4.Rita has stickers. She gave half of them to her friend but her brother gave her 8. She ends up with 12 stickers. What arithmetic operations are used to solve this?
5.What is first step in solving this equation? 2.4n - 6.4 = -14.8
wite it in your way don't copy noones work and into 5 or 6
1. To solve the equation 2n - 12 = -16, we can start by isolating the variable "n" on one side of the equation.
Adding 12 to both sides of the equation, we get 2n - 12 + 12 = -16 + 12, which simplifies to 2n = -4.
Next, we divide both sides of the equation by 2 to solve for "n". This gives us (2n)/2 = -4/2, which simplifies to n = -2.
Therefore, the solution to the equation is n = -2.
2. Let's write an equation using "p" as the number of slices of pizza you bought.
The cost of each slice of pizza is $3.20 and you also bought a drink for $1. The total amount you spent is $10.60.
Therefore, the equation can be written as 3.20p + 1 = 10.60.
To solve for "p", we can start by subtracting 1 from both sides of the equation, which gives us 3.20p = 10.60 - 1.
Simplifying the right side of the equation, we get 3.20p = 9.60.
Finally, we divide both sides of the equation by 3.20 to solve for "p". This gives us (3.20p)/3.20 = 9.60/3.20, which simplifies to p = 3.
Therefore, you bought 3 slices of pizza.
3. Let's write an equation using "d" as the number of days since birth for a baby calf to reach 224 pounds.
At birth, the calf weighs 150 pounds and gains 2 pounds each day.
Therefore, the equation can be written as 150 + 2d = 224.
To solve for "d", we can start by subtracting 150 from both sides of the equation, which gives us 2d = 224 - 150.
Simplifying the right side of the equation, we get 2d = 74.
Finally, we divide both sides of the equation by 2 to solve for "d". This gives us (2d)/2 = 74/2, which simplifies to d = 37.
Therefore, the baby calf will weigh 224 pounds on its 37th day of age.
4. To solve the problem of Rita giving half of her stickers to her friend and then receiving 8 more from her brother to end up with a total of 12 stickers, we can use the following arithmetic operations:
First, we divide the total number of stickers she ends up with, 12, by the 0.5 (which represents half). This gives us the value of the original number of stickers she had.
After finding the original number of stickers, we subtract the 8 stickers given by her brother to find the initial amount of stickers Rita had.
Therefore, the arithmetic operations used are division and subtraction.
5. The first step in solving the equation 2.4n - 6.4 = -14.8 is to eliminate the constant term (-6.4) on the left side of the equation.
This can be done by adding 6.4 to both sides of the equation, giving us 2.4n - 6.4 + 6.4 = -14.8 + 6.4.
Simplifying the equation, we have 2.4n = -8.4.
The next step would be to isolate the variable "n" by dividing both sides of the equation by 2.4. This gives us (2.4n)/2.4 = -8.4/2.4.
Simplifying further, we get n = -3.5.
Therefore, the solution to the equation is n = -3.5.
