Brandon uses the steps below to solve the equation 15x+6=14x+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?

No he was not correct

Step-by-step explanation:

The Equation is 15 x + 6 = 14 x + 5

now By the steps brandon used let us solve the question

Step 1 : Add 14 negative x tile to both sides

which will make the equation

15x + 6 - 14x = 14x + 5 - 14 x

x + 6 = 5  (ii)

Step 2: Add 5 negative unit tiles to both sides of equation (ii)

which will make the equation

x +6 - 5 = 5 - 5

x + 1 = 0  (iii)

Step 3: x =1 is the answer

but from equation (iii) we see that

x + 1 =0

by adding -1 on both sides

x + 1 -1 = 0-1

x = -1

So the step three done by Brandon is wrong which explains he was not correct

D.) Brandon is not correct because he should have added 6 negative unit tiles to isolate the variable in step 2.

10.416 meters per second

step-by-step explanation:

distance=1 00 meters

time= 9.6 seconds in decimal form or 9 3/5 as a mixed number

average speed= 100/9.6

=10.416 meters per second or 10 52/125 as a mixed number.

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w
