Answer:
How high is the climber?
Step-by-step explanation:
So, he starts at 1200. And then he walks 800 times 3, which is 2100.
So, 2100 + 1200 = 3300
B. 7
49 divided by 7 is 7.
Answer: a:b:c:d = 16:24:30:40
You can also divide the ratio by 2 because all terms have 2 in common. Which would be a:b:c:d = 8:12:15:20
Let L, W and P denote length, width and perimeter.
L = (2/3)W - 5
The perimeter, P, is 2W + 2L, and this, in turn, is
2W + 2((2/3)W - 5), or 2W + (4/3)W - 10, or
(2 + 4/3)W - 10, or (10/3)W - 10
