Answer:
Option D
Step-by-step explanation:
<u><em>Using Unitary Method:</em></u>
10 rotations = 1 minute
=> 1 rotation = 1/10 minute
Multiplying both sides by 43.5
=> 43.5 rotation = 
minutes
=> 43.5 rotation = 4.35 minutes
Answer:
72
Step-by-step explanation:
Multiply 8 and <em>n </em>to get 8n
Multiply 3 and 192 to get 576
Write them equal to each other 
To isolate the variable divide by 8 on both sides

Answer:
y = 8x + 8
Step-by-step explanation:
The y-intercept is already given so we have our b = 8 so y = mx + b becomes y = mx + 8. Now we need to figure out the slope so looking at the chart I need to figure out what number when multiplied by the x value and added to b equals the y value. The answer is 8 because when we multiply it by 1 and add it to 8 we are left with 16, which supports the chart. The equation in slope intercept form is now y = 8x + 8
