Answers

Answer:

4 on top three on bottom?

Step-by-step explanation:

Answer:

Hate to break it to you, but it actually is 3

Step-by-step explanation:

You need to make sure 3/4 is equal to the fraction.

It doesn't matter how many slots there are.

The fraction that it's going to be equal to is 9/12

To get the 12 on the bottom, you need to multiply the 4 by 3

Because you want to get an equivalent expression, you have to the same thing to the top.  So 3 x 3 is 9.

Both slots are going to have a 3 in it

B. 14 is your answer. Just divide 140 and 10 to find the value and that’s going to be your answer.

Answer:

D. 4

Step-by-step explanation:

Victor rides his bike the same distance to and from school each day. He also rides 3.6 miles round trip each day to go to soccer practice. During a 5-day school week, he rides a total of 43 miles. What is the round trip distance to and from school? Explain how you solved the problem.

Answers

Answer:

5 miles

Step-by-step explanation:

1. we have to figure out how many miles of the total 43 miles victor rides to and from school by subtracting the product of five days worth of soccer practice trips from the total miles per school week but that will give us one weeks worth of school trips, so we need to divide to find how long is one days worth.

2. we know victor goes to soccer and back every school day and its a 3.6 mile round trip so we have to multiply 3.6 by 5 because thats how many days are in a week which gives us 18.

3. next, we have to subtract our product (18) from our overall mileage (43) so the equation is: 43 - 18 = x (x being the trip to school and back) giving us 25.

4. the last step is we have to divide 25 by 5 because that subtraction just gave us the entire weeks' worth of biking to school and back, we just want one day. so we will divide and get 5. victor's round trip distance to and from school is 5 miles.

Simplify 3.1n - 1.1n

Answers

Answer:

2n

Step-by-step explanation:

The solution is, the value of subtraction is 2n.

What is Subtraction?

Subtraction is the process of taking away a number from another. It is a primary arithmetic operation that is denoted by a subtraction symbol (-) and is the method of calculating the difference between two numbers.

here, we have,

given expression is,

3.1n - 1.1n

we have to solve it, by subtraction.

now, we have,

3.1n - 1.1n

= (3.1 - 1.1 ) n

= 2 * n

=2n

at first, we take n common from both terms, then subtract 3.1 from 1.1, which is 2, then multiply the result 2 with n, finally we get the answer as 2n.

Hence, The solution is, the value of subtraction is 2n.
