Question

Jane is painting her room. She mixes 3 pints of blue paint with 4 pints of red paint to get her desired color. Which equation can be used to find the number of pints of blue paint (x) Jane should mix with 16 pints of red paint? A) 3 x = 16 4 B) 3 4 = x 16 C) 3 16 = 4 x D) x 16 = 4 3

Answer 1

Answer: Option 'C' is correct.

Step-by-step explanation:

Since we have given that

Jane mixes 3 pints of blue paint with 4 pints of red paint to get her desired color.

So, the ratio will be

$3:4$

We have 16 pints of red paint and we have to find the pints of blue paint 'say x'.

According to question,

Since there is "direct variation" . So,our equation becomes,

$\frac{3}{16}=\frac{4}{x}\\\\x=\frac{16\times 4}{3}\\\\x=\frac{64}{3}\\\\x=21.34$

Hence, Option 'C' is correct.
