Lisa and daisy work at a hair salon. the salon charges $18 for a hair styling session with lisa and $12 for a session with daisy. the income on a certain day is projected to be $216. this situation can be represented by the equation 18x + 12y = 216, where x is the number of lisa's customers and y is the number of daisy's customers. how many customers would lisa need to serve to attain the projected income if daisy calls in sick that day? (note: x ≥ 0, y ≥ 0, and x and y take only integer values.)

i believe the answer is c.

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.
