21 less then four times a number is the same as six times the number plus 11. What is the number

Damm [24]

Answer:

-16 =n

Step-by-step explanation:

Let n= number

4n -21 = 6n +11

Subtract 4n from each side

4n-4n -21 = 6n-4n +11

-21 = 2n+11

Subtract 11 from each side

-21-11 = 2n

-32 = 2n

Divide by 2

-32/2 = 2n/2

-16 =n

I really need help please!!

Using similar triangles, we see that 12/x = x/16. Multiplying by 16x, we see that x^2=12*16=192.

By the Pythagorean Theorem, $12^2+y^2=x^2$ . Since x^2=192, we know that $144+y^2=192$ . Subtracting 144 from both sides, we see that $y^2=48$ , so y= $4 \sqrt{3}$ .
