Alan has to pay Robin $48, but he has only $36 with him. Alan overdraws the remaining amount from the bank to pay Robin. After paying Robin, what will Alan's account balance be?

$-12

Step-by-step explanation:

First, we subtract to see how much money Alan still owed.

48 - 36 = 12

Next, we subtract this number to Alan's account balance because this is the amount of money he needs to borrow from the bank, and which we know to be 0.

0 - 12 = -12

Alan's account balance after paying Robin will be $-12

step-by-step explanation:

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.
