples in one pound is 4.
Given that,
Each bushel of apples weighs 42 lbs. A bushel of large apples contains 84 apples. If a bushel of small apples contains twice as many apples as a bushel of large apples, how many small apples are in 1 lb. of small apples, is to be determined.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
Large apples in 1 pound = 84 / 42 = 2
Now, according to the question,
Number of small apples = 2 (number of large apples)
Number of small apples = 2 (2)
Number of small apples = 4
Thus, the required number of small apples in one pound is 4.
