Question

if the average is x, x+4 and 12 is equal to 12 what will be the average of xand 32​

Answer 1

Answer:

$\boxed{\text{average of x and 32 = 21}}$

Step-by-step explanation:

$\text{average is x, x+4 and 12 is equal to 12} \\\\ => \frac{x+x+4+12}{3} =12 \\\\ =>\frac{2x+16}{3} =12 \\\\ => 2x+16=12 \times 3 \\\\ =>2x+16=36 \\\\ =>2x=36-16 \\\\ =>2x=20 \\\\ =>x=20/2 \\\\ =>x=10 \\\\ \implies \text{average of x and 32} = \frac{x+32}{2} \\\\ =\frac{10+32}{2} \\\\ =\frac{42}{2} \\\\ =21$

Answer 2

Answer:

x×x+4+12/3=12

2x+16=12×3

2x+16=36

2x=36-16

2x=20

x=20/2

x=10

10+32/2=42/2=21

is the right answer
