Directions: Write expressions to represent the quantities described below. a. Georgia is 4 years younger than Tristan. If Tristan is t years old, how old is Georgia? Also, if Steven is twice as old as Georgia, how old is he? b. 150 people went to see "Ode to Algebra" performed in at DCP school auditorium. If the number of children that attended the performance was c, how many adults attended? c. The cost of a new CD is $14.95, and the cost of video game is $39.99. How much would c CDs and v video games cost? d. A hotdog, (h) cost $3 and a corndog, (c) cost $2.75. If $250 was collected, write a mathematical sentence to represent this information. Part a: Part b: Part c: Part d:

to determine the unit cost your would divide the total cost by the number sold.

7 bagels for $4.41       $4.41/7 = $.63 each at fresh side

5 bagels for $3.60         $3.60/5 = $.72 each at value mart

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
