The length of the second side of a triangle is 2 inches less than the length of the first side. The length of the third side is 12 inches more than the length of the first side. the perimeter of the triangle is 73 inches. Find the length of each side of the triangle.

The lenght of the tree sides of the triangle are:

first side: 21 inches

second side: 19 inches

third side: 33 inches

Step-by-step explanation:

a + b + c = 73

b = a - 2

c = a + 12

a = leght of the first side of the triangle

b = lenght of the second side of the triangle

c = lenght of the third side of the triangle

then:

a + (a-2) + (a+12) = 73

3a - 2 + 12 = 73

3a + 10 = 73

3a = 73 - 10

3a = 63

a = 63/3

a = 21 inches

b = a - 2

b = 21 - 2

b = 19 inches

c = a + 12

c = 21 + 12

c = 33 inches

Check:

21 + 19 + 33 = 73

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.
