The expressions in the table represent how far two friends rode their bicycles on a bike trail.
Javier : 5n + 1
Aisha : 3n + 4
Write an expression that shows the difference between the miles ridden by Javier and the miles ridden by Aisha.
Part B If n = 2, how many more miles did Javier ride than Aisha?

Answer:

a. the first and last one

b. the second and third one

Step-by-step explanation:

a. 11x-3x-10x=18x, so the first one is definitely the answer. If you look at the last one, you can see that 10x+8x also equals 18x. The other options do not equal 18x, so those can be eliminated.

b. If you distribute the 3 outside of the parentheses, you can see that the expression 3(1+3y) equals 3+9y (because 3*1=3 and 3*3y=9y). So, the third one can be determined to be one of the answers. We can see that the second one also simplifies to be 3+9y, so this one can also be determined to be the answer. The other ones can be eliminated because they do not equal 3+9y.

Hope this helped! :)

Answer:

a) 18x and 8x + 10x

b) 3 × 1 + 3 × 3y and 3 + 9y

Step-by-step explanation:

11x - 3x = 8x and then 8x + 10x is left. The answers are 18x and 8x + 10x.

3 × 1 is 3 and 3y × 3 is 9y.

Answer:

-3

Step-by-step explanation:

5(y+2/5)=-13

5(y+0.4)

5y + 2 =-13

5y=-13+2

5y=-15

y=-15/5

y=-3

5(-3+2/5)=-13

Answer:

3.375 miles

Step-by-step explanation:

A runner runs at a rate of 4.5 miles per hour. How far does the runner run in 0.75 hours?

x = hours they ran

4.5x <== substitute 0.75 for x

4.5(0.75) <== multiply

3.375 miles

The volume of prism is,

⇒ V = 126 yards²

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

A right prism has a triangular base. The length of the base is 12 yards and the height of the base is 3 yards. The height of the prism is 3.5 yards.

We know that;

The volume of prism is,

⇒ V = B × H

Where,  B is the area of the base and h is the height of the prism.

Hence, We get;

The volume of prism is,

⇒ V = 12 × 3 × 3.5

⇒ V = 126 yards²

Thus, The volume of prism is,

⇒ V = 126 yards²

The complete table is given below.

2. 3 miles per hour, 2.75 miles per hour, and 3.5 miles per hour are the speed of Diego, Elena, and Andre respectively.

3. To reach one mile: 0.33 hours, 0.36 hours, and 0.29 hours are the required time for Diego, Elena, and Andre respectively.

Velocity is the pace and direction of an item's movement, whereas speed is the time rate at which an object is traveling along a route.

Given:

Diego, Elena, and Andre participated in a walk-a-thon to raise money for cancer research.

They each walked at a constant rate, but their rates were different.

Answer:

A: 4

Step-by-step explanation:

So first you can move the 2^-5 to the denominator, making the equation (2^2) (4^3) / (2^5) (2)

Then simplify the terms so you end up with (4)(64) / (32) (2)

Then multiply the denominator so you end up with (4) (64) / (64)

Since both the denominator and numerator have 64, those cancel out leaving you with 4

Less than 3 is 1 and 2.

1= 14 times

2= 16 times.

Add, get 30.

30 is the amount of wanted outcomes, and the total is 200.

30/200 is either 3/20, 0.15, or 15%, because of different formats.

Answer:

The answer to number 4 would be 576cm^3

Step-by-step explanation:

Number 4:

The formula for volume would be V=B·h

to find B your going to find the base of the triangle which would be B=1/2·8·9 so B=36

Then you find the height which is 16 because it connects the two bases of the triangular prism

Next you multiply B·h so 36·16

Lastly, add your units and cube the number because you are foinding volume.
