Answer:

x= 5

Step-by-step explanation:

Since RQ= PQ,

3x= 15

<em>Divide both sides by 3:</em>

x= 15 ÷3

\textcolor{red}{x = 5}

\textcolor{steelblue}{\text{Prove for RQ}= \text{PQ}}

Let SP= x

RS= SP= x (given)

Let SQ= y

Applying Pythagoras' Theorem,

<u>In triangle </u><u>QRS</u>

(RQ)²= (RS)² +(SQ)²

(RQ)²= x² +y²

RQ =  \sqrt{ {x}^{2}  +  {y}^{2} }

<u>In triangle </u><u>QPS</u>

(PQ)²= (SP)² +(SQ)²

(PQ)²= x² +y²

PQ =  \sqrt{ {x}^{2} +  {y}^{2}  }

Thus, RQ= PQ.

The cost of item A is $8 and the
yKpoI14uk [10]

Answer: the number of item A that you sold is 11

the number of item B that you sold is 2

Step-by-step explanation:

Let x represent the number of item A that you sold.

Let y represent the number of item B that you sold.

The total number of item A and item B sold is 13. This means that

x + y = 13

The cost of item A is $8 and the

cost of item B is $4. The total amount if money made is $88. This means that

8x + 4y = 88 - - - - - - - - - -1

Substituting x = 13 - y into equation 1, it becomes

8(13 - y) + 4y = 88

104 - 8y = 88

8y = 104 - 88 = 16

y = 16/8 = 2

x = 13 - y = 13 - 2 = 11
