Answer:

5 positive x-tiles and 1 positive unit tile to represent 5x+(-1) , explains Gracia's error.

Step-by-step explanation:

Garcia is modeling the equation 5x + (-1) = -2x +6 by using the following tiles

5 positive x-tiles and 1 positive unit tile to represent 5x + (– 1)

2 negative x-tiles and 6 positive unit tiles to represent –2x + 6

we know that

5 positive x-tiles and 1 positive unit tile to represent 5x + ( 1)

while we are given 5x+(-1)

So, there are 1 negative unit tiles

so, option-A

<u>Case 1 :</u>

5 positive x-tiles = 5x

1 positive unit tile = 1

5 positive x-tiles and 1 positive unit tile = 5x + 1

<u>Case 2 :</u>

2 negative x-tiles = -2x

6 positive unit tiles = 6

so, 2 negative x-tiles and 6 positive unit tiles = -2x+6

We see that Gracia has represented the 1st case as 5x+(-1), which should be 5 positive x-tiles and 1 negative unit tile.

Hence the statement : 5 positive x-tiles and 1 positive unit tile to represent 5x+(-1) , explains Gracia's error.

Help me llliad plz neeeeeeed help

Lets get started :)

Diameter = 2.5 ft
Radius = \frac{diameter}{2} = \frac{2.5}{2} = 1.25

a) The Circumference formula of a circle is given in the picture below, we can plug-in the given information

C = 2\pi(1.25) or 2.5\pi
    ≈ 7.85 ft 
(we can leave the answer in terms of pi {\pi})

b) We divide the total number of distance the tire will travel by the circumference to find how many times the tire will roll

\frac{5280}{circumference} = \frac{5280}{2.5 \pi } 
(I have used the value in feet because we found the circumference in feet units and notice that I took the value of circumference to be 2.5\pi instead of 7.85, to increase accuracy)

672.2

The tire will rotate 672 times (a tire cannot roll a decimal times, so we take to the nearest whole number) to travel 1 mile

Jaime has 5 over 11 spaceof a project completed while Tim has finished 7 over 13 spaceof the same project.
faust18 [17]

Answer:

a. Tim has completed a greater amount of work.

b. Together they have completed \frac{142}{143} part of two projects.

Step-by-step explanation:

Let us assume that the project on which Jaime and Tim are working has x amount of space.

Now, given that Jaime has 5 over 11 space of a project completed while Tim has finished 7 over 13 space of the same project.

Therefore, Jaime has completed \frac{5x}{11} amount of space and Tim has finished \frac{7x}{13} amount of space.

a. Now, (7x) \times 11 > (5x) \times 13

⇒ \frac{7x}{13} > \frac{5x}{11}

Therefore, Tim has completed the greater amount of work. (Answer)

b. Together they have completed (\frac{7x}{13} + \frac{5x}{11}) = \frac{(7 \times 11 + 5 \times 13)}{13 \times 11} x = \frac{142}{143}x amount of space out of 2x amount of space. (Answer)
