Answer:

  1. 1/4
  2. 3/5

Step-by-step explanation:

You find the part by expressing the ratio as a fraction, then simplifying.

1. 5/20 = (1·5)/(4·5) = (1/4)·(5/5) = 1/4

5 is 1/4 of 20.

__

2. 12/20 = (3·4)/(5·4) = (3/5)·(4/4) = 3/5

12 is 3/5 of 20.

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
dsp73

Answer:

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
