Answer:

5 lbs

Step-by-step explanation:

1) x = lbs. of coffee at $7 per lb

2) (7)(x) + (4)(10) = (5)(x + 10)

3) 7x + 40 = 5x + 50

7x - 5x = 50 - 40

2x = 10

x = 5 (lbs. of coffee at $7 per lb.)

The perimeter of a rectangle is 48. the length of the rectangle is four less than three times the width. What is the length of t

UkoKoshka [18]

The length of rectangle is: 17

Further explanation:

Given

Perimeter = 48

Let L be the length

Let W be the width

Then

$2L+2W=48\\AND\\L=3W-4$

Putting the value of L in perimeter

$2(3W-4)+2W=48\\6W-8+2W=48\\8W-8=48\\8W=48+8\\8W=45\\\frac{8W}{8}=\frac{56}{8}\\W=7$

Putting W=7 in second equation

$L=3(7)-4\\L=21-4\\L=17$

Hence,

The length of rectangle is: 17
