12 to 16 because all ratios are equivalent
Soloha48 [4]3 years ago
4 0

Hello from MrBillDoesMath!

Answer:  x = 16

Discussion:


We are told that

y/x = 3/4

If y = 12, then

12/x = 3/4.     Multiply both sides by "x" :

(12/x) * x = (3/4) * x  =>

12 = (3/4) *x.  Multiply both sides by (4/3)

12* (4/3) = (3/4) * (4/3) * x  =>

48/3  = x =>

x = 16



Thank you,

MrB

Lines m and n are parallel solve for the following values of x. Tell which theorem you used.
nevsk [136]

Answer:

x=60°

Step-by-step explanation:

angle 135° and (2x+15)° are corresponding and thus are equal

Therefore (2x+15)°=135°

2x=135-15

2x=120°

X=60°

The circumference of the ellipse approximate. Which equation is the result of solving the formula of the circumference for b?
Serhud [2]

Answer:

b = \sqrt{\frac{C^{2} }{2(\pi )^{2} }  -  a^{2}}

Step-by-step explanation:

Given - The circumference of the ellipse approximated by C = 2\pi \sqrt{\frac{a^{2} + b^{2} }{2} }where 2a and 2b are the lengths of 2 the axes of the ellipse.

To find - Which equation is the result of solving the formula of the circumference for b ?

Solution -

C = 2\pi \sqrt{\frac{a^{2} + b^{2} }{2} }\\\frac{C}{2\pi }  =  \sqrt{\frac{a^{2} + b^{2} }{2} }

Squaring Both sides, we get

[\frac{C}{2\pi }]^{2}   =  [\sqrt{\frac{a^{2} + b^{2} }{2} }]^{2} \\\frac{C^{2} }{(2\pi)^{2}  }   =  {\frac{a^{2} + b^{2} }{2} }\\2\frac{C^{2} }{4(\pi)^{2}  }   =  {{a^{2} + b^{2} }

\frac{C^{2} }{2(\pi )^{2} }  = a^{2} + b^{2} \\\frac{C^{2} }{2(\pi )^{2} }  -  a^{2} = b^{2} \\\sqrt{\frac{C^{2} }{2(\pi )^{2} }  -  a^{2}}  = b

∴ we get

b = \sqrt{\frac{C^{2} }{2(\pi )^{2} }  -  a^{2}}

What is the answer to this question? 6 = x/4 +2
yanalaym [24]

Answer:

16

Step-by-step explanation

6 = x/4 + 2

subtract 2 from both sides

4 = x/ 4

since its dividing x and 4 you need to multiply 4 on both sides

16 = x
