1) isolate y
4x + 5y = 60
-4x -4x
_____________
5y = -4x + 60
2) make y so that is is alone with no numbers beside it
5y = -4x + 60
__________
5
y = -4/5x + 60
3) the slope is ALWAYS the number to the left of x, even if it's a fraction. It's it a decimal, convert to a fraction. The last number (in this case is 60) is where the slope crosses the y-axis on the coordinate plane.
The slope is -4/5x + 60
Answer:
67
Step-by-step explanation:
basically 1st you have to multiply the cost of food so 4 times 8
2nd you already know the cost of the room
so 3rd add the values
cost of food=32 dollars
cost of roon=35
32 plus 35 =67 $
8 out of 12 people were happy.
8/12 reduces to 2/3 of the people were happy.
Multiply the total people surveyed by 2/3:
126 x 2/3 = (126 x 2) /3 = 252/3 = 84
84 people were happy.
