Answer:
[tex]R-5=2C[/tex]
Step-by-step explanation:
Let C be the number of apps that Cora have.
We are told that Rita stared the day with R apps. Then she deleted 5 apps. So Rita is left with R-5 apps.
We are also told that after deleting 5 apps Rita still had twice as many apps as Cora has. We can represents this information as:
[tex]R-5=2C[/tex]
Therefore, the equation [tex]R-5=2C[/tex] represents the number of apps each girl has.
Answer:
Rita :R = 2C+5
Cora: C = (R-5)/2
Step-by-step explanation:
Hi, to answer this question we have to write an equation.
Rita has R apps and deletes 5, it means we have to subtract 5 to R. (R-5)
After that she has twice as many apps as Cora has. So, the previous expression is equal to the number of apps that Cora has (C) multiplied by 2.
The whole equation:
2C = R-5
For each girl we have to solve for each variable:
Rita's apps:
2C = R-5
2C+5 =R
R = 2C+5
Cora's apps:
2C = R-5
C = (R-5)/2
