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.
Total money Janice has: $10, so the total cost for the bananas and apples must be less than or equal to $10.
Keeping this in mind, let's break this problem down.
1: The bananas: She needs 5 pounds of bananas, which cost $0.80 per pound. To find the total cost of bananas, multiply the cost by the number of pounds.
5($0.8)=$4.
2. The apples: She also needs 5 pounds of apples at $1.40 per pound. To find the total cost, follow the same process as with the bananas:
5($1.4)=$7 for the total cost of the apples.
3. Now you have two separate costs: one for apples, and the other for bananas. Combined, the total cost is 4+7=11. Because Janice's mother only gave her $10, she's short a dollar. So no, she doesn't have enough money.
Answer:
2n and n + 1 are even if n is odd.
20 * (10.3)*n is even if (10.3)n is odd.
Step-by-step explanation:
Are you talking about the expression 10.3n or simply n ?
If n is an odd number then n+1 is even
2*n is even
