Answer:

The amount of money A pays is $\$51$

Step-by-step explanation:

Let

x-----> amount of money A pays

y-----> amount of money B pays

we know that

$x+y=85$ ------> equation A

$\frac{x}{y}=\frac{3}{2}$

$y=\frac{2}{3}x$ ------> equation B

substitute equation B in equation A and solve for x

$x+(\frac{2}{3}x)=85$

$\frac{5}{3}x=85$

$x=85*3/5=\$51$

Find three consecutive odd integers such that the sum of the 1st and 2nd number is 344

olga2289 [7]

Answer:

three consecutive odd integers are.

$171, 173, 175$

Step-by-step explanation:

Let x be the first term of odd integer,

Therefore, the second consecutive odd integers = $x+2$

Similarly, the third consecutive odd integers = $x+4$

Given:

The sum of the first term and second term is 344.

first term + second term = 344

Here first term is x and second term is $x+2$ .

$x+(x+2)=344$

$2x+2=344$

$2x=344-2$

$x=\frac{342}{2}$

$x=171$

Therefore, the first odd integers is 171.

And the second consecutive odd integers = $x+2=171+2=173$

Similarly, the third consecutive odd integers = $x+4=171+4=175$
