Answer 1

27-y:25 points

Step-by-step explanation

Step 1

Let y represents the points she scored in the second half

total = 27 points

we also know that

total poitns= points first half+points sencond half

replace

`\begin{gathered} 27=\text{ points first half+y} \\ \text{now, subtrac y in both sides} \\ 27-y=\text{ Point first half} \end{gathered}`

therefore, the expression is

`27-y`

Step 2

now, if she scored 2 poitns in the second half

let

y=2

now, replace

`\begin{gathered} \text{ Points first half= 27-y=27-2=25} \\ so \\ \end{gathered}`

she scored 25 points in the first half

therefore, the answer is

27-y:25 points

I hope this helps you
