Marta is planning a field trip to the zoo. Admission to the zoo is $12 per student and $20 per adult. What expression represents the total cost of admission for a group of x students and y adults? StartFraction x over 20 EndFraction + StartFraction y over 12 EndFraction
StartFraction x over 12 EndFraction + StartFraction y over 20 EndFraction
12 x + 20 y
20 x + 12 y
u dont need to anwser free points and brainlist.

12x + 20y = 20 x +12 y

= both Star Fraction X's = 12 x + 20 y,-20 x +12 y

Step-by-step explanation:

thank you !

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.
