How the heck do you solve these type of problems?
Trava [24]
21) 3(2j-k)=108 It is asking you to set the equation equal to j
distribute the 3
6j-3k=108
move k to the other side by adding on both sides
6j=108+3k
divide everything by 6
j=18+0.5k

The width of a rectangle is 38 centimeters. the perimeter is at least 692 centimeters. write an inequality that represents all p
abruzzese [7]

Width of the reactangle = 38 cm

Minimum perimeter = 692 cm

Let the length of the rectangle be x cm

We know that,

Perimeter of rectangle = 2 * (length + width)

Since the perimeter should be atleast 692 cm. Therefore,

2 * (x + 38) > 692

2x + 76 > 692

2x > 692 - 76

2x > 616

x > \frac{616}{2}

x > 308

Hence, the length of the rectangle should be more that 308 cms.
