To solve for "r", we can start by isolating the variable on one side of the equation:
r/3 - 4 = 11
r/3 = 11 + 4
r/3 = 15
To solve for "r", we can multiply both sides by 3:
r = 15 * 3
r = 45
Therefore, the solution to the equation r/3 - 4 = 11 is r = 45.
r/3-4=11

ok heres one 7+3m=28 what is the answer
To solve for "m", we can follow these steps:
1. Subtract 7 from both sides of the equation:
7 + 3m - 7 = 28 - 7
2. Simplify:
3m = 21
3. Divide both sides of the equation by 3:
3m/3 = 21/3
4. Simplify:
m = 7
Therefore, the solution to the equation 7 + 3m = 28 is m = 7.
1. Subtract 7 from both sides of the equation:
7 + 3m - 7 = 28 - 7
2. Simplify:
3m = 21
3. Divide both sides of the equation by 3:
3m/3 = 21/3
4. Simplify:
m = 7
Therefore, the solution to the equation 7 + 3m = 28 is m = 7.
you and a friend go to the movies and split the cost of the movie tickets and snacks. you pay the bill. you tell your friend he owes only 9 dollars because you owed him 4 from the last time you went to the movies. HOw mucg was the total bill? let b represent the total bill. identify the correct equation to represent this problem and correct solution
Let's break down the problem first:
- You paid for the bill which included the cost of the movie tickets and snacks.
- You told your friend that he owes you only 9 dollars because you owed him 4 dollars from the last time you went to the movies.
So the amount your friend owes you, let's call it "f", can be found by subtracting the amount you owed him from the total bill, and then dividing that amount by 2 since you and your friend are splitting the cost equally:
f = (b - 4) / 2 - 9
Solving for "b", we can rearrange the equation and substitute in the value we have for "f":
b = 2f + 4 + 18
b = 2(9) + 4 + 18
b = 40
Therefore, the total bill was $40.

that was not one of my answers
my answers are;
A. b/2+4=9;b=10$
B. b/2-4=9;b=$26
C. b/2+9=4;b=$26
D.2b-4=9;b=7.50$
my answers are;
A. b/2+4=9;b=10$
B. b/2-4=9;b=$26
C. b/2+9=4;b=$26
D.2b-4=9;b=7.50$
I apologize for the confusion, but the answer is indeed one of your options:
A. b/2 + 4 = 9; b = 10
To see why:
- b/2 represents the amount each person would pay if they were splitting the cost evenly.
- You subtract the 4 dollars you owe your friend from the total bill before dividing by 2, since you will pay that amount to your friend.
- You then set this equal to what your friend owes you, which is 9 dollars.
- Solving for "b", we get:
b/2 + 4 = 9
b/2 = 5
b = 10
So the total bill was $10.
I hope this clears up any confusion!

Danielle went ice skating. It cost 3 dollars an hour and 5 for skate rental. if Danielle spent 11 dollars, how many hours did she ice-skate?
A. 3h-5=;h=2
B. 5h-3=11;h=1.6
C. 3h+5=11;h=2
D. 5h-3=11;h=2.8
A. 3h-5=;h=2
B. 5h-3=11;h=1.6
C. 3h+5=11;h=2
D. 5h-3=11;h=2.8
We can start by setting up an equation based on the information given:
The cost for skate rental plus the cost per hour of skating is equal to $11.
5 + 3h = 11
Subtracting 5 from both sides gives:
3h = 6
Dividing by 3:
h = 2
Therefore, Danielle ice-skated for 2 hours. The correct answer is A. 3h-5=0;h=2.
The cost for skate rental plus the cost per hour of skating is equal to $11.
5 + 3h = 11
Subtracting 5 from both sides gives:
3h = 6
Dividing by 3:
h = 2
Therefore, Danielle ice-skated for 2 hours. The correct answer is A. 3h-5=0;h=2.
