Answer:

86

Step-by-step explanation:

1. a+b=14 ⇒ a= 14-b

2. 10a+b=18+10b+a ⇒ a= 2+b

comparing 1 and 2:

14-b= 2+b ⇒ 2b= 12 ⇒ b= 6

a= 14-b= 8

number = 86

reversed number = 68

Linh buys two T-shirts for $12 each, a pair of shoes for $28, and a pair of jeans for $45. She has a coupon for 30 percent off h

Darina [25.2K]

12x2= $24
24+28+45= $97

So $97 is 100%

So 100%-30% =70% (30% off)
(note: 70% = 70/100 = 0.7)

97 x 0.7 = $67.90

A) The difference between twice the product of a and b and the quotient of these numbers.

lys-0071 [83]

Answer:

(a) 2ab - a/b

(b) c² + d + 2cd

(c) c + c²

(d) Let x be the number that is 1 greater than b, then x = b + 1

Let y be the number twice as large as b, then y = 2b

Then the quotient of x and y is what we want. This is (b + 1)/2b

(e) pq - 3(p + q)

(f) The quotient of n² and n³ + 5, this is

n²/(n³ + 5)
