Answer:

x= -3.6

y= -2.8

Step-by-step explanation:

9x +17 =3x-5 ( interior angles are equal)

9x-3x +17= 3x-3x -5

6x+ 17+ 5= -5+5

6x/6= -22/6

x= -3.6

3x-5= 6y+1 ( vertical angles)

3(-3.6) -5 = 6y+ 1

-10.8 -5 -1= 6y +1 -1

-16.8 = 6y

-16.8/6 = 6y/6

y= -2.8

Answer:

The step 4 and 5 describe the errors Stephen made.

Step-by-step explanation:

Given : Stephen evaluated $(6.34\times 10^{-7})(4.5\times 10^3)$ . His work is shown below.

To find : Which two statements describe the errors Stephen made?

Solution :

Step 1 - $(6.34\times 10^{-7})(4.5\times 10^3)$

Step 2 - $(6.34\times 4.5)(10^{-7}\times 10^3)$

Step 3 - $(28.53)(10^{-4})$

Step 4 - $28.53\times 10^{4}$

Error is the step as 4 sign is negative.

So correct step is $28.53\times 10^{-4}$

Step 5 - $28.53\times 10^{3}$

Error is the step as there is 4 in place of 3.

So correct step is $28.53\times 10^{-4}$

The step 4 and 5 describe the errors Stephen made.
