Answer:

x = 5

Step-by-step explanation:

Since Q is the midpoint of PR,

PQ = QR

=> 3x + 2 = 7x - 18

=> 3x - 7x = -18 - 2

=> -4x = -20

=> x = -20/-4

=> x = 5

Tony’s Electronics is marking down the price of a TV 23% from the original price of $175. Which expression can be used to find t

Arlecino [84]

Answer:

The sale price is $\$134.75$

The expression is $\$175(0.77)$

Step-by-step explanation:

we know that

The sale price is equal to subtract the discount price from the original price

The discount price is equal to multiply the original price by the percent discount in decimal form

Let

x ----> the sale price

y ---> discount price

$23\%=23/100=0.23$ ----> percent discount in decimal form

$y=\$175(0.23)=\$40.25$

$x=\$175-y$

substitute

$x=\$175-\$40.25=\$134.75$

therefore

the expression is

$175-0.23(175)\\175(1-0.23)\\175(0.77)$
