Brandon uses the steps below to solve the equation 15 x + 6 = 14 x + 5 using algebra tiles.Step 1 Add 14 negative x-tiles to both sides.
Step 2 Add 5 negative unit tiles to both sides
Step 3 The solution is x = 1.

Which explains whether Brandon is correct?
Brandon is correct because he has the correct solution in step 3.
Brandon is correct because he forms zero pairs to isolate the variable by using the lowest coefficient each time.
Brandon is not correct because he should have performed step 2 before performing step 1.
Brandon is not correct because he should have added 6 negative unit tiles to isolate the variable in step 2.

Answers

Answer 1

Answer:

The correct option is Option D: Brandon is not correct because he should add -6 on both sides to isolate the variable in step 2.

What is the linear equation?

The linear equation is an equation where the highest degree of the variable used in the equation is 1.

For example 2x+5=25

Given the equation is 15x +6= 14x+ 5

In order to the linear equation first, try to keep the constant and the variable part to one side by adding or subtracting the constant term.

Then divide the coefficient of the variable (if the coefficient is not equal to 1) on both sides.

Here the given equation is 15x +6= 14x+ 5

Step-1: adding -14x on both sides

⇒15x +6 -14x= 14x+ 5 -14x

⇒x+ 6= 5

Step-2: adding -6 on both side

⇒x+ 6-6 = 5-6

Step-3: solution will be -1

⇒x= -1

Therefore the correct option is Option D: Brandon is not correct because he should add -6 on both sides to isolate the variable in step 2.

2) On a flight from New York to London, an airplane travels at a constant speed. An equation relating the distance traveled in miles, d, to the number of hours flying, t, is t= d. How long will it take the airplane to travel 800 miles? Show your work 500

Answers

The equation for relation of time with distance travelled is,

$t=(1)/(500)d$

Substitute 800 for d in the equation to determine the time required for travelling 800 miles.

$\begin{gathered} t=(1)/(500)\cdot800 \n =(8)/(5) \n =1.6 \end{gathered}$

So airplane take 1.6 hours to travell 800 miles.

There are four shelves of books along a wall in the library. On the top shelf, 16 of the 126 books are checked out. On the second shelf, 8 of the 137 books are checked out. On the bottom shelf, 17 of the 138 books are checked out. How many books are currently on the four shelves?

Answers

1st shelf = 126 - 16 = 110

2nd shelf = 137 - 8 = 129

3rd shelf = Doesn't say

Last shelf = 138 - 17 = 121

Add:

121 + 129 + 110 = 360

I think the answer is 360 but since it doesn't mention anything about the 3rd shelf, I'm not sure.

Hope this helped☺☺

What’s the volume of the pic

Answers

Answer:

100 $\pi$ cubic cm

Step-by-step explanation:

The volume of a cone can be represented by the formula $(1)/(3) \pi r^(2) h$ . Since we know the radius is 5, all we need to find id the height. To do that, we can use the Pythagorean theorem, and see that the height is equal to 12. Plugging the numbers into the formula gives us:

$V =(1)/(3) \pi (5^(2)) (12)$

$V = 100\pi$
