7. The length of a rectangle is 3 centimeters less than twice its width. The perimeter of the rectangle is 48 cm. What are the d
irga5000 [103]
The answer is b

The perimeter of a rectangle is 2(l + w) so in this case, it is 2(15 + 9) and that is equal to 48. But so at c and d. So u need to multiply the width by 2 (9*2=18) and then you’ll see that 18-3=15. And therefore, the length is -5 and the width is 9

Math help i need to get 5 right......please
brilliants [131]

Answer:

  f^-1(x) = x +6

Step-by-step explanation:

To find the inverse of the function

  y = f(x)

solve the equation

  x = f(y)

for y.

Here, you want ...

  x = f(y)

  x = (y -6)

  x +6 = y . . . . . . add 6 to both sides

  \boxed{f^{-1}(x)=x+6}\\

A publisher needs to send many books to a local book retailer and will send the books in a combination of small and large boxes.
dezoksy [38]

Answer:

20*s+30*l = 280

4*s=l

Step-by-step explanation:

Let's say that the number of small boxes is s and the number of large boxes is l. Then, 20*s equals the amount of books in small boxes (as there are 20 books per small box), and 30*l for the amount of books in large boxes. Then, we know that 4 times the amount of small boxes, s, equals l, so 4*s=l. Then, as we know that the amount of books that can be held is 280, we can add the amount of books for each type of box, or 20*s+30*l, to get 280. Our equations are as follows:

20*s+30*l = 280

4*s=l

As we can define l in terms of s, making it so that we can limit the top equation to 1 variable, we can use this to determine the number of each type of box
