A shopping mall has a moving sidewalk that takes shoppers from the shopping area to the parking garage, a distance of 220 ft. If your normal walking rate is 5 ft/s and the moving sidewalk is traveling at 3 ft/s, how many seconds would it take for you to walk from one end of the moving sidewalk to the other end?

So you’d add 5 and 3 so it’s 8 ft/s

You then divide 220/8

So it should be 27.5 seconds.

Sorry about that other guy. Hope this helps!

A: 1/10

B: 1/5

C: 4/5

D: 5/1

a b c d idek bahaha

The answer is B: 1/5

Because there are 2/10 red pens which can be simplified to 1/5.

15.it will take 88 minutes to add 16 seats.

It will take 104.5 minutes to add 19 seats.

**Step-by-step explanation:**

Let m represent number of minutes.

We have been given that an assembly line worker at Rob's Bicycle factory adds a seat to a bicycle to a rate of 2 seats in 11 minutes.

We will use proportions to solve our given problem.

To find the time taken to add 16 seats, we will in our proportion as:

Therefore, it will take 88 minutes to add 16 seats.

To find the time taken to add 19 seats, we will in our proportion as:

Therefore, it will take 104.5 minutes to add 19 seats

This is trickery I might can get it

An art class is making a mural for their school which has a triangle drawn in the middle. The length of the bottom of the triangle is x. Another side is 9 more than three times the length of the bottom of the triangle. The last side is 9 more than the bottom of the triangle. Write and simplify an expression for the perimeter of the triangle. What is the expression for the perimeter of the triangle?

**Answer:**

The perimeter of the triangle can be expressed as 5x + 18.

**Step-by-step explanation:**

Perimeter of an object is the sum of the length of its sides.

For the required triangle, we have;

length of the base = x

length of the second side = 3x + 9

length of the third side = x + 9

Perimeter of the triangle = length of the base + length of the second side + length of the third side

= x + (3x + 9) + (x + 9)

= x + 3x + 9 + x + 9

= 5x + 18

The perimeter of the triangle can be expressed as 5x + 18.

4(2)+3(b-4(2))-2(2)=8

9514 1404 393

**Answer:**

-24

**Step-by-step explanation:**

We can simplify this to ...

b^2 +3(b -b^2) -2a

= b^2 +3b -3b^2 -2a

= **-2b^2 +3b -2a . . . . . . . simplified form**

This can be made easier for evaluation by factoring out b.

= (-2b +3)b -2a

Using the given values, this is

= (-2(4) +3)(4) -2(2)

= (-5)(4) -4

= **-24 . . . . value of the expression**

parallelogram has vertices at (4,4), (7,4), (5,2), and (2, 2). The parallelogram is translated 7 units down and reflected across the y-axis. What are the coordinates of the first point of its image (4,4)?

**Answer:**

**Step-by-step explanation:**

So we move the parallelogram down 7 units and get the coordinates: (-3,4) (0,4) (-2,2) (-5,2)

Then the equation for reflecting across the y-axis is (x,y) ---> (-x,y) Then I think you can solve it from there. Just take the x points and make them the opposite charge.
