Select all (more than one) the situations that can be represented by the equation 1/2(x+40)=60.
question 2 options:
a)40 more than 50% of a number is 60.
b) 60 is half the sum of a number and 40.
c)a test is worth 100 points. each question, x, is worth 1/2a point.
d)a store has a sale in which all items are 50% off. at the store, tony spends a total of $60 for a jacket that costs x dollars and a pair of pants that costs $40.

Option B) 60 is half the sum of a number and 40.

Option D) A store has a sale in which all items are 50% off. At the store, Tony spends a total of $60 for a jacket that costs x dollars and a pair of pants that costs $40.

Step-by-step explanation:

we have the equation

Verify each case

case A) 40 more than 50% of a number is 60.

Let

x -----> the number

The situation is

therefore

The situation cannot be represented with the given equation

case B) 60 is half the sum of a number and 40

Let

x -----> the number

The situation is

Rewrite

therefore

The situation can be represented with the given equation

case C) A test is worth 100 points. Each question, x, is worth 1/2 a point

Let

x -----> the number of questions

The situation is

therefore

The situation cannot be represented with the given equation

case D) A store has a sale in which all items are 50% off. At the store, Tony spends a total of $60 for a jacket that costs x dollars and a pair of pants that costs $40.

Let

x -----> the cost of a jacket

The situation is

therefore

The situation can be represented with the given equation
