If the measure of is and x = 30, which expression could represent the measure of ?

If the measure of BEC is (2x+3) and x=30, which expression could represent the measure of AED?

(3x-27) will represent the measure of AED.

Step-by-step explanation:

Given:

Measure of  

The value of 'x' =

We have to find the expression which could represent the measure of .

Measure of   (vertically opposite angle property).

Lets measure the numeric value of by plugging the value of 'x' in the expression given.

⇒

⇒

⇒

⇒

⇒

⇒

Now plugging the value of 'x' in the expressions given in the options we have to check whether any of the expression is equivalent to or not.

⇒

⇒

⇒

⇒

⇒

So (3x-27) is the appropriate choice.

Option C -

Step-by-step explanation:

Given : The Jones family plans a trip to the amusement park a purchase a family package for $128.00. They also want to buy lunch and souvenir cups. The chicken platter costs $8.50 each and the burger platter costs $9.50 each. The souvenir cups each cost $10.00

To find : Which of the following algebraic expressions can be used to describe the amount of money the Jones family will spend, before sales tax, based on the number of each meal and souvenir cups purchased?

Solution :

Let x represent the number of chicken platters.

Let y represents the number of burger platters.

Let z represent the number of souvenir cups.

A family package cost is $128.00.

The chicken platter costs $8.50 each

The cost of x chicken platter =

The burger platter costs $9.50 each.

The cost of y burger platter =

The souvenir cups each cost $10.00

The cost of z souvenir cups  =

Therefore, Total they spend is

Hence, Option C is correct.
