Question

  1. rita started the day with r apps. then she deleted 5 apps and still had twice as many apps as cora has. write an equation that represents the number of apps each girl has.username ritadeleted apps 5total appusername coratotal apps 36

Explanation:

Step1: Define variables for each girl

Let \( r \) = Rita's starting apps, \( c \) = Cora's total apps.

Step2: Set up Rita's remaining apps

After deleting 5, Rita has \( r - 5 \) apps.

Step3: Relate to Cora's apps

Rita's remaining apps = 2×Cora's apps.
\( r - 5 = 2c \)

Step4: Substitute Cora's known app count

From the image, \( c = 36 \). Substitute:
\( r - 5 = 2 \times 36 \)

Answer:

For Rita's starting apps: \( r - 5 = 72 \) (or simplified, \( r = 77 \))
The general equation relating their app counts: \( r - 5 = 2c \)
