2. If A is 50% larger than C, and B is 25% larger than C, then A
is what percent larger than B?

A is 20% larger than B

Step-by-step explanation:

Define x:

Let c be x

a is 50% larger than c

⇒ a = 1.5x

b is 25% larger than c

⇒ b = 1.25x

Difference of a and b:

Difference = 1.5x - 1.25x - 0.25x

Find the percentage difference:

Difference = (difference / b ) x 100

Difference = ( 0.25x / 1.25x ) x 100 = 20%

a is 20% larger than b.

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
