The sum of 5% of a number and 9 is 16

netineya [11]

Ok, so first find out what the number actually will be

16 - 9 = 7

So you need to find out the complete number. You can do that by dividing

7 / 5% = 120

So that means the sum of 5% of 120 and 9 is 16.

Wayne is hanging a string of lights 78 feet long around the three sides of his piano, which is adjacent to his house. The length

Sauron [17]

Answer:

The width is 18 feet and the length is 42 feet

Step-by-step explanation:

Let x feet be the width of the patio. The length of the patio is 6 feet longer than twice it’s width, then the length of the patio is 2x+6 feet.

Wayne is hanging a string of lights 78 feet long around the three sides of his patio, which is adjacent to his house. The side with length 2x+6 feet is adjacent to the house, so Wayne is hanging a string along three sides with lengths x ft, x ft and 2x+6 ft.

Hence,

$x+x+2x+6=78\\ \\4x=78-6\\ \\4x=72\\ \\x=18\ ft$
