Answer:
p = (7r+16) / (4-q)
Step-by-step explanation:
4p - 7r = pq + 16
Add 7r to both sides.
4p = pq + 16 + 7r
Subtract pq from both sides.
4p - pq = 7r + 16
Factor out p from the left side.
p(4 - q) = 7r + 16
Divide both sides by (4 - q).
p = (7r + 16)/(4 - q)
The 7r and the 16 could be in either order, like 7r+16 or 16+7r. You could show that the answer is a fraction with 7r+16 on top and 4-q on the bottom. If you are writing or on the computer selecting a fraction that is stacked you don't need need the parenthesis.
Answer:
20 feet
Step-by-step explanation:
To find the length of the totem pole's shadow, we need to know that the rate between the man's height and his shadow's length is the same rate of the totem pole's height and its shadow's length.
So, if we call the length of the totem pole's shadow 'x', we have:
6 feet / 2.5 feet = 48 feet / x feet
x = 2.5 * 48 / 6
x = 20
So the length of the totem pole's shadow is 20 feet.
