Consider the expression 12 + 12/13. Using words explain what this problem means. Solve and defend you answer.
Tems11 [23]
This problem is stating that 12 should be added to the quotient of 12 and 13. Since PEMDAS is an expression ' golden rule, first you would divide 12 by 13 to get an approximate answer of 0.92. Then, you would add 12 to 0.92. The sum of 12 and 0.92 is 12.92.

Ahhhh help everyone help me solve this ....​
vovangra [49]

Answer:

y =  \frac{18 {w}^{2}  {x}^{2}  {z}^{2} }{25}

Step-by-step explanation:

\frac{3wx}{ \sqrt{2y} }  =  \frac{5}{2z}  \\  \\  \sqrt{2y}  \times 5 = 3wx \times 2z \\  \\  \sqrt{2y}   \times 5 = 6wxz \\  \\  \sqrt{2y}  =  \frac{6wxz}{5}  \\  \\  {( \sqrt{2y} })^{2}  =  {( \frac{6wxz}{5} })^{2}  \\  \\ 2y =  \frac{36 {w}^{2} {x}^{2} {z}^{2}   }{25}  \\  \\  \\  y =  \frac{36 {w}^{2} {x}^{2}  {z}^{2}  }{25}  \div 2 \\  \\  \\ y =  \frac{36 {w}^{2} {x}^{2} {z}^{2}   }{25}  \times  \frac{1}{2}  \\  \\  \\ y =  \frac{36 {w}^{2} {x}^{2}  {z}^{2}  }{50}  \\  \\  \\ y =  \frac{18 {w}^{2} {x}^{2}   {z}^{2} }{25}
