1. Solve the equation 2n - 12 = -16
2. A slice of pizza is $3.20 and a drink is $1. You spent $10.60. Write and solve an equation using “p” the number of slices of pizza you bought.
3. Baby calf weighs 150 pounds at birth and gains 2 lbs daily. How many days to get to 224lbs? Write and solve an equation using “d” days for how old he is at 224 pounds.
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 the first step in solving this equation? 2.4n - 6.4 = -14.8
wite it in your way don't copy no ones work and into 3 or 4
1. To solve the equation 2n - 12 = -16, we can start by adding 12 to both sides to isolate the variable. This gives us 2n = -4. Then, we divide both sides by 2 to solve for n, which gives us n = -2.
2. To write the equation for the situation, we know that the cost of p slices of pizza is $3.20p and the cost of the drink is $1. So, the total cost is $3.20p + $1. We also know that the total amount spent is $10.60. Therefore, the equation can be set up as 3.20p + 1 = 10.60. To solve for p, we subtract 1 from both sides, giving us 3.20p = 9.60. Finally, we can divide both sides by 3.20 to find that p = 3.
3. To find the number of days it takes for the baby calf to weigh 224 pounds, we can set up the equation as 150 + 2d = 224, where d represents the number of days. To solve for d, we first subtract 150 from both sides, resulting in 2d = 74. Then, we divide both sides by 2 to find that d = 37.
4. To solve the situation with Rita's stickers, we first need to identify the total number of stickers she initially had. We know that she gave half of them to her friend, which means that the remaining number of stickers is equal to half of the original quantity. Then, her brother gave her 8 additional stickers, which means we can add 8 to the remaining quantity. This gives us the equation (1/2)x + 8 = 12, where x represents the original number of stickers. To solve for x, we can subtract 8 from both sides, resulting in (1/2)x = 4. Finally, we multiply both sides by 2 to find that x = 8.
5. The first step in solving the equation 2.4n - 6.4 = -14.8 is to add 6.4 to both sides of the equation in order to isolate the variable term. This gives us 2.4n = -8.4.
