Isolate the variables. You want to get the five on the same side as the ten, so, you add  five to both sides.

-4b+2b=15

-2b=15
b= -7.5

I believe. You may want to double check my work though.

A luxury resort is offering an incentive discount. If you book your room six months in advance, you will save 15% off the price
Anna [14]

Answer:the total discounted cost for your stay is $1948.2

Step-by-step explanation:

If you book your room six months in advance, you will save 15% off the price of the room. You decide to take advantage of the offer and book a room for 6 nights. If the original price per night for the room is $382, this means that the value of the discount would be

15/100 × 382 = 0.15 × 382 = $57.3

The cost of the room for a night would be

382 - 57.3 = $324.7

Since you are staying for six nights,

the total discounted cost for your stay would be

324.7 × 6 = $1948.2

Why are (1,2) and(2,1) not equal ordered pair? ​
vladimir1956 [14]

Answer:

The pairs ( 1 , 2 ) and ( 2 , 1 ) are not equal because their respective elements are not equal.

Step-by-step explanation:

The pair of elements which are in specific order is called an ordered pair. The pair ( 1 , 2 ) is not same as the pair ( 2 , 1 ). In the pair ( 1 , 2 ) 1 is in the first position and 2 is in the second position. In the pair ( 2 , 1 ), 2 is in the first position and 1 is in the second position.

Two ordered pairs ( a , b ) and (c , d ) are said to be equal if a = c and b = d. We write ( a , b ) = ( c , d ).

Hope I helped!

Best regards!!

11 less than 7 times a number is 5 more than 6 times the number. find the number.
kolezko [41]

Let's translate the words into expressions:

11 less than 7 times a number is 7x-11

5 more than 6 times the number is 6x+5

So we have the equation

7x-11 = 6x+5

Subtract 6x from both sides:

x - 11 = 5

Add 11 to both sides:

x=16
