Answer:
210 feet
Step-by-step explanation:
Lets say we start at 0 feet
Now all we gotta do is treat rising as addition and dropping as subtraction
0 + 400 = 400 - 90 = 310 + 100 = 410 - 200 = 210
Therefore your final height is 210. If you need further explanation just ask
A diagram is attached if you're still confused (Sorry about the quality, lightshot does not do curves well)
ITS IS 8x-7y-5z=15 I THINK'
Answer:
1) 12 - 8/3 = ((12*3)-(8))/3 = 28/3
2) 10/ (4/7) = (10/1)*(7/4) = 70/4
3) 12/5 + 4/6 = ((5*4)+(12*6))/(5*6) = 46/15
Check the picture below.
you can pretty much count the units off the grid.
recall area of a rectangle is simply width*height.
The answer is 2:1 because at first your ratio would be 18:9 but if you divide that by 9 (for simplifying purposes) than its 2:1
