*ASAP this is urgent plzzz help me Proportional Relationships

Alexxandr [17]

I don’t have paper on me to solve this but i’m pretty sure you have to set up an equation such as:

2/3 = 5/x then you would solve for x in order to find the question mark.

2/3= x/10.5

and so on and so forth.

sorry if i wasn’t much help! :/

2b^2x^2+3a^2y^2=a^2b^2 for b^2

Artemon [7]

Answer:

${b}^{2} = \frac{3 {a}^{2} {y}^{2} }{ {a}^{2} - 2 {x}^{2} }$

Step-by-step explanation:

We want to solve for b² in

$2 {b}^{2} {x}^{2} + 3 {a}^{2} {y}^{2} = {a}^{2} {b}^{2}$

Combine terms containing b²

$3 {a}^{2} {y}^{2} = {a}^{2} {b}^{2} - 2 {b}^{2} {x}^{2}$

Factor b² to get:

$3 {a}^{2} {y}^{2} = ({a}^{2} - 2 {x}^{2}) {b}^{2}$

Divide by a² -2b²

${b}^{2} = \frac{3 {a}^{2} {y}^{2} }{ {a}^{2} - 2 {x}^{2} }$

Two sections of a class took the same quiz. Section A had 15 students who had a mean score of 80, and section B had 20 students

B, because when you add 90+80 you get 170 and 170/2 = 85
