Question

Christina and Spencer have 120 baseballs together. Spencer has 28 more baseballs than Christina. How many baseballs are in Spencer's collection? How many baseballs are in Christina's collection?

Answer

"Okay class, we have Christina and Spencer here with their baseball collections. Christina has 46 baseballs and Spencer has 74 baseballs. Can anyone tell me what an equation is? Correct, an equation is two or more expressions with an equal sign. Now, we know that together, Christina and Spencer have 120 baseballs. Let's use x to represent the number of baseballs Christina has and we know that Spencer has 28 more than Christina, so that means x + 28 represents Spencer's collection. Putting this together, we can create an equation: x + (x+28) = 120. To solve for x, we simplify by combining like terms: 2x + 28 = 120. We want to isolate x so we subtract 28 from both sides to get 2x = 92. Finally, we divide both sides by 2 to get x = 46. So Christina has 46 baseballs and Spencer has 46 + 28 = 74 baseballs in their collections. If you want to learn more about equations, you can visit brainly.com/question/10413253. #SPJ1"
