Slope: (y2-y1)/(x2-x1)
(7-2)/(7-4) = 5/3
Solution: the slope is 5/3
You don't just go removing numbers here and there without a good reason. In any case, your whole approach here is wrong. You're calculating 60 percent of 12. But the question says to take 12 out of a group of 60 and tell what percent of the group you have. That's (12/60) x 100.
Okay, 3x just means 3•x. so 3•x-y=15. you would have to have what x and y both mean to get the correct answer. but if they just need it simplified than your answer would be 3•x-y=15
Answer:
20. = 5(ab)^4 / 9mc^7
24. = 9c^4
Step-by-step explanation:
Let cost price be x
according to question
x + 40% of x = 280
x+ 0.4x=280
1.4x=280
x=200
this 200 is the store cost or cost price for store
30%of 200= 60
according to question,
cost for employee= 200-60= 140
