Answer:
r - 5 = 2c
r = 75
Step-by-step explanation:
To write an equation for the problem, we first need do declare the value of the number of apps cora has.
Let c = Cora's apps
r - 5 = 2c
r - 5 is used to indicate that Rita deleted 5 apps.
2c is used to represent the twice the number of apps Cora has.
Now you said that Cora had 35 apps.
Let's plug that into the equation.
r - 5 = 2c
r - 5 = 2(35)
r - 5 = 70
Now we transpose the -5 to the other side to leave r.
r = 70 + 5
r = 75
So if Cora has 35 apps, then Rita will have 75 apps.
Answer:
10.5
Step-by-step explanation:
1.5 inches
.5 and 1.5 =3
3x3.5=10.5
Answer:
B. 31r − 71 is the answer!
Let the number be x. Then 1.25x = 325, or x = 260.
20% less than 260 is 0.80(260) = 208
