Hi there
3(p + q) = q
Solve for P
Use the distributive property
(3)(p) + (3)(q) = q
3p + 3q = q
3p = q-3q
3p = -2q
p = -2q/3
The answer is D
If you have any further questions please let me know :)
Answer:
C
Step-by-step explanation:
The last one is absurd. You can't have a ladder reaching higher than itself. The question is a Pythagorean problem.
Givens
a = 3
b = ?
c = 25 feet
Formula
a^2 + b^2 = c^2
Solution
3^2 + b^2 = 25^2
9 + b^2 = 625 Subtract 9 from both sides.
b^2 = 625 - 9
b^2 = 616 Take the square root of both sides.
b = sqrt(616)
b = 24.8
11 squared is 121
20 squared is 400
121+400= 521
The approximate square root of 521 is approximately 22.8254
Answer:
![c = \frac{2a + b}{3}](https://tex.z-dn.net/?f=c%20%3D%20%5Cfrac%7B2a%20%2B%20b%7D%7B3%7D)
Step-by-step explanation:
![3c - b = 2a \\ 3c = 2a + b \\ \frac{3c}{3} = \frac{2a + b}{3} \\ c = \frac{2a + b}{3}](https://tex.z-dn.net/?f=3c%20-%20b%20%3D%202a%20%5C%5C%203c%20%3D%202a%20%2B%20b%20%5C%5C%20%20%20%5Cfrac%7B3c%7D%7B3%7D%20%20%3D%20%20%5Cfrac%7B2a%20%2B%20b%7D%7B3%7D%20%20%5C%5C%20c%20%3D%20%5Cfrac%7B2a%20%2B%20b%7D%7B3%7D)
