Help! with explanations if possible

k0ka [10]

Answer:

Step-by-step explanation:

1. according to the condition

$\frac{price \ radio1}{price \ radio2} =\frac{x}{y}$

2. when the both prices are increased the ratio is

$\frac{x+20}{y+20}=\frac{5}{2}$

3. when the both prices are reduced the ratio is

$\frac{x-25}{y-25} =\frac{5}{1}$

4. using the equations written in steps 2&3 it is possible to make up the system of the two equations:

$\left \{ {{\frac{x+20}{y+20}=\frac{5}{2} } \atop {\frac{x-25}{y-25}= \frac{5}{1} }} \right.$

where x=160; y=52.

5. ration x:y=5.

2x=90<br> 3y-2x=90<br> Please tell me work

svp [43]

90 divided by 2= 45 so x=45
2•45=90
So, for the next one y=60 because 90+90=180
3•60-2•45=90
