Answer: B
Step-by-step explanation: 3^4 is 81, and 3^2 is 9. 81/9 is 9. :)
Step-by-step explanation:
If f = price of filing cabinet and c = price of cupboard we can make up the equation
2f + 4c = 800
we also know that f = 3c, so can substitute that into equation
2 (3c) + 4c = 800
6c + 4c = 800
10c = 800
c = 80
f = 240
Answer:
I'm not sure
Step-by-step explanation:
First you put your 2,000 lb. Then you subtract 170lb from it.
2,000 - 170 = 1,830. So you have 1,830 available for freight.
1,830 divided by 69 = 26.5.
Since you can't cut a box in half, and you don't want to overload your lift, your answer is 26 boxes.
You can use two method
First method: form a triangle from x = 4 to x = 7. See vertically and horizontally (count the squares). It would be 5 and 3. Therefore 5/3 would be the slope.
Second method: use the slope formula
Determine 2 points on the graph
(4,0) and (7,5)
Formula: (y2-y1)/(x2-x1)
(5-0)/(7-4) = 5/3
The slope is 5/3
