Answer:
a = -0.6b + 0.2c
Step-by-step explanation:
Simplifying
5a + 3b = c
Solving
5a + 3b = c
Solving for variable 'a'.
Move all terms containing a to the left, all other terms to the right.
Add '-3b' to each side of the equation.
5a + 3b + -3b = -3b + c
Combine like terms: 3b + -3b = 0
5a + 0 = -3b + c
5a = -3b + c
Divide each side by '5'.
a = -0.6b + 0.2c

Step-by-step explanation:
Answer: p = 100
20/p = 2/10; Cross Multiply
(p * 2) = (20 * 10)
2p = 200; divide 2 from both side
p = 100
Check:
Put 100 in for p
20 / 100 = 2 / 10; is true so 100 is correct
